Otopharynx lithobates

11. September 2017

Today we took the photo equipment in our fishhouse (instead of taking fish from the fishhouse in the phototank), for here in one of our tanks a great show is presented: 50 sexually ripe (7-10 cm long) Otopharynx lithobates, more than half of them males in breeding mood. Wow.

In the natural habitat, males of this species inhabit caves. The bright head stripe is a distinctive feature for females passing the cave. For each females a courtship display is started immediately. In the home aquarium one must take care that females which are not willing to spawn can hide. In the wild they can easily swim away, but in the tank the males can become pretty nasty in cases not enough hiding places are provided for the females.

Otopharynx lithobates feeds on plankton in the wild and can be easily fed by a variety of usual ornamental fish food items. The pH must not sink below 8 in long time sight; otherwise these cichlids, like most cichlids from lake Malawi, are not much demanding and easy to care.

A visit at ornamental fish breeder Jülich

8. September 2017

Where do the ornamental fish in the trade come from? The largest amount for sure from breeding installations in south east Asia, followed next by Israel and Czechia. But there do exist als smaller, more specialized breeding facilities that breed the unusual type of fish. We always try to be attractive as trade partners for those, despite the fact that our company – a wholesaler for wholesalers – usually pays less than our competitiors. But due to our good contacts worldwide and the export trade we most often find a cooperation that satisfies the needs for for both sides.

Red backed angels, a pure wild variety

One of these specilized breeders, Kurt Jülich, had an „open house day“ and we took the opportunity to visit his fishhouse and to talk a bit more intensivly than is possible in our often hectic daily buisiness. We already obtain beautiful angels – both domesticated sports like the Red Devil and pure wild strains – for some years from Kurt. He also suplies us with rarities, like the red lipped Satanoperca rhynchitis, other cichlids, plecos and corys.

Every detail in the facility shows the practitioner. May it be the way the lamps are placed over the tanks, the devices for the waterchange, details of feeding or filtering: one sees that the motto is: thinking first, doing next. But nevertheless the point of basic interest is the animal. And anyone can see: Kurt still burns for fishes. If a species takes his attention he will not rest until it is „cracked“. The economic success is not of much importance at that stage. A good example is the red whiptail cat. We had by chance a red specimen among our wild collected Hemiloricaria lanceolata from Paraguay. The fish was given along with some regular specimens from the same importation to the breeder we trust: Kurt. And in fact Kurt was able to reproduce the fish and now he has a nice stock of them. Not too long and they will be able to come on the market. In other species, like Biotodoma cupido „Coari“, Kurt was not successfull yet, but tis is, we are sure for that, only a question of time. 

Geophagus mirabilis

Biotodoma cupido “Coari”

L-numbers: breeding

Kurt´s wife, Monika, also is a fish breeder, but she is also keen for Bromeliads, Tillandsias, Orchids and othher green gems. Kurt and Monika are perfect partners. Otherwise it would not be possible to keep such a large amount of livestock in such a perfect condition. And one thing is for sure: at Jülich´s always „after the project“ is „before the project“. There are plans without an end and – to avoid to become boring – hobbys. For example there is just for fun a large collection of blueberrys – not deep frozen fruits, but the complete bushes!

Of course a deep love and respect for ceatures it is necessary to have such a great success in keeping them. But as much important is knowledge. Jülichs are proud that their love for creatures is shared by their children. Both are biologists, the daughter a geneticist with worldwide reputation, the son is a docent in a university in China. But there is no distance great enough to hinder the children to help their parents in case they need help or device!

We enjoyed our vistit at Jülich´s place a lot, not at least the excellent home made food and look forward for all the wonderful fish from this very nice facility.

New Guppy: Elephant Ear

6. September 2017

The pectoral fins in Guppys are usually transparent. But there do exist sports with black pectoral fins, like the so called „nigrocaudatus“-types and the Moskow Guppys. Breeders have made this peculiarity the target of their most recent new sport. Obviously initially only colourful guppys with pitchblack pectorals were planned, but then the breeders discovered that the pectorals can also become larger by selective breeding. So the elephant ears in guppys developed, a really matching common name!

Hyphessobrycon cf. agulha Red Tail

1. September 2017

We received a  new species of tetra in number which reached us in former times in single specimens only from the Rio Negro region. Without any doubts the animals are identical with the tetra illustrated on page 472 of „the bible of tetra lovers“, Gery´s „Characoids of the world“. The caption says „Hyphessobrycon agulha, or close to it“. 

In contrast to all the different varieties of tetra that look similar this one has very attractive red stripes in the caudal fin and the dorsal fin. This new tetra is comparable in respect of aquarium demands to a very well known one, namely the Black Neon, Hyphessobrycon herbertaxelrodi.

Hypoptopoma psilogaster

1. September 2017

The genus Hypoptopoma comprises small to medium sized loricariids. The largest species known becomes about 10 cm long. At the first glimpse they look much alike a Otocinclus, but larger. Typical for members of Hypoptopoma is the position of the eyes. They are placed in way at the side of the head that the fish can look over almost 360° when it sits on a plant. This feature can be found among the loricariids only in Hypoptopoma and Oxyropsis. The latter, however, has a flattened caudal peduncle, while in Hypoptopoma the caudal peduncle is oval in cross section.

Sadly determination of species of Hypoptopoma is a tricky thing, although in 2010 a throughout taxonomical revision of the genus was published. Last week we obtained a species of Hypoptopoma from Peru which we had not seen before. The pattern of the caudal fin seemed to be very characteristic and led to the determination of Hypoptopoma psilogaster. Now the fish are very well settled and things look not that definite anymore. But the place of origin fits to H. psilogaster. Maybe our fish represent even a mix of very similar species. Anyway: these are pretty algae eaters and a nice relief!

Guppy Full Platinum

30. August 2017

My dear! After 15 years of pleasureful co-operation our flashlight installation of the photo tank crashed. Today the substitute arrived and we tested it with the latest guppy sport from Sri Lanka: Full Platinum. As anybody knows who has ever tried it: totally white and totally black fish are the hardest challenge in respect of flashlight settings. What can we say: it works!

Luciocephalus pulcher

28. August 2017

The pikehead, Luciocephalus pulcher, is a highly specialized anabantoid, a relative of the chocolate gouramies. Like the latter the pikehead is a mouthbrooder. Luciocephalus is the only true predator among the various anabantoids; in its natural habitat it feeds preferably on shrimps. The calm, beautiful animal (Latin pulcher = beautiful) would for sure be a favorite aquarium fish despite it is always hungry, but there is a big problem: Luciocephalus is among the most sensitive fish at all. This is why we are very glad that our most current importation of the fish is absolutely problem-free. We obtained the adult, about 11-13 cm long pikeheads via Singapore. Sadly we don´t know the collecting site, for our pikeheads are not only extraordinary healthy but also extraordinary coloured.

Usually the pikehead has a broad, horizantal brown band along the flanks. Only when the fish are under distress or during mating this band vanishes and irregular spots are visible. Our new importations shows this spotted pattern now since they arrived 10 days ago. We have no satisfying explanation for the phenomenon, maybe currently is the breeding season for pikeheads?

Poecila mexicana Campeche

23. August 2017

The wild mollys from Central America were always and will stay an enigma for generations of scientists. In each brook the fish look somewhat different. And as if that would not be eough, they also have within every population different shaped males: small and slender early ripe male, large and deep bodies late ripe males and males that are somewhere in between. So it isn´t sure at all, if the splendid fish we can offer now  – they were bred in Southeast Asia – really belong to the species P. mexicana or to P. sphenops or to P. limantouri. However, from a practical point of view these questions are rather irrelevant. 

It is very important to supply always the additional term „Campeche“ – this is the locality where the initial stock has been collected – for otherwise unwanted crosses cannot be excluded.

These wild type mollys are a real challenge for hobby breeders. In contrast to Black Mollys, Silver Mollys and so on the young fish grow extremely slowly. But the adult fish reward the keeper with their lively behaviour and the brillant colours. By the way: the ability to change the coloration is breathtaking. Within seconds the males change from the silvery neutral pattern to the blue-black display-pattern. If the fish are disturebed they can become pale at a glimpse. But the good news is: after only a few days of settling the fish only hardly can become disturbed….

Badis autumnum

21. August 2017

The number of species of chameleon fish has increased drastically in the past years. Until the year 2002 only one genus and ones species with four subspecies were accepted, now there are two genera (Badis and Dario) with 23 species in Badis and 6 in Dario. One of the latest described species is Badis autumnum, which was formally named only in 2015. It is called the „red spotted badis“ in the international trade. Like in all members of the genus Badis the fish can change the coloration very fast, thus the name chameleon fish.

There are three components in the pattern that allows the recognition of the species despite all colour changes: the broad band behind the eyes in combination with the lack of a so-called cleithral spot on the shoulder (present in most other species) and the tail spot that reminds one in a T lying on the side. Additionally the fish displays in most moods a red spot on most scales of the flank that give the fish a pretty attractive coloration. But – this is visible on one of the pictures that accompany this post – fish that are surpressed by a dominant conspecific can even be very pale, almost white. It is very fascinating to observe a tank with Badis and to try to understand the „language of fishes“ spoken in changing coloration.

Moreover, Badis autumnum is a energy saving fish. It originates from the north of India and needs no additional heater most of the year. Only for breeding the temperature should raised to 24-26°C, most of the year 18-22°C are enough and in winter temperatures can be even as low as 14-16°C. All species of chameleon fish avoid dried food, but frozen food is readily accepted and – of course – live food, too. Maximum size of the species is about 6 cm.

Channa sp. „Burmese Red Rim Rainbow“

18. August 2017

Finally we were able to import a number of specimens of this exttemely beautiful, small species of snakehead from Burma. The fish attain a maximum length of about 12-15 cm and are a close relative of Channa gachua. However, the body of „Red Rim“ is much more depressed. In respect of coloration one feature makes „Red Rim“ unique: a great number of small black dots, which are lacking in almost all other members of the Channa-gachua-complex.

One year ago we obtained the first specimen of this new species. That animal had no red rim along the caudal fin, but our current imports have. This obviously is rather an individual character, a phenomenon known in other species of the Channa-gachua-complex, too. Hobbyists specialized in snakeheads know that dwarf also under the name of Channa sp. „Red Fin“.

This is a subtropical species and should not be kept the whole year through at high water temperatures. It s also very likely that „Red Rim“ usually lives in flowing water. When the fish are kept indoors they do not need an additional heater. During the warm season they can be kept even in outdoor tanks, but one has to make sure that the snakeheads by no means can get out of the tank. „Red Rim“ prefers to feed on insects (crickets etc.), but they also feed readily all usual types of frozen or live fishfood as long as it is not too tiny. Most probably „Red Rim“ is a mouthbrooder like Channa gachua.

Corydoras burgessi

18. August 2017

Now the season for the very beautiful and much beloved orange blotch corys has started. There does exist a good number of different species and varietoies, all have in common a brightly shining spot on the neck. Depending on light this glows from yellow to almost red. This glowing spot helps the fish in the black waters of their homeland to stay together in a school.

In the past years it was often difficult for us to obtain Corydoras burgessi. Most often varieties reached us, for example spotted ones that were not as popular as the plain varieties among many of our customers. But now – finally – the pure stuff is available agian!

Mastacembelus pantherinus

17. August 2017

Once more we were able to import an extemely rarely offered species of spiny eel, namely Mastacembelus pantherinus. In the internet this species is in general named M. dayi, but M. dayi has recently proofed to by a synonym of M. alboguttatus. Researcher Ralf Britz – he described, by the way, also M. pantherinus – has solved this confusing puzzle only some weeks ago.

Mastacembelus pantherinus originates from Burma. t has been collected so far only in lake Indawgyi and its affluents. The species attains a maximum length of at least 50 cm and is a large member of the genus. Our specimens currently are 20-25 cm long.

Laetacara curviceps

11. August 2017

Quite a long time before the species of Apistogramma became popular in the hobby, another species of dwarf cichlid from Brazil was a favorite aquarium fish: Laetacara curviceps, the flag acara. At these times it was called Aequidens curviceps. Sadly the fish became rather rare in the past years. So we are glad that we can offer currently very nice German bred specimens of this small, peaceful and beautiful cichlid.

Xiphophorus hellerii „Broccoli“

11. August 2017

What is a Broccoli swordtail? A green swordtail that smells like cabbage? No, not at all! If one crosses a simpson swordtail – simpsons are the swordtails with the long dorsal fin – with a lyretail swordtail – lyretails have prolongations in all fins – some of the offspring have a very long simpson dorsal fin. In these fish single rays of the dorsal fin are longer than the remaining ones. This was felt not to be attractive for a long time and the cross was also excluded from competitions. But in Asia people saw the things different. They continued developing the cross and finally the result was a fish in which the extraordinary large simpson dorsal had wavy structures along the edge. The breeders named the new sport „broccoli“. We now have received for the vey first time some of these swordtails, bred on red albinos. The red albino sport in X. hellerii is called the „Vienna cross“.

Chilatherina sentaniensis

10. August 2017

110 yeras ago – 1907 – the German-Dutch scientist Max Weber described freshwater fishes from New Guinea, which have been collected by a scientific expedition to the island by the Netherlands in 1903. One of the new species was a rainbowfish. Weber named it Rhombatractus sentanienis. Nowadays we know that fish under the name of Chilatherina sentaniensis. The specific name was chosen after Lake Sentani, elevation 75 m over sea level, where the type specimens have been collected. Later expeditions to the lake showed that the species can be found rather in the affluences of the lake than in the lake itself.

The introduction in the hobby appeared much later and until kow this attractive fish is seen only sporadically in the trade. We can offer the fish since 2013 from time to time. As in most species of rainbowfish one has to be a bit patient until the animals show their full splendid coloration, but from the moment on they do the patience is more than rewarded. For more informations on the species please see http://www.aquariumglaser.de/en/fish-archives/chilatherina_sentaniensis_en/

Apistogramma sp. Marandu

8. August 2017

We received from Peru for the very first time this new, interesting and beautiful species of Apistogramma; sadly no further information on the origin is available. As the new fish cannot be applied for sure to an already described species, we simply adopted the name the exporter gave to the fish.

Marandu belongs to the closer relationship of Apistogramma moae. A. moae is a member of the A. eunotus complex that comprises several similar species, among them A. eunotus and A. cruzi. Very obvious in A. sp. Marandu are the very conspicious horizontal stripes along the belly and the blueish shining bands that accompany the primary stripe; the latter is shown as a series of single spots most of the time.

Apistogramma sp. Marandu is for sure a very interesting and beautiful novelty and we are proud and happy that we could manage its first importation now.

Glyptoperichthys scrophus

4. August 2017

The genus Glypterperichthys (Sailfin plecos) is represented in the hobby mainly by thetwo species G. gibbiceps and G. joselimaianus, because both species have a very attractive coloration. Both are bred in large numbers in Southeast Asia and so they are almost anytime available for moderate prices. A rarity is G. scrophus, the rhino sailfin pleco from Peru. Although this species has no pretty coloration it is a fascinating look, not at least due to the large nasal lappets. P. scophus are peaceful fish. They feed inter alia on algae and so they are not only nice but also useful. The rhino pleco attains a length of about 30 cm and so it should be kept in larger tanks, likewise its better known congeners.

Guppy Magenta Tuxedo

4. August 2017

The breeders and farmers of ornamental fish in Sri Lanka still suffer from the catastrophal rains some weeks ago. Nevertheless they supply us with wonderful guppys and other livebearers, for example the beautiful Guppy Magenta Tuxedo. We have this strain from Sri Lank since 1998 in stock. All customers that order now bred fish from Sri Lanka do not only order most beautiful and healthy fish, but also support the many families that need the income from breeding ornamentals and help them to rebuild their destroyed facilities.

Melanotaenia australis

2. August 2017

One of the species of rainbowfishes with the longest aqurium history is the dwarf rainbowfish, Melanotaenia maccullochi. It reached Europe as early as 1934 and is kept and bred since then. However, if we order nowadays M. maccullochi from Indonesia we do not get this species, but another one which has only a rough similarity with M. maccullochi: M. australis. M. australis has been considered to be a subspecies of M. splendida for a long time. It is distributed in northern Australia. The variety with the pretty red fins that is spread in the hobby currently looks most similar to the form from the Sale River in the Kimberly region, state of Western Austalia. We can offer this species both as imports from Indonesia (bred fish) as well as German bred ones. It attains a maximum length of about 11 cm.

For our customers: the fish have code 427104 and 427123 (selective bred „Super Red“) on our stocklist. Please note that we exclusively supply the wholesale trade.

Polypterus palmas

31. July 2017

We received once more from Guinea the comparatively small (20-25 cm) and very pretty Polypterus palmas. Currently our fish are 10-12 cm long. Formerly the species has been splitted in several subspecies, but this seems not to reflect the real situation. Two of these subspecies have been recorded from Guinea, namely P. p. palmas and P. p. buettikoferi. Both are regarded to be full species on their own currently. P. buettikoferi can be recognized by the much broader lateral bands.

For our customers: P. palmas has code 164502 on our stocklist. Please note that we exclusively supply the wholesale trade.

Ammocryptocharax elegans

28. July 2017

There is probably no other species of freshwater fish that has such a bilious green coloration as it is shown by the 4-5 cm long ground characin Ammocryptocharax elegans. We were able to import a few specimens from Brazil. However, one should know that these fish can change their coloration very fast and in case the fish are concerned they can become camouflage brown in a glimpse. One should keep these fish in planted aquaria, for field studies showed that they have their green colours only when they can sit on submerged plants.

Moenkhausia agnesae

28. July 2017

We received once more the fantastic Moenkhausia agnesae from Peru. This is a larger species that can be kept ideally along with cichlids and catfish. Maximum length reported from M. agnesae is about 8 cm.

Formerly this species has been often confused with M. simulata. However, the horizontal stripes in M. simulata are all black, whereas in M. agnesae these stripes are reddish in the upper portions of the body.

Channa bleheri

27. July 2017

Currently is the import season for one of the most beautiful species of snakehead, the rainbow snakehead (Channa bleheri) from the state of Assam in India. The species is not only very colorful, but also stay comparatively small (at least in comaprison with some other snakeheads), namely 15-20 cm. Moreover this species is – again in comparison with other snakeheads – rather peaceful.

Neverheless this species is recommended only for experienced hobbyists, for C. bleheri is a subtropical species and lives in higher altitudes. Here it can become pretty cool at times. Experience has shown that the fish need cool periods from time to time to stay healthy over years and for breeding.

In respect of feeding C. bleheri is not very demanding. Insects and their larvae are best choice, the fish also like earthworms. One should be careful if life feeder fish are offered, for they often carry diseases and can infect the snakeheads.

Rainbow snakeheads are biparental brood carers. They egss are lighter than water and swim on the water surface wre the male concentrates them in a kind of raft. Both parents take care for the fry.

Atractosteus spatula

24. July 2017

The Alligator gars are so-called living fossils. They developed about 100 million years ago in the upper Cretaceous and haven´t changed much since then. Currently two genera live in the New World, namely Atractosteus (containing three species) and Lepisosteus (four species).

The members of Atractosteus can reach about 2 m in length (formerly they are said to have reached even 3 m, but formerly everything was better ;-)) and are thus the largest recent members of the Alligator gars. The three species are very similar to each other and differ only in details which are not observable from outside. Our specimens are currently about 8-10 cm long and have been bred in Indonesia. We believe the breeders regarding the identity of the species as we have no opportunity to verify or falsify this.

Among the ancient features of the fish are the very strange bony scalation and the remains of a “tail” in the upper half of the caudal fin, which is clearly visible in our baby fish. Gars do not breath only via gills, but also via the swim bladder which serves as a lung. So they can survive even in very oxygen-poor water.

Gars feed exclusively on fish, but can be easily accustomed to feeding by forceps. Against conspecifics and other species of fish the gars are absolutely peaceful as long as they do not serve as food. Alligator gars are gorgeous animals for large show aquaria.

For our customers: the fish have code 848131 on our stocklist. Please note that we exclusively supply the wholesale trade.

Lexicon: Atractosteus: means “arrow-bone”. spatula: means „short sword“, referring to form of the snout. Lepisosteus: means “bone-scale”.

L 128 Hemiancistrus sp. or Ancistrinae gen. sp.

23. July 2017

Many L-numbers have received correct scientific names in the meantime; not so the „Blue Phantom“, which ist stil undescribed. Currently most keepers tend to place the species in the genus Hemiancistrus, but this is not confirmed. It is also possible that the fish will have to be placed in a new genus (Ancistrinae gen.sp.).

We obtained very nice, 14-16 cm long wild collected specimens from Venezuela. The species can grow still a bit larger, at least to 25 cm. In the aquarium it requires large sandy open spaces as well as many caves and hiding places. The species has been bred already in captivity. It has the typical breeding behaviour, eg is a cave brooder. The fish prefer to spawn in caves that are open only on one side.

Trichopsis schalleri

23. July 2017

Schaller´s Croaking Gourami is sadly only very occassionally available in the trade. The very pretty fish originates from central Thailand; it attains a length of about 4 cm. So it becomes larger than the Croaking Dwarf Gourami (Trichopsis pumila, 2,5-3 cm), but stays smaller than the common Croaking Gourami (T. vittata, up to 6 cm).

T. schalleri are very undemanding fish that are ideal inhabitants for community tanks with small, peaceful fish from Southeastern Asia, like Rasboras. In contrast to many other labyrinth fishes the males prefer to build the bubble nest under broad leaves, in caves or so instead on the water surface.

Trigonostigma somphongsi

19. July 2017

The Siamese Dwarf Rasbora (Trigonostigma somphongsi, formerly Rasbora somphongsi) has been described scientifically in 1958 on the basis of specimens that were imported by the ornamental fish trade by the end of 1957 from Thailand. So the exact type locality was unknown from the beginning. In the original description nothing but “Thailand” was mentioned, later, in the more exact scientific description, Meinken wrote that they originate from “southern Menam (Thailand)”.

In the past 20 years the species was thought to be extinct in the wild. In the entrance in the international Red List the author (C. Vidthayanon, 2013) names as area of distribution the basin of the Mae Khlong near Ratchaburi in central Thailand. The species could not be found there anymore due to habitat destruction. The only reason, why the species was consideed as “critically endangered” and not as “extinct in the wild” was the fact that every now and then single specimens were spotted among mixed catches of other ornamental fish species. However, it was not known where these animals had been collected. It was clear: the species still exists! But nobody knew where…..

Now it was finally possible to rediscover the habitat of the fish in the wild again! And we were able now to import successfully some extra large and extra beautiful specimen! Of course collecting small fish in the wild has no influence on natural populations at all. In contrast: it was only due to the interest of enthusiastic hobbyists the the species could be re-discovered again. So conservation acts become possible only now. One can only hope that the authorities do not regulate the trade with live animals (which is completely senseless, as everybody nows, for the trade with live specimens is not a serious treat for wild populations of small fish at all), but hopefully protected areas will be build up. Here the fish should be allowed to be collected, but the nature in its whole would be protected.

Keeping the charming animals in the aquarium is completely undemanding. The fish become only 2-2.5 cm long. Like all the close relatives of the fish (eg the harlequin barbs Trigonostigma heteromorpha, T. espei, and T. hengeli) they spawn on the underside of broad plant leaves. T. somphongsi prefers to live in schools, but for spawning the pairs most often separate themselves from the conspecifics. The males even defend a small spawning territory for a short time. So-called V-tanks are ideally suited for the extensive breeding of this species. Here young fish can be usually separated on a regular basis.

The list of species of ornamental fish that have been discovered by hobbyists and the ornamental fish trade is much enriched by this charming fish. Hopefully it can be also placed on list of species finally safed from extinction, too. We hope that many hobbyists show interest in that fish and ask for it in the pet shops. This would maybe even make a commercial breeding possible, another important step for protection of the species.

Apteronotus albifrons WHITE

17. July 2017

The Black Ghost (Apteronotus albifrons) is a most beautiful and elegant knifefish from South America. The species has a very wide distribution, wild collected specimens most often come from the Orinoco (Colombia and Venezuela). However, the up to 50 cm long species is also bred since many years in Indonesia on a regular basis.

The mode of swimming this species performes is uncomparable. There is no thinkable manouvre that cannot be figured by the species, may it be straight on, backwards, head up or head down, upside down or upside up.

First we obtained in 2008 a white sport of the Black Ghost from Indonesia. Now we were able once more to get these interesting animals, this time they are bred in Europe. They don´t differ at all from the wild type fish in respect of elegance and swaggering (these fish fight for their position in the hierarchy with mouths wide open; in this position they try to push away the contrahent), but they appear even more than their black ancestors in a ghosty way…

Aplocheilus lineatus “Gold”

14. July 2017

The golden sport of Aplocheilus lineatus is very popualr in the aquarium hobby and the only member of the genus that can be found on a regular basis in the petshops. The reason for that is quite simple: the golden sport exhibits even as a small juvenile (3-5 cm length) already the attractive coloration, while wild coloured Striped Panchaxes of that size have still a dull grey colour. 

Aplocheilus lineatus is one of the few species of killifish that are well suited for a community tank. They can be properly fed with dried food and invigorate the upper part of the water column. However, one should keep in mind that A. lineatus can grow to a length of about 10 cm. Larger Striped Panchax feed also on small fish. So one should choose only fish larger than 5 cm as tankmates to avoid this. A. lineatus can live for many years in the aquarium. Like all species of that kind they are excellent jumpers. So the keeper has to ensure that the tank is perfectly covered.

Hyphessobrycon eques wild

14. July 2017

The Serpae tetra is one of the most popular tetras at all. This is doubtless due to its intensive red coloration. In respect of the behaviour one cannot trust them too far. They have the nasty tendency to bite off pieces of finnage from other fish, also from conspecifics.

 

From a scientific point of view the Serpae tetra is subject of a controversial debate that lasts already for more than 50 years – and still no satisfying solution has been published yet. How many species cover behind the common name of „Serpae tetra“? And what is the correct scientific name for them? So hobbyists interested in tetras will for sure be happy that we were able to import now some wild collected specimens. They originate from the surroundings of the city of Cuiabá in the state of Mato Grosso. Currently these animals are about 2 cm long and thus only half grown and not in color yet, but very healthy and lively.

Apistogramma atahualpa

12. July 2017

Before its scientific description this beautiful species of dwarf cichlid was known in the hobby as the „Sunset-Apistogramma“. And in fact the body coloration of a female during brood care reminds one in a sunset. The scientific name, atahualpa, refers to the last great ruler of the Inka empire: Atahualpa. He was captured by the Spain Pizarro in 1532 and in 1533 executed; this was the sunset of the Inka empire.

Currently we obtain beautiful wild collected specimens of A. atahualpa.

Monostichodus mesmaekersi

10. July 2017

For the first time ever we can offer this pretty and very interesting tetra from the Congo. The species is practically unknown among aquarists. The genus Monostichodus (formerly: Hemistichodus) belongs to the relationship of the subfamily Ichthyborinae (fin eaters). Many members of that group are specialized fish that feed almost exclusively on parts of fins that they bite of from other fish. At least M. mesmaekersi seems not to do this. We accompanied fantail goldfish, bettas, killifish, and knifefish with the Monstichodus, but the fins of all tankmates stayed unharmed as well as the fins of conspecifics.

They only report known to us about keeping the fish says that they proofed to be scale-eaters. We can neither agree nor deny this. What we can say is that the fish listed above also weren´t attacked for eating their scales. In our tanks the fish feed on live food, basically live bloodworm. The maximum length of M. mesmaekersi is about 6 cm. It is very interesting that every individual fish seems to have a slightly different pattern on the caudal fin. In any case this beautiful tetra is a challenge for every enthusiast that likes to be a explorer. The fish are not shy at all and their behaviour is much alike that of pencilfishes (Nannostomus) from South America.

Channa harcourtbutleri

6. July 2017

We obtained some specimens of this only very rarely offered snakehead from Burma. The species is a very close relative of Channa gachua. In fact, it has been considered to be a mere synonym of C. gachua for a very long time. But Ng, Ng & Britz could show in 1999 that C. harcourtbutleri is a valid species. However, both species look very similar. C. harcourtbutleri has a narrower head and (sadly this is mood-dependend not always visible) a dark marbled throat (uniform in C. gachua). Moreover, in juveniles of C. harcourtbutleri an ocellus in the dorsal fin – typical for juveniles of C. gachua – is missing. There are further minor differences in the pattern, but due to the extreme mood-dependend change of coloration in snakeheads these differences are of no use for identification purposes. One should also keep in mind that it is more than likely that many populations and described species currently places in C. gachua will proove to be species on their own in the future, so it is very difficult to speak of a typical pattern and coloration in C. gachua.

Channa harcourtbutleri occurs in Burma in higher elevations; here it can become pretty cool. So it is better to keep that species not the whole year through at high, tropical temperatures. Regarding the water the fish is very undemanding, but very soft and acidid water should be avoided. The common length of C. harcourtbutleri is between 8 and 15 cm, the largest specimen known so far was 18.5 cm long (all measurements given in standard length, without the caudal fin). The photographed specimens have a standard length of about 11 cm (male) and 9 cm (female) and are obviously sexual ripe.

We have no knowledge of a detailed breeding report, but it is very likely that there are no majaor differences to that of C. gachua, which is a biparental mouthbrooding species.

Carassius auratus Oranda Panda

3. July 2017

If one listens to the breeders the black and white goldfish are called „magpie goldfish“, animals with telescope eyes ae called „demekin“ and the fish with a double, but compartively small tailfin are „fantails“. An oranda, on the other hand, is a hooded fish in the language of the breeders. But honestly: who would call this nice pandas we obtained recently „magpy demekin with fantail“? Oranda panda sounds much better, doesn´t it?

 

This sports isn´t easy to breed. We have only one supplier on a regular basis and even he cannot satisfy all needs anytime. Each individual fish looks a bit different. There are even specimens in which the white part of the coloration is missing. In that case the fish look similar to the Black Moor (a black demekin variety), but nevertheless different. 

For our customers: the fish have code 817499 (3-4 cm) and 817500 (4-5 cm) on our stocklist. Please note that we exclusively supply the wholesale trade. Available in limited numbers only.

Trichogaster leerii Wild

30. June 2017

For the first time we obtained wild collected pearl gourami from Thailand. This is worth mentioning for several reasons. First, it is very ambigously discussed in the scientific literature wether the species occurs in Thailand at all; twice: the wild populations of the pearl gourami are declining terryfing fast, for the species is strictly adopted to blackwater (collecting the fish for or the trade has no impact on natural populations); and finally we have even good informations where the fish were collected. They originate from Narathiwat province near the city of Su-Magi Kolok. At this place usually the glass catfish (Kryptopterus vitreolus) is collected.

Initially the new arrivals looked very similar to their bred cousins. But a closer look showed an interesting difference: in the wild females the back has almost not pearl-spots! Currently the fish are something larger than half-grown (6-8 cm).

Amphilophus xiloaensis

30. June 2017

In the lakes of Nicaragua a group of cichlids evolved, which is very interesting from a biological point of view: the Midas cichlids. Formerly they were classified only in two or three variable species within the catch-all genus Cichlasoma: Cichlasoma citrinellum, C. labiatum, and C. zaliosum. Nowadays they are placed in the genus Amphilophus.

These fish are in the focus of several scientific research groups. These cichlids have settled several small satellite crater lakes from large lakes (like Lake Nicaragua) in different times. As these small crater lakes are closed biotopes one can study perfectly the mechanisms of speciation in the Midas cichlids. As a consequence recently a number of new species has been described: in 2002 three new species (A. amarillo, A. sagittae, and A. xiloaensis), in 2008 three additional species: (A. astorquii, A. chancho, and A. flaveolus), and finally in 2013 two new species (A. tolteca and A. viridis). However, one can expect even more species descriptions in the future.

We now have for the first time German bred A. xiloaensis in stock. They are typical Midas cichlids. The legend of king Midas says that a wish was fulfilled for him. Everything he would touch would become gold. Soon after king Midas died almost of starvation and thirst, for all the food he touched also became gold… Midas cichlids are famous for their tendency to change the regular striped coloration in a uniform (golden) – this color can be rather white, yellow, orange or red –  oder blotched coloration. In the wild, one can find striped pairs, mixed pairs, or pairs that are formed from two uniform or blotched animals. This is a very interesting phenomenon that is not understood yet. Among our fish are also all the three varieties.

Midas cichlids become large (15-35 cm) and are quarrelsome. One should keep them in the largest tanks possible and only in company of very robust fish. Midas cichlids usually live in pairs and are biparental open brooders.

Chitala blanci

28. June 2017

The Asian featherbacks, which have a well developed dorsal fin, have been placed in the genus Notopterus for a long time. Nowadays the genus Notopterus is seen monotypic (it contains only the single species N. notopterus) and the high-backed forms have been placed in another genus, namely Chitala.

Currently we have the very attractive species Chitala blanci in stock. This featherback, which can attain a maximum length of about 120 cm, originates from the basin of the Mekong river in Thailand, Laos, and Cambodia. The fish are gorgeous inhabitants for large aquaria. Chitala blanci prefers waters with a strong current and avoids quiet water or swamps.

All species of Chitala are predatory fish that have to be fed with beefy (frozen) food. Of course small fish are also eaten. The sexes cannot be distinguished externally. Against conspecifics and other tankmates that cannot be eaten, featherbacks are very peaceful. During breeding season the fish form pairs and spawn on rocks, wood etc. The spawn is guarded by the parents.

Chitala species are able to breath atmospheric air when necessary. So they can survive even in oxygen-poor water for quite a long time. This makes the much sought for market fish in the countries where they occurs. However, the flesh is full of small bones, so the meat is usually chopped, pressed through a sieve and used for meatballs.

Synodontis batensoda

26. June 2017

There does exist a good number of species of Synodontis that tend to swim upside down. The best known species is without any doubt the upside down cat, Synodontis nigriventris from the Congo. Now we were able to import the very rarely offered Synodontis batensoda from Nigeria, which shows a similar behaviour.

It seems to be quite unimportant for the fish in which position it swims actually. But one can see from the very dark coloration of the belly that the upside-down postion is very often used. Species of fish with a “normal” swimming behaviour have light bellies, so they do not contrast much with the sky. Many predatory fish hunt from below, so this coloration is necessary.

S. batensoda attains usually a length of about 25 cm (maximum size recorded is about 50 cm) and should be kept in larger aquaria. The species is quite social and should be never kept alone. S. batensoda will eat small fish, but is usually very peaceful against larger, other species. Formerly S. batensoda was placed in the monotypic genus Brachysynodontis.

Dimidiochromis strigatus

23. June 2017

The genus Dimidiochromis comprises currently four accepted species. Only one of them, D. compressiceps, is found in the trade on a regular basis and has become an ornamental fish so far. D. strigatus can still be considered a rarity in the trade. We have the species stocked now for the first time, our fish are German bred ones.

All species of Dimidichromis are predators that feed in the wild almost exclusively on small fish. In the aquarium they feed readily on any usual fish food. These cichlids do not live in rocky shores, but among reed and underwater weeds like Vallisneria over soft bottom. These predators do not inhabit territories outside the breeding season and thus they can be considered as very peaceful fish as long as accompanying fish are too large to be eaten. One should never choose the always hectic and aggressive rock cichlids from Lake Malawi (Mbunas) as tankmates, for they would be a continous disturbance for the calm and cautious Dimidiochromis.

Dimidiochromis strigatus attains a maximum length of about 25 cm. As almost all cichlids from Lake Malawi it is female mouthbrooder. The species occurs not exclusively in Lake Malawi, but also in Lake Malombe and the River Shire that connects the two lakes.

Misgurnus anguillicaudatus

23. June 2017

We received beautiful weather loaches via Hongkong. The genus is characterized by the existence of ten barbels around the mouth. The funny name „weather loach“ was given in medieval times, when these loaches were kept in captivity as weather prophets. These fish breath not only via gills but have an additional breathing technique. When the oxygen content of the water is low the loaches take air from the water surface and press it through the intestine. During that way the air is deprived from the oxygen. When the air pressure is sinking before bad weather, stagnat waters with a high amount of dirt – typical habitats of Misgurnus – begin to stink, because the oxygen content of the water sinks. Now the weather loaches become nervous and often come to the water surface to take a breath. In clean aquaria this effect doesn´t appear, so the fish are of no use as weather prophets there. Weather loaches become 15-20 cm long.

Misgurnus are very peaceful and have an anormous tolerance for water temperatures. They bear – over the year – temperatures between 4 and 30°C. Freshly caught fish are pretty sensitive, what is typical for fish from waters with a high content of organic waste, but once they have adopted the live in our clean aquaria they are hardy and long living inhabitants.

Misgurnus anguillicaudatus originates from China and can survive here in Central Europe the whole year through under outdoor conditions. So it is important to take care that these fish cannnot escape.

Iriatherina werneri

19. June 2017

Currently we have wonderful, fully grown specimens of the Threadfin Rainbowfish in stock. Like a butterfly its wings the male Threadfin Rainbowfish flaps its first dorsal fin during courtship. The males can be easily recognized by the long filaments of the second dorsal and the anal fin. The tender species attains a maximum length of about 5 cm.

There is hardly another aquarium fish as peaceful as this one. One must never keep I. werneri in company with rough behaviour, the Threadfin Rainbowfish will not survive under such conditions. In respect of water chemistry the Threadfin Rainbowfish is flexible. It thrives well in a pH of 5.5 to around 8.0 (BUT: be very careful when adopting the fish to new conditions, it is extremely sensitive against sudden changes!) and soft to medium hard water. The water temperature should be slightly higher than usual, about 25-29°C. But the most important factor is the correct feeding. These fish have a very small mouth. Food particles must be small, too! Best is living brine shrimp nauplii, but I. werneri feeds also on very fine dry food, micro, vinegar worms, rotatoria, cyclops (this can be frosted, too), etc.

Who is willing to fulfil the demands of that fish and also adds some peat, alder cones, or dead leaves in the tank will be rewarded by beautiful and fascinating looks.

Brevibora dorsiocellata

17. June 2017

Once more we were able to import this beautiful dwarf rasbora in good numbers. Al large school of them is a fascinating look!

The Eyespot Rasbora, Brevibora dorsiocellata, is a well known, classical aquarium fish. Sadly the species became almost forgotten in the 1980ies. It was Mr. Takashi Amano from Japan who was responsible for the comeback of the species. Amano often used a large school of B. dorsiocellata for his stylish tanks – a real eyecatcher!

The genus Brevibora has been separated in 2010 from Rasbora. Currently four species are known, but sadly in recent new descriptions serious mistakes have been made, so the names will change in near future again. For that reason we use the name that is best known in the hobby – Brevibora dorsiocellata.

Eyespot Rasboras are peaceful and undemanding fishes that can be kept even by beginners in the hobby. There is only one point that should be mentioned: the fish look best (most probably because they feel safe) when kept in larger schools, starting with 10 specimens – the more the better.

Brycon hilarii

12. June 2017

Every year comes a season for one of the most wanted fish or large show aquaria: Salminus maxillosus. And every year we have to look wether the ordered young fish really belong to that species. The Salminus are large (usually up to 60 cm, sometimes reaching even 1 m in length) predatory fishes hat feed almost exclusively on other fish. They imitate a harmless plant eating tetra: Brycon hilarii. In the schools of Brycon hilarii the young Salminus can easily come close to their prey. This is called „aggessive mimikry“. The Brycon is also a large fish that usually attains a length of about 40-50 cm. All in all: Salminus and Brycon look very much alike in respect of coloration.

Yesterday the first „Salminus“ import of the year from the Orinoco river arrived. All fish are Brycon hilarii. Luckily we have made pictures of Salminus of a similar size last year, so we can compare. In the internet a lot of picture are pblished under the name of Salminus maxillosus that in fact show Brycon hilarii. For all that want to compare with their own eyes: here are pictures of a Salminus (http://www.aquariumglaser.de/en/fish-archives/salminus_arrived__en/)

Brycon hilarii is a comparatively peaceful fish. Of course it will not be able to withstand to use a very small fish as an appetizer, but basically it is a plant and fruit eating species. Among conspecifics it is very peaceful, in contrast to Salminus which can be quite quarrelsome. 

The correct scientific name of our imports is not easy to apply. In the beginning of 2017 a scientific revision of the genus Brycon was published. According to that there are four species of Brycon with a dark band in the caudal fin: B. orthotaenia, B. hilarii, B. whitei, and B. polylepis. Of those only the two latter have a natural distribution in the Orinoco, but both species look totally different from our imports. B. whitei has a distinct dark band all over the body, and B. polylepis has a totally different shape of the body (much more slender than out fish). B. orthotaenia looks very much alike our fish, but B. orthotaenia is endemic in the Rio Sao Francisco. So we stay with the name of Brycon hilarii, although this species is recorded as occuruing naturally only in the Amazon river and the Paraguay river, but it is bred and stocked as a food fish in many areas. Maybe ongoing research will show that our fish may belong to another species.

Another new sport of fighting fish: Fancy Dragon Pla Kat

9. June 2017

Fighting fish are absolutely popular currently. The splendid colours, the easy breeding, the interesting behaviour and the unproblematic keeping are the reasons. Against other fish than conspecifics Betta splendens are usually completely peaceful; the only general exception are fancy guppys, as these are often erronously taken for male fighting fish and attacked.

Until now the development of a long dorsal fin (this is a mutation) was bound to another mutation, the splittail. In splittails the tail fin is parted in two. So far splittails are bred only on veiltail varieties. It is necessary to know that the gene for „veiltail“ is dominant against the shorttail gene. So the breeder has to have a great deal of knowledge of genetics to breed shorttailed splittails. Shorttailed fish are generally named as pla kat. The Fancy Dragon Pla Kat that appeared now for the first time in the market has the long dorsal fin of the splittail, but a different shape of the caudal fin. The latter is rather a halfmoon, most probably because splittails are not very popular in central Europe. However, there are folds in the caudal fin, maybe a heritage of the splittail ancestor.

Each individual fish of the Fancy Dragon Pla Kat looks different. But in respect of the instinctive fighting behaviour they are typical fighting fish. The fight starts with a sinking of the bottom of the mouth and spreading of the gills and opercula; after that the fish start lateral displaying with maximum spread fins. The ventral fins are used like flags in that state of the fight. Only after a good while the fish start to a fight to damage the competitor. This begins with „empty“ bites against the fins. At that stage of the fight we separate the photomodels to avoid any hurts. If we would not do so the fish would start to bite in the fins (the Thai idiom pla kat means „biting fish“) which can look really destoyed after some time. However, the fight usually does not lead to the death of one of the competitors and the fins regenerate completely. Nevertheless it cannot be recommended to keep more than one male per tank.

Rhynchodoras woodsi

9. June 2017

Only very rarely members of the enigmatic genus Rhynchodoras (family Doradidae) appear in the ornamental fish trade. It is believed that these fish live in the very riverbed where collectors of ornamental fishes usually do not fish at all. All species of Rhynchodoras have a strange appendix on the jaw that looks like a share; the function of this structure is unknown.

Three species are currently recognized in the genus, none of them is reported from Peru so far; our fish are from Peru. It is nevertheless very likely that our specimens belong to  Rhynchodoras woodsi, a species described in 1976 from the Rio Pastaza basin in Ecuador. It is reported so far (despite Ecuador) from the Amazon basin in Brazil (not in the rivers Xingu and Tocantins) and Guyana. Maximum length reported is 10.5 cm, our fish are currently 3-4 cm long.

Corydoras elegans “Peru”

7. June 2017

We received a small number of this pretty cory from Peru. It was shipped under the nice name „Corydoras Brilliante“. In fact the dark longitudinal band of the fish shines in a bright emerald green when the reflecting light comes in the correct angle, but all in all the fish is „only“ a local variety of Corydoras elegans as it currently understood; C. elegans has a very wide distribution in the Amazon basin. However, on the other hand, a good number of doubts exist that all the „varieties“ applied to C. elegans really represent only one species.

A close look shows differences in coloration. The Peruvian fish have – in contrast to specimens from Brazil, the type locality of C. elegans is near Tefé – a short dark band in the neck that end below the dorsal fin. This shot band is well separated from the usual longitudinal dark band along the complete body that is so typical for C. elegans. This coloration of the Peuvian fish fits perfectly to the pictures made in the 1940ies from a species named Corydoras pestai. The scientific description of C. pestai bases on a specimen imported by the aquarium trade and exhibited with some conspecifics in the zoological garden of Munich, Hellabrunn. The type locality is unknown, and the type specimen destroyed during a bombing attack in WW2.

Nowadays Corydoras pestai is considered to be a synonym of C. elegans, but due to the lack of a type specimen this synonymization is not very certain. Maybe the „Brilliante“ is a C. pestai? Anyway, we name them Corydoras elegans „Peru“…

Wallaceochromis signatus

6. June 2017

Prior to its scientific description this species as been known in the hobby under the names of Pelvicachromis sp. „Bandi1“ or „Guinea“. The species can be always easily recognized by the black tailspot of the female. Usally the female has only one black spot in the dorsal fin; the fact that the photomodel from our current stock has two spots in der dorsal bases on an individual aberration. The many spots in the dorsal fin in the male is also species-specific for Wallaceochromis signatus.

The cichlids love to dig! One should keep all these dwarf cichlids always in a tank that contains at least in part a soft sandy bottom. Digging in the sand serves not only to let the fish feel comfortable, but it is also very healthy for them.

Pygocentrus piraya

3. June 2017

The „real“ piranha, Pygocentrus piraya, is restricted to the river system of the Sao Francisco in southern Brazil. It is a up to 30 cm long species, which is characterized by its deep red breast and the mighty jaws when it is fully grown.However, even juveniles display a very attractive coloration.

Most piranha species belong to the genus Serrasalmus. Externally Pygocentrus and Serrasalmus are very similar, but the behaviour of the members of the two genera is completely different. All Serrasalmus are fin eaters and solitary fish whereas all three Pygocentrus species (P. caribe, P. nattereri and P. piraya) are schooling fish.

This means that P. piraya should be kept in real big aquaria, as it becomes a large fish and must be kept in groups. When they reach maturity, pairs build up small territories (places around large plants are most wanted). They dig out spawning pits by hitting away the gravel with the caudal fin and defend this against other fish. Only the male defends eggs (many thousands) and fry. The brood care ends when the young become free swimming.

Usually no piranha will attack a human being. Nevertheless you should keep respect as the fish have razorsharp teeth and can give really heavy bites. There is only real danger when the aquarium is too small for the fish and they cannot get out of the way or during feeding times, as by chance the piranha can take the keeper’s finger for food by mistake.

All in all P. piraya is a gorgeous fish for show tanks where it can also show its faszinating and highly developed behaviour.

Hyphessobrycon herbertaxelrodi Wild

3. June 2017

Wild collected black neon tetra? This is extremely rare, even in our company. The black neon tetra is one of the most often traded ornamental fish at all and much sought for. So it is available any time in any number as bred ones, even some artifical sports have been bred, like „smoke“ or „albino“. These bred fish are also always much cheaper than a wild collected fish can be. So we are very glad that we now managed a small importation of wild collected animals. The species originates from the Rio Paraguay basin in Brazil and Bolivia.

Pelvicachromis roloffi

1. June 2017

The maybe rarest of all dwarf cichlids of the genus Pelvicachromis is P. roloffi. So we are very glad that in our current import from Guinea some specimens were included. This species depicts in almost all different moods a clearly visible, horizontal band. The females are – as usual in Pelvicachromis – the more colorful fishes. P. roloffi is a small species. Males hardly grow larger than 8.5 cm, femals always stay smaller.

Wallaceochromis humilis „Kasewe“

30. May 2017

Finally we were able again to organize an import of – inter alia – dwarf cichlids from Guinea. Formerly all these fish were placed in the genus Pelvicachromis, but the species humilis, signatus, and rubrolabiatus have been transferred to the newly described genus Wallaceochromis in 2016. The naming of the different local populations of these fish is somewhat confusing, as by far not all specimens collected together look the same phenotypically. This time we mainly obtained the local variety „Kasewe“. The photos show specimens from our current stock. But we also received other varieties which we plan to show you in the next days.

Wonderful bred Altum angels available!

10. May 2017

The Altum angel (Pterophyllum altum) is extremely demanding during the rearing period. If the breeder makes even a minor mistake in respect of water quality or the food this results at once in a life-long deformation of the fish. These gnarled ventral fins, crooked anal fins or defects of the operculum are not heritable; so it is possible to get good offspring from these deformed animals. But they nevertheless do not look good.

Now we are in the happy position that we can offer even two different strain of top quality bred Altums; both breeders offer real perfect fish that look as good a s wild collected ones but lack the notorious sensibility of the latter. The brood we call „Orinoco“ differ from the regular ones by the extremly long filaments especially from the dorsal fin, otherwise both strains have no remarkable differences.

For our customers: the fish have code 698303 (Orinoco) and 698402 on our stocklist. Please note that we exclusively supply the wholesale trade.

Puntius titteya „Longfin“

8. May 2017

Quite recently a new sport of the cherry barb, Puntius titteya, apperaed in the market. The fish are offered from Southeast Asia. We have imported them now for the very first time. A most intersting fact is that in this sport only the caudal fin is prolonged, the remaining fins have normal size. In all longfin/veiltail varieties of cyprinid fish that are known so far (mountain minnow, Tanichthys albonubes; zebra fish, Danio rerio; leopard danio, Danio frankei; rosy barb, Pethia conchonius; goldfish, Carassius auratus; Kkoi, Cyprinus carpio) the reaminig fins are also prolonged, not only the caudal fin. This pecularity gives the cherry barb „longfin“ a really extraordinary look.

Two new tetras from the Rio Negro region: Hyphessobrycon paepkei and H. cf. agulha

5. May 2017

In a shipment containing Hyphessobrycon socolofi (Socolof´s bleeding heart) we found an extraordinary large number of bycatches. Allmost half of the shipment were another species, obviously a close relative of H. ornatus (Rosy tetra). We took a closer look and found the the bycatches were the Goldshoulder rosy tetra, H. paepkei. This species has been described only a few years ago, the type specimens also originated from our fishhouse. Usullay onyl a few specimens could be selected from shipments of other species, but this time we had quite a good number. So we decided to assort them. A nasty buisiness, but now we were able to offer the beautiful Goldshoulder rosy tetra for the first time on a regular basis. Regarding keeping this fish: it does not differ in any respect from well known, closely related aquarium fish, like the phantom tetras or the rosy tetras.

Another new species also reached us in former times in single specimens only from the Rio Negro region. Without any doubts the animals are identical with the tetra illustrated on page 472 of „the bible of tetra lovers“, Gery´s „Characoids of the world“. The caption says „Hyphessobrycon agulha, or close to it“. In contrast to all the different varieties of tetra that look similar this one has very attractive red stripes in the caudal fin. This new tetra is also comparable in respect of aquarium demands to a very well known one, namely the Black Neon, Hyphessobrycon herbertaxelrodi.

Hyhessobrycon cf agulha

For our customers: Both species were available in limited numbers only and are sadly sold out already.

Betta splendens – real fighter Pla Kat Luk Maw

5. May 2017

It is a well known fact that the Betta splendens kept in the aquarium hobby as ornamental fish do not represent the species as it appears in the wild, but a domesticated fish. Initially this sport has been bred for combats, similar like sports of cocks and dogs. Only in the 1920ies, when supplying ornamental fish for the aquarium hobby became more and more an important economic factor for people in Southeast Asia, breeders started to select veiltailed sports and aberrant colour varieties. These fish are useless for combats.

The tradition of fish fights is still alive in many parts of Asia. Due to the high sums of money people bet here – and which lead to the ruin of many bet-junkies – these combats are under legal control, but in many areas they are also cultural property under special protection.

Here in central Europe is no interest in watching animals fighting and to bet on the winner, we are focussed on the empathy with the animal we keep. Nevertheless it is very interesting for a real enthusiast to get the possibility for studying these real fighters among the Bettas. These fish are called Pla Kat Luk Maw in Thai, which means about „biting fish of the earthen pot“. „Earthen pot“ refers to the traditional pottery vessels used for breeding the fish. One of the most astonishing facts is that almost any red is missing in the coloration of the fish. Even the skin of the gill-membranes, which are spread when the fish is in aggressive mood, are pitchblack, as the whole fish appears in highest excitation. Pla Kat Luk Maw are usually bred in blue, but sometimes also turquoise animals appear.

Channa bankanensis

4. May 2017

Many species of snakehead look very attractive as juveniles. Channa bankanensis is no exception from that rule. The reason for the sometimes extraordinary change in coloration is the behaviour. Juvenile Channa are usually schooling fish. Depending on the species they swim in close schools up to a length of 3 cm or even 15 cm. The contrasting juvenile coloration has two basic reasons: first, it helps conspecifics to identify other fish as members of the same species, and second it confuseses predators for the silhouette of the single specimen is only hard to detect in a school.

Later on snakeheads become more and more solitary fish and the coloration becomes dull. Now camouflage is asked, for larger snakeheads are usually predators that feed on small other fish.

Channa bankanensis belongs to the medium sized species that attain a maximum length of 25-30 cm. The species is a typical blackwater inhabitant that lives in the wild in waters with a very acidic character: pH around 3! Luckily the do not demand this in aquaria. Channa banakanensis is distributed in Indonesia and Malaysia.

We currently have very pretty 4-6 cm long juveniles in stock.

For our customers: the animals have code 409021 on our stocklsit. Please note that we exclusively supply the wholeale trade.

Luciosoma setigerum

3. May 2017

This barb with the extremely aerodynamic shape originates from Indonesia. Despite the size the fish can reach – up to 25 cm – the peaceful and splendid colored fish is an ideal inhabitant for a community tank with other large barbs from Asia, like Bala sharks (Balantiocheilus) or Sahyadria denisonii.

Copella arnoldi

2. May 2017

The Splashing tetra (Copella arnoldi) is very famous due to it´s unique way of spawning. The pair jumps out of the water and deposites the eggs on the underside of plant leafes hanging over the water surface (in the aquarium they often spawn on the top glass). After spawning the male guards the clutch and splashes water in regular intervalls over the eggs to avoid drying. The offspring hatches within 36 hours.

This fascinating behaviour is one of the „must have seen“ events in the life of every real enthusiast. However, one tends to forget sometimes the fact that the Splashing tetra also is a real beauty! Currently we have fully grown animals in stock. The Splashing tetra inhabits in the wild savannah creeks in the Rio Xingu basin in Brazil; however, nowadays almost exclusively bred specimens can be found in the trade.s

Freshwater pipefish from West Africa

28. April 2017

There are three species of freshwater pipefish known to occur in West Africa. They live in inland waters along the coast and have a very wide distribution. One can find these fishes from the Senegal to Angola (roughly 16°N to 18°S). The term „West Africa“ is not used here in the sense of the UN, but is meant as the whole coastal line of the continent. We obtain our freshwater pipefish from Nigeria.

From time to time we can import the largest of the three species, namely Microphis aculeatus. This pipefish becomes about 15-20 cm long. Microphis live free swimming in the water column and imitate a dead stick. Usually one can observe them in a horizontal posture. More information on the very interesting species can be found here: http://www.aquariumglaser.de/en/fish-archives/gorgeous_pipefish_arrived_from_nigeria__en/

In our current import of that species we found intermixed some bycatches of the two other known species of pipefish from West Africa. Both belong to the genus Enneacampus. This genus has been established only in 1981 and contains only these two species. In contrast to Microphis Enneacampus live more substrate orientated. Although they swim around from time to time they prefer to rest on the bottom or to crawl in caves or waterplants. The first species is Enneacampus ansorgii, a species that is already known quite well in the hobby. It is even bred from time to time. This species is quite tiny and attains a total length of about 8-14 cm. Males have been found to bear eggs with a length of 7.5 cm already. There is a comparatively large number of publications in the aquarium literature, but most of it has been written prior to 1981 under the synonym of Syngnathus pulchellus. So if one does research on the species in literature the search should include the name Syngnathus pulchellus.

We find the coloration of the second species, Enneacampus kaupi, quite spectacular. Five specimens we could pick from our Micophis import, one is bright yellow, three are brick red and one almost black. We think the these colours are due to the breeding season, because in the scientific literature E. kaupi is described as rather brown with a red belly. This species is somewhat larger than E. ansorgii, sexual activity starts at a length of 8.5-9 cm, while the largest specimen observed so far had a length of 17 cm. Both species of Enneacampus look very similar at the first glimpse, but on a closer look one can clearly see that E. kaupi has a comparatively longer snout.

Regarding keeping pipefish in aquaria: all species are quite demanding fish in respect of feeding. Without a a save source for living food it can not be recommended to try to keep them. Microphis aculeatus and Enneacampus kaupi feed readily on life bloodworm and white moskito larvae. The tiny M. ansorgii cannot swallow such large food items, they prefer small crustaceans, like Cyclops, Daphnia etc. They also accept Artemia nauplii (best: newly hatched, due to the nutrition factor). If one has to feed the pipefish regularly with brine shrimp it is best to add some salt to the water in the aquarium (a tablespoon per 10 litres of waters). This is tolerated by the pipefish and the brineshrimp stay much longer alive.

For our customers: Micophis aculeatus has code 149204 on our stocklist. The few specimens of Enneacampus have been given to a breeder, so we have none for sale. Please note that we exclusively supply the wholesale trade.

Hyphessobrycon melanostichos

28. April 2017

In our latest newsletter I made a regattable mistake: I used pictures of Hyphessobrycon cf. melanostichos instead of pictures of the „real“ Hyphessobrycon melanostichos in the post; H. cf. melanostichos differs a lot from the „real“ species in life colours. So here are now pictures of the „real“ H. melanostichos, the fish we currently have in stock. It is very interesting that in tis species the male changes a lot in coloration, as we have seen it in Hemigrammus coeruleus. This is very unusual in species of the Hemigrammus-Hyphessobrycon-relationship, in which the males usually only get a bit brighter coloration during courtship.

Hyphessobrycon melanostichos has a striking bright skyblue dorsal coloration. The species has been described scientifically in 2006 from the state of Mato Grosso in Brazil; here H. melanostichos is found in the upper reaches of the Rio Tapajós basin. The species is distinguished from all other species of Hyphessobrycon by the comobination of the following characters: „a conspicuous longitudinal broad black band, beginning on the posterior margin of orbit and reaching the distal tip of middle caudal fin rays; humeral spot vertically elongate and distinct from lateral band; and 16 to 18 branched anal-fin rays.“ (Carvalho & Bertaco, 2006)

The coloration (of preserved fish) is the same in Hyphessobrycon cf. melanostichos, but this form has 19 branched anal fin rays. Moreover in the original description of H. melanostichos a freshly preserved male is illustrated, obviously a breeding animal. The coloration of this specimen fits perfectly to the one of the mating male we can illustrate here (it is one of the parents of the fish we currently have in stock). So we have no doubt anymore that we now have the „real“ Hyphessobrycon melanostichos in stock, while the status of the H. cf. melanostichos remains the subject of further investigations.

For our customers: the „real“ Hyphessobrycon melanostichos has code 261832 on our stocklist. Please note that we exclusively supply the wholesale trade.

Tetras: top rarities, German bred

27. April 2017

We obtained from our proofed breeder three species of tetra which are hardly – if ever – available in the trade, all German bred. Hyphessobrycon melanostichos, H. nigricinctus, and Hemigrammus coeruleus. Especially H. coeruleus is now available in larger numbers (yippieh!), the remaining two species are only in small numbers in our stock.

Pseudogastromyzon cheni

25. April 2017

Now the season for the charming hillstream loaches imported via Hongkong has started. There do exist several species and we also have several species in stock currently. There is a lot of confusion regarding the identity of two species of Pseudogastromyzon, namely P. cheni and P. myersi. Both species look almost identical. And both species show a high degree of variability in respect of coloration. There is only one (known) possibilty to tell them apart for sure: one has to take measurements. The first measurement is the distance between the origin of the pectoral fin and the origin of the ventral fin. The second measurement has to be done for the distance between the origin of the ventral fin and the anus. If both measurements are equal, then the fish is P. myersi. Is distance 1 larger than distance 2 the fish in question is P. cheni. This difference can be found in both sexes. We have shown the technique of the measurements in one of the pictures accompanying this post. All individuals depicted are P. cheni.

 

To be honest, until now we looked rather for (somewhat obscure) differences in coloration to tell the two species apart. Currently we have both (?) in stock. The pictures presented here are already elder, so we plan to investigate our fish in the fishhouse in the near future once more. We are very curious what this investigation will show up!

Anyway, both species are very nice and very entertaining aquarium inhabitants. They love a tank with a lot of current, a lot of stones, and a lot of light. Like all loaches the hillstream-loaches feed on small invertebrates, but the horny lips also allow them to scratch algae from the stones. In the aquarium they readily feed on any usual type of fish food. The water temperature in the tank for these hillstream loaches sholud not climb over 24°C for longer times.

For our customers: the fish have code 448524 (P. cheni) and 445802 (P. myersi) on our stocklist. Please note that we exclusively supply the wholesale trade.

Boraras brigittae

21. April 2017

Dieter Vogt described in 1978 a subspecies of Rasbora urophthalma (please see the entry for Boraras urophthalmoides in our fisharchives: http://www.aquariumglaser.de/en/fish-archives/boraras_urophthalmoides_formerly_rasbora_urophthalma__en/) from Borneo. He named the fish Rasbora urophthalma brigittae, a dedication name in honour for his wife Brigitte. The German name is „mosquito rasbora“. This is not because the fish are as tiny as mosquitos or as red as moskitos after having a dinner, but due to the fact that there were so many mosquitos at the collecting site that fishing became a real pain.Today the mosquito rasbora is regarded as a full species in Boraras and thus the correct name is Boraras brigittae.

For our customers: B. brigittae has code 451102 on our stocklist. Please note that we exclusively supply to the wholesale market.

Danio sp. Hikari Blue & Yellow

20. April 2017

Hikari-Danios belong to a scientifically still undescribed species of Danio from Burma. The closest relative is Danio kerri. However, Hikari danios are by far more colorful than D. kerri and really beautiful fish. Keeping and breeding Hikari Danios is absolutely comparable to the very well known zebra fish, Danio rerio. Hikari danios attain a maximum length of about 5 cm.

It has been a quite long time since the last import of these pretty fish. Now we were able to get them again. By that opportunity we found that we had two different codenumbers for Hikari danios, one for „blue“ and one for „yellow“. We asked our supplier and he answered: in fact the fish have formerly been assorted in blue and yellow ones until we became aware that the blue ones are the females and the yellow ones the males…

Macrognathus aculeatus

18. April 2017

Once more we obtained from India (Bengal) wonderful Eyespot Spiny Eels. The fish are of adult size and 12-15 cm long. The only complicated thing in this species is the scientific naming. The Eyespot Spiny Eel attains a maximum length of about 20 cm and ist one of the most colourful species of all spiny eels. One should be very careful during the acclimatisation, as the fish tends to develop a fungus in small wounds, but once the fish is settled it is very hardy and long living.

Formerly it was thought that there is only one species of Macrognathus, namely Macrognathus aculeatus, with an extremely wide distribution over South and Southeast Asia. Nowadays only individuals from Indonesia are thought to belong really to M. aculeatus. The small, striped Eyespot Spiny Eel from Bengal and Bangladesh is still named „Macrognathus aculeatus“ in many books and scientific articles on freshwater fishes of the region, but it´s proper name is – according to the most recent scientific research – Macrognathus aral.

One should keep this beautiful fish in a tank with a well structured equipment – roots, stones, caves, plants – and a soft bottom. Very small fish will be eaten, but against all other fish and conspecifics the Eyespot Spiny Eels are very peaceful. Settled fish will usually accept even granulated dry food, but frozen food items (bloodworm, large Artemia etc.) should be offered, too. Eyespot Spiny Eels spawn often in aquaria; males are smaller and more dainty than the females. Astonishingly these bottom-dwelling fish prefer the roots of swimming plants to spawn in. It is most likely that this hinders the eggs to sink in the deep muddy bottom in the natural habitats of the fish where the eggs would suffer. Spiny eels do not take any further care for their eggs.

Betta simplex

12. April 2017

This small (5-6 cm) mouthbrooding species from Thailand is a very nice addition to the good assortment of wild collected Betta we currently have in stock. Betta simplex is a very close relative to the species Betta picta from Java, Betta falx from Sumatra, and Betta taeniata from Borneo. All the mentioned species share the same ancestor. The males have a broad green to blue (reddish in B. falx) seam in the anal and the caudal fin. Our B. simplex are not fully grown yet, but already sexually ripe. The males do show already what beauties they will become when fully adult. In contrast to many other mouthbrooding Betta species, B. simplex is not adopted to soft, acidic water, for the natural habitat (near the town of Krabi in the south of Thiland) is characterised by lime stone hills.

Hyphessobrycon sp. Red-Blue Peru Tetra, now H. margitae

12. April 2017

This tetra, which attains a maximum length of about 4-5 cm, is without any doubts one of the most attractive members of the tetra family. The species has been described scientifically recently under the name of Hyphessobrycon margitae. It originates from Peru, according to the exporters from the Loreto region, Rio Nanay basin. Regarding the behaviour it shows a lot of similarities to the Purple emperor tetra (Inpaichthys kerri). Sometimes H. margitae is confused with Hyphessobrycon nigricinctus, the Peruvian emperor tetra, which has, however, a much narrower lateral band.

The Red-Blue Peru-Tetra is a peaceful animal that can be kept in any community tank with other peaceful fish. We can currently offer fully grown bred specimens, but we also have sometimes wild collected specimens in stock.

For our customers: the fish have code 262153 (wild) and 262164 (bred) on our stocklist. Please note that we exclusively supply the wholesale trade.

Lexicon: Hyphessobrycon: ancient Greek, means “small Brycon”; Brycon is another genus of tetra. Inpaichthys: dedication name for the  Instituto Nacional de Pesquisas da Amazonia (INPA); ichthys is ancient Greek and means “fish”. kerri: dedication name for W. E. Kerr, at the time director of INPA. nigricintus: Latin, means “with a black band”. margitae: named in honour of the wife of the describer, Margit Zarske.

Poecilia wingei, Endler´s Livebearer „White Peacock“

10. April 2017

The breeding of the different sports of Endler´s Livebearer has become a popular branch of the hobby. There are a lot of sports, some artifical – developed by cross-breeding or selective breeding – some are different looking populations that appear in the wild. The White Peacock is such a wild type. The ancestors of the fish in the trade have been collected by Armado Pou in 2004 from the Laguna de los Patos North Lake, according to the informations available from specialized web pages. For sure the fish are now much more uniformly coloured than the animals living in the wild, but they still have their extremely lively habit and they have stayed so wonderful small and dainty. Displaying males become much darker in coloration, compared with the neutral coloration. We obtain our fish from our proofed breeder in Thailand. The matching females are also available.

Phractolaemus ansorgii

10. April 2017

Finally we were able to import again Phractolaemus ansorgii. The last importation was years ago. Sadly the fish are sold out already, but we nevertheless want to show you the interesting animals.

Formerly we obtained these fish from Nigeria, this time they originate from the Congo. In our current import obviously two colour morphs appear, a more reddish one and a more blackish one. We didn´t observe such differences in our former importations, the Nigerian ones were uniformly brownish. Sexually active males develop breeding tubercles along the flanks and around the eyes. 

These unique fishes are said to be close relatives of the Kneriidae on the one side, but they show also many relations to the bony tongues, and here especially to the butterfly fish, Pantodon buchholzi. Phractolaemus are air breathers. It s said that these fish can attain a maximum length of about 20 cm. The photographed male that clearly shows breeding tubercles – is about 8 cm long. There is almost nothing known on the natural history of these unusual fishes.

Altolamprologus calvus

7. April 2017

This cichlid belongs to the most attractive species of the family from Lake Tanganyika. It attains a maximum length of about 13 cm. Despite the lurky look the fish is one of the most peaceful species of cichlid at all. One can say as a rule: if another fish is too large to serve as food it will become simply ignored. And astonishing enough: although Altolamprologus calvus is for sure a predator in the wild it happily accepts even flake food in the aquarium…

Hemigrammus rubrostriatus

5. April 2017

Until now we were able to present this beautiful tetra – which has been described scientifically only in 2015 – to you only as a very rare bycatch (see http://www.aquariumglaser.de/en/fish-archives/hemigrammus-rubrostriatus/). But finally we managed a larger importation of that beauty from Venezuela. The fish are about 4-5 cm longer, adult and in full colour. They belong obviously to the most attarctive small species of tetra at all. The tail pattern is similar to the Head-and-Tail-tetras (Hemigrammus ocellifer and H. falsus), but the bright tailspot is blood red instead of yellow; the gorgeous red horizontal stripe is as bright as in Hyphessobrycon amapaensis and the golden-yellow belly shines like that of the Kitty tetra, Hyphessobrycon heliacus. Additional the red and white pattern of the fins is very nice in H. rubrostriatus. If a tetra would have been designed as an ideal community fish, this is it!

If it comes to the requirements of the fish: Hemigrammus rubrostriatus – we suggest Red-Stripe tetra as a common name – is as easy to keep as its congeners that live in aquaria for almost a century now. Any tap water will do for keeping. However, soft, slightly acidic water and the addition of humic acids from dead leaves, peat, alder cones, roots etc. will increase the intensity of the colours.

Corydoras sodalis

3. April 2017

We received beautiful coloured Netted Corys. The species Corydoras sodalis is quite often imported, but mostly under the completely wrong name of Corydoras punctatus. The real C. punctatus originates from Surinam, occurs hardly ever in the trade and looks very similar to the well known species C. julii and C. trilineatus. A cory that can be really easily confused with C. sodalis is C. reticulatus. Both have the same pattern and the same body shape, but in C. reticulatus always a clearly marked, dark spot is present in the dorsal fin, which always lacks in C. sodalis.

The extraordinary nice colours in our recently imported C. sodalis can possibly be due to the breeding season of the species. The closely related C. pantanalensis (formerly known as C5) also shows a very nice pattern during the breeding season. However, C. sodalis reaches onyl a maximum length of about 5-6 cm, while his cousin from the Pantanal becomes much larger. The natural distribution of C. sodalis is a large area in the upper Amazon region of Peru and Brazil. Our current import originates from Brazil.

Rhaphiodon vulpinus

3. April 2017

Rhaphiodon vulpinus belongs to the largest of the sabertooth tetras. The species can attain a maximum length of about 80 cm and a weight of up to 2.1 kg. It has a very wide distribution in South America where it is called „Biara“. This predator has, very much alike the close realtives of the genus Hydrolycus, two very long teeth in the lower jaw. With these the fish spears its prey. When the mouth is closed, the long teeth fit in a sheath in the roof of the mouth. Biaras are wonderful subjects for public or very large private aquaria. Currently we have juveniles of different size from Peru in stock. Against conspecifics and other species of fish that cannot be eaten, Rhaphiodon vulpinus is very peaceful.

Extraordinary attractive Hypancistrus debilittera (L129) arrived!

2. April 2017

Currently is the best import season for plecos from the Rio Orinoco. So we have a large number of species in stock. Among them is of course Hypancistrus debilittera, which was called L129 before it became described scientifically. This is a pretty, small species with an enormous range of colour pattern. There hardly exist two specimens that look exactly identical. The maximum size of that species is approximately 10 cm.

In our current imports almost all specimens have amore contrasting pattern than we are used to in that species. We cannot explain that phenomenon, but we really like it!

Benitochromis nigrodorsalis

2. April 2017

We can cvurrently offer a very small number of German bred specimens of a top rarity among the cichlids of western Africa: Benitochromis nigrodorsalis. This species has been described scientifically only in 2001. It originates from Cameroon and the island of Fernando Poo. Prior to the scientific descrption the fish was known as „Chromidotilapia finleyi Moliwe“ in the hobby. The species attains a length of about 12 cm.

Benitochromis is closely related to the Pelvicachromis species and can be compared regarding the aquarium biology quite good with these peaceful and colorful cichlids. In contrast to Pelvicachromis, which are cave brooders, Benitochromis are biparental, ovophilous mouthbrooders. This means that both parents take care for eggs and fry; eggs and fry are given from parent to parent several times per day. The eggs are taken in the mouth immediately after spawning (= ovophilous).

Lepidosiren paradoxus

29. March 2017

The South American Lungfish is a very interesting fish, but it has only very drab colours. The usual pattern is mudcolour, eg brownish, greyish, sometimes a bit blackish. But why should an animal that lives in swamps and feeds on snails show bright coloration? On the other hand: astonishingly enough, very young specimens, like the ones we obtained recently from Peru (6-9 cm long) are very pretty! The fish are pitchblack and have golden-yellow dots. Against conspecfics the youngsters are very peaceful. This cannot be said about the adults! Pictures of adult specimens can be seen here: http://www.aquariumglaser.de/en/fish-archives/lepidosiren_paradoxus_en/

Hemiodontichthys acipenserinus

28. March 2017

This species has been named “Pinocchio cat” in the trade due to its funny looking nose. The species represents the smallest of all mouthbrooding whiptail cats – it usually grows only to 10 cm total length in aquaria – and is thus very well suited for keeping. We currently were able to import these beautiful animals once more from Peru.

The fish are – as already mentioned – mouthbrooders, the male takes care for the eggs. We are very happy that one of our males currently bears a batch of eggs. Of course, we are a wholesaler, not a breeding station, but nevertheless this shows us that our fish really feel good, for otherwise they would not breed at all.

Wild Rams

28. March 2017

Due to the regularly offered, amazing bred sports of the Ram (Mikrogeophagus ramirezi) one tends to forget, how breathtaking beautiful the wild collected fish is already. Currently we have fully grown, wild collected Rams from Venezuela in stock. By the way: wild collected Rams become only about 5 cm long (in males), females even stay smaller, so this species is definitely a dwarf cichlid!

Megalechis thoracata „Albino“

24. March 2017

The Port Hoplo Megalechis thoracata – maybe the synonym (now invalid) name Hoplosternum thoracatum is more familar to some readers – is one of the earliest aquarium fish at all. The fish has only one real disadvantage: the maximum size, which is about 15 cm (or sometimes even larger). However, the species has a comparatively small mouth and so it fits quite well in a community tank with more robust and somewhat larger fish. Megalechis have a great fan community who calls them the „fighting sausages“.

Breeding Megalechis is very interesting, for male Port Hoplos build up a foam nest, similar to that known from anabantoids. Megalechis prefers to build it under a swimming item (breeders often use the covers of old coffee boxes, but this is hardly ever available in the wild). The male is very pugnacious while guarding the nest and will even jump in the keeper´s face if this curious person comes too close to the nest!

Until now no artificial sports became known from Megalechis. But now we obtained from a breeder an albino sport. These animals look very attractive. We wanted to make also photos from „regular“ Port Hoplos for comparison and while looking through the animals we have in stock we also found two almost black animals! This is quite astonishing after decades of keeping and breeding Megalechis without such mutations!

For our customers: the fish have code 259322 (albinos) and 250302 (regular coloured) on our stocklist. Please note that we exclusively supply the wholesale trade.

Peckoltia sp. Red Tiger L209

24. March 2017

When we imported this beauty for the very first time it was not possible to identify it as a already known species. But now there is a consensus among hobbyists that it is identical with L209. L209 is a typical member of the genus Peckoltia. The omnivorous species attains a maximum length of about 15 cm. The species originates from the Rio Madeira. In the meantime it was possible to breed the fish successful, so hopefully it will stay available in the hobby.

Stiphodon semoni

22. March 2017

Once more we were able to import one of the gorgeous gobies belonging to the genus Stiphodon. This time we most likely received Stiphodon semoni, a species that is known for a long time already scientifically. It has been described already back in 1895. The species has a wide distribution, it is known from Sulawesi, Bali, New Guinea (Irian Jaya), generally in Indonesia, in the west to the Solomon Islands. The larvae of this species develop in marine environment, so the wide distribution is not so astonishing. The adults are strictly freshwater fish that prefer clear, small streams.

The members of the genus Stiphodon are in general termed as „neon gobies“, but this fits especially for S. semoni. Keeping these fish is pretty easy, Stiphodon are very peaceful fish. They should be kept in groups. In that case they show a lot of interesting behaviour. The bottom of the tank should be furnished with round river stones of about 6-8 cm diameter, and portions of sandy bottom. Of course these current loving fish should have a good filtration in their tank. The water temperature can be between 24 and 28 °C.

Laevimon kottelati

22. March 2017

We were able to import some specimens of the freshwater crab Laevimon kottelati. This interesting an beautiful crab attains a size of about 4.5 cm Carapax-width aund existis endemicly in Vietnam. Here it has been discovered in 1998 and decribed scientifically in 2005 as a new species in a new genus. It lives amphibic in the shallow water of the bank of small rivers. The photos of live specimens we post here are to the best of our knowledge the only ones that exist.

Brachygobius sabanus Thailand

20. March 2017

We received this pretty species of bumblebee goby from Thailand. The determination of bumblebee gobies often proofes to be quite tricky; usually a big questionmark has to be set behind the names. Brachybobius sabanus has been described initially from Borneo (Sabah), our fish have been collected in Thailand. But the illustration accompanying the original description of B. sabanus fits very good for our specimens.

B. sabanus attains a maximum length of about 2.5 cm. The coloration differs a lot individually. The species inhabits pure freshwater habitats. We were very glad to observe a spawning in our facility. But we thought the eggs would suffer from fungus quite fast. When the male was defending the whitish eggs still for days we took a closer look and discovered that the eyes of the offspring were already visible in the eggs. In fact it was the white yolk sack, not fungus that made the eggs look white! Sadly the larvae hatched on weekend in the night when no one was in our fishhouse. But we think an experienced hobbyist should be able to raise Brachygobius sabanus without problems.

Mastacembelus sp. „Nargis“

17. March 2017

We could import this new discovery – a spiny eel – for the first time now from Burma. Initially I thought it would be a member of the M.-armatus-group, but the specialist for spiny eels, Ralf Britz from Natural History Museum in London led me to the idea to take a closer look on the caudal fin. Indeed this fin is fairly separated from the dorsal and the anal fin in Mastacembelus sp. „Nargis“ , while it is merged with these fins in the M.-armatus-group. Ralf thinks that M. sp. Nargis is closest to M. caudiocellatus, but of course he also says that more and detailed observations have to be done to proof this. In the meantime it is best to name the fish Mastacembelus sp. „Nargis“.

It is much likely that Mastacembelus sp. „Nargis“ belongs to the medium sized members of the genus and will attain a maximum length of about 25 cm or so. Our (short) experience with the fish shows that it is as peaceful, gregarious and secretly as one expects from a member of this relationship.

Betta ferox

17. March 2017

Sometimes we receive wild collected specimens of that very rare species of Betta. The mouthbrooding species is known so far only from a very small area in Thailand (Bori Pat). Here the fish inhabit brooks with soft and slightly acidic water. The water temperature there is around 25°C. Maximum length reported is about 8 cm, male become generally larger than the females. Females have almost no shining scales on the body.

Corydoras fowleri / coriatae

17. March 2017

The very long snouted Corydoras fowleri has been described scientifically in 1950 on the basis of a single specimen. Since that it has not been seen for decades anymore. Only at the end of the 1990ies imports from Peru arrived. The imported fish proofed to be very variable in respect of coloration. It is still a matter of debate wether C. coriatae represents only one of these sports or wether the species is a valid species on its own. But who cares? In any case they are very impressing, beautiful aquarium fish!

Phenacogrammus interruptus Albino

15. March 2017

Currently we receive beautiful cultivated albino Congo Tetras (Phenacogrammus interruptus) from Southeast Asia. Like in all true albinos the eyes of the fish are red due to the genetically caused lack of black body pigment (melanin). In many other species of fish albinos have a uniform whitish, yellowish or flesh-coloured body. Not so in the Congo Tetra. The iridescent colours of the body of that species are also extant in the albino variety. This makes the fish look so extraordinary nice.

Lexicon: Phenacogrammus: from ancient Greek, meaning “with tricky line”; this refers to the fact that the shape of the lateral line cannot be used to distinguish this genus from other genera. interruptus: Latin for “interrupted”. Refers to the shape of the lateral line.

Apistogramma borellii Paraguay wild

11. March 2017

Recently we received beautiful wild collected specimens of A. borellii from Paraguay. This species is an ideal aquarium fish. In contrast to many other species of the genus A. borellii is completely undemanding regarding water chemistry. Even in medium hard, slightly alcalic water the species thrives well and even breeds. The behaviour of A. borelli is similar to most other Apistogrammas: it is a polygamous species (that means each male breeds with several females), a cavebrooder, and the female has to do the most work in respect of taking care for the fry. However, A. borellii is among all the different types of Apistogramma the one that fits best to human ideals: it is even possible to keep it in pairs and every now and then even males take care for the brood. It is recommended to keep the fish in unheated aquaria during some weeks of the year. This will lead to a longer life in A. borellii and healthier fish.

During the current photosession we observed by chance that the neck-pattern of the fish formes so-called „eyespots“. These eyespots make the fish look by far bigger for possible predators. To the best of our knowledge this phenomenon has not been been mentioned for any Apistogramma species so far!

For our customers: the fish have code 615703 on our stocklist. Please note that we exclusively supply the wholesale trade.

Lexicon: Apistogramma: ancient Greek, means “with unreliable line”. It is not known wether the lateral line organ or the pattern is meant. borellii: dedication name.

Black winged dwarf hatchets

11. March 2017

There are two species of Black winged dwarf hatchets recognized. These charming little creatures hardly reach 3 cm in length. From Peru and Colombia we get occasionally Carnegiella schereri. The fish, however, are usually sent under the name of „Gasteropelecus sternicla, size small“. In fact both species have a very similar coloration, but C. schereri lacks, like all species of Carnegiella, the adipose fin, which is always present in species of Gasteropelecus.

From Brazil we get Carnegiella marthae. Both species of dwarf hatchet are so closely related that in former times they were considered only as subspecies to each other. In that case they were named Carnegiella marthae marthae and Carnegiella marthae schereri. Both species can easily distinguished by the coloration. C. schereri has always a spotted belly, in C. marthae the belly is striped.


For our customers: Carnegiella schereri has code 214152, C. marthae 214002 on our stocklist. Please note that we are supplying the wholesale trade only.

Danio sp. Hikari Blue & Yellow

8. March 2017

Hikari-Danios belong to a scientifically still undescribed species of Danio from Burma. The closest relative is Danio kerri. However, Hikari danios are by far more colorful than D. kerri and really beautiful fish. Keeping and breeding Hikari Danios is absolutely comparable to the very well known zebra fish, Danio rerio. Hikari danios attain a maximum length of about 5 cm.

It has been a quite long time since the last import of these pretty fish. Now we were able to get them again. By that opportunity we found that we had two different codenumbers for Hikari danios, one for „blue“ and one for „yellow“. We asked our supplier and he answered: in fact the fish have formerly been assorted in blue and yellow ones until we became aware that the blue ones are the females and the yellow ones the males…

Chaetobranchopsis australis

8. March 2017

Here it is: the cichlid with the probably most interesting mode of feeding from Paraguay! Chaetobranchopsis australis is specialized in feeding small planktic organisms. The up to 12-14 cm long fish swallows water like a vacuum cleaner and sieves the plankton with long gill rakers out of it. Obviously at the time of our importation – last september – the plankton in Paraguay is rather rare, for the fish are more skinny than we like it; but we are sure this has become corrected in the meantime in the fishhouses of our customers.

Chaetobranchopsis belongs to the very few species of cichlid in which the breeding behaviour is absolutely unknown. Aquarium fish have been observed in cleaning stones, so they might be open brooders, but no one knows!

Hemiloricaria teffeana

6. March 2017

The vicinity of Tefé (written Teffe in elder publications) in Brazil is a place of wonders in aquarists eyes. When the name Tefé is spoken everybody is reminded in beautiful Green Discus and gorgeous Apistogramma agassizii from that region. But ther also lives a very attractive whiptail catfish: Hemiloricaria teffeana. However, the species has a wider distribution, like (on a species level) Green Discus and Apistogramma agassizii also have.

Pelvicachromis pulcher wild Yellow

6. March 2017

The yellow sport of Pelvicachromis pulcher originates from southwest Nigeria. Here they are collected west of the Niger delta in the area of the Ethiop river. The names Yellow, Red or Green for the different sports of P. pulcher refers to the colour of the opercles; all of them get a red belly at times. In all Pelvicachromis the females are the more attractive fish, P. pulcher is no exception from that rule. One can study in wild collected fish the variation of the eye-spots in die dorsal fin of the females, which can differ individually from zero to five.

Hemigrammus coeruleus

3. March 2017

Among the most sought after species of tetra is Hemigrammus coeruleus. The species attains a maximum length of about 6 cm and look even pretty in the regular coloration – a bit similar to the well known glowlight tetra (Hemigrammus erythrozonus). But when the fish come in breeding condition, they look really spectacular! The males become so deeply red that one might think to see a different species! Sadly the fish is hardly available as wild collected ones. We recently obtained only 5 specimens! But we expect in the very near future a good number of German bred ones.

Hemichromis sp. Neon

3. March 2017

If the only thing a hobbyist cares for for be the coloration, we would hardly need other species than Jewel Cichlids. The „Neon“ is an artifical sport, most probably bred by crossing different species and selection. The blue iridescent spots, present in most species of Hemichromis, are much larger in the „Neon“ sport. With respect to the body shape, the „Neon“ is closest to H. guttatus.

But colour is not everything. Sadly all Jewel Cichlids have in common that it is impossible to know wether an individual will be peaceful or agggressive. Within one species both types of behaviour can appear. Some specimens are lambs, others are wolves.

However, the breathtaking splendid coloration and the really wonderful family life of these cichlids are worth the risk!

Melanocharacidium sp. Peru

3. March 2017

The ground tetras belonging to the genus Melanocharacidium can change their coloration drastically. This makes a determination often pretty difficult, because the characters used in scientific papers to distinguish the species cannot be seen in life fish and the colours exhibited in preserved specimens may be very different from those observed in life specimens.

The genus Melanocharacidium contains so far nine scientifically described species, none of them has been ever reported for Peru. The only species that lives „nearby“ is Melanocharacidium rex from Ecuador. Sadly there are only two known specimens; however, it seems to be unlikely that our fish belong to the species M. rex, for the type specimen of M. rex is larger than 10 cm, while our fish seem to be at least sexually differentiated – they are currently 4-5 cm long.

So in all probability our imports belong to a scientifically unknown new species. The fish are very entertaining in the aquarium. They are more bottom-bound than their relatives, the ground tetras of the genus Characidium, which may occassionally be found swimming in the free water column. Depending on mood, our Melanocharacidium can look almost black, in other moods they exhibit a dark horizontal band that is followed by a brightly shining one.

Trigonostigma hengeli

1. March 2017

Currently, from a scientific point of view, only four harlequins are distinguished (plus the aberrant Trigonostigma somphongsi); however, genetic studies and – as well – simple observation of live, wild collected specimens of different origins clearly show that there are many more species. Trigonostigma hengeli is the tiniest and most dainty species of the three accepted ones. It hardly grows larger than 3 cm. The species is found on the large Sunda islands of Sumatra and Borneo. The typical blackwater species has a bright shining stripe over and in front of the triangular lateral spot.

We have beautiful wild collected specimens in stock. Usually they show a light pink and orange basic colour, but if they come in mood for breeding they develop an intensive reddish and purple colour. The photographed fish are only 2 cm long (about 2.5 cm inclusive the caudal fin) and obviously fully mature. The common name „swift (harlequin) rabora“ should be used preferably for that species instead of „glowlight rasbora“ (which leads to confusion with Trigonopoma pauciperforatum) or „lambchop rasbora“ (which is also used for Trigonostigma espei).

Oryzias dancena “Thailand”

1. March 2017

Usually we obtain the rice fish (Oryzias dancena, in elder books often referred to as O. melastigma) from India. This is also the country from where it as been described scientifically. But now we obtained very healthy and vivid specimens from Thailand.

Oryzias dancena can be distinguished from other, similar species quite good by the white seamed fins. The anal fin of the male has an irregular border. In very old males the finrays may be even extended. The females of this species carry the eggs after spawning around for a while, before they deposit them in plant leaves. This behaviour is typical for all Oryzias species.

Oryzias dancena are absolutely peaceful fish that fit perfecty for any community tank. Here they live basically in the upper third of the tank. Feeding Oryzias is problem-free, for the fish take readily any types of usual fish food. However, food particles must not be too large. Hard, slightly alcalic water is preferred, but one can say that any water that can be used a drinking water for humans can be used to keep and breed Oryzias dancena. The fish attains a maximum length of about 3-4 cm.

Myxocyprinus asiaticus

27. February 2017

We have the Chinese Whimple Carp, sometimes called the Batman-Loach, almost anytime in stock. Sadly the species is in danger of extinction in the wild, mainly due to hydroelectric power stations. All specimens traded come from aquaculture and are bred in captivity.

Usually we get the fish from Singapore, but as a test we ordered some from a new supplier from Honkong now. Of course we observed these fish very carefully and found that there are two different phenotypes. Some specimens are reddish and the mighty dorsal fin is rounded at its tip. Others are rather black-and-white and the dorsal fin of these fish is much more pointed. Both phenotypes can be found in fish of the same size, the photographed ones are both 10-12 cm long. Do these differences in coloration represent the different sexes? That would be astonishing, as all whimple carps in the trade are still small juveniles. This fish can attain a maximum length of about 1.2 metres and a weight of about 23 kg; the adults look totally different, too.

Well, we will see. We will put the two photo models in a 5.000 litre tank and see how they develop.

Due to their maximum size only juveniles can be kept in normal sized home aquaria. Later the fish have to move in really big tanks or garden ponds. The species is winter-hardy in central Europe. They are much sought for to be kept along with koi carps, for Myxocyprinus is a algae eater and helps to keep the pond clean.

For our customers: the fish have code 438003 (6-8 cm) and 438005 (10-12 cm). Please note that we exclusively supply the wholesale trade.
