This is one of the gobies imported as an ornamental fish shortly after the beginning of the 2nd century (1905) already. Since then she has always found her friends, but was never very popular in the hobby. This is probably due to the quite impressive size that this goby, which is widespread along the West […]
Many cichlids from Lake Tanganyika have different local populations that also look more or lress different. The snail cichlid Lamprologus brevis (sometimes also called Neolamprologus brevis, the species belongs neither to one nor to the other genus, but to a genus still to be described) has a lake wide distribution and therefore it has become […]
According to the current state of science, the predatory tetra species Erythrinus erythrinus is widespread throughout practically all of South America: Argentina, Brazil, Ecuador, Peru, Colombia, Paraguay, Bolivia, French Guiana, Guyana, Suriname, Trinidad and Tobago and Venezuela. However, they look somewhat different everywhere, so that one must assume that in case of a modern revision […]
The L-number catfishes are like us humans. There are pretty, very pretty and extraordinarily pretty specimens. To the latter group belong the L134 (Peckoltia compta) from the Rio Tapajós, which we currently have in stock. P. compta belongs to the most recommendable L-catfishes at all and unites all desired characteristics of this group in ideal […]
In small numbers we received German bred specimens of these pretty bristle-noses. Ancistrus patronus is one of the numerous white dotted, black species and was known in the hobby as Ancistrus sp. “Puerto Ayacucho” and A. sp. “Rio Parucito” before its scientific description in February 2019; the numbers L125 and L150 were given to imported […]
Update: es handelt sich um die Art Ageneiosus lineatus Ribeiro, Rapp Py-Daniel & Walsh 2017 The dolphin catfish were only recently revised and divided into two genera: Ageneiosus and Tympanopleura. Tympanopleura are the smaller species. They are characterized by a circular structure immediately behind the edge of the gill cover, which looks like a tympanum. […]
Sometimes you don’t know what to admire more: the breeding skills of Betta freaks or their creativity in inventing new names. However, these candies are real beauties; each animal is individually patterned and spotted, so they are unique! Our dear friend Kamphol has sent us an exclusive collection of these beauties from Thailand. For our […]
The pupfish of the genus Cyprinodon live, so to speak, in the limbo for fish. Once the area, which today represents the desert regions of the western USA and northern Mexico, was a huge lake plate, the fish there lived in paradise. But the lakes gradually dried up over the millennia. Today, some species of […]
The Inle Lake in Burma has a high proportion of endemic fish species, i.e. fish that occur exclusively there. One of them is Inlecypris auropurpureus, a Danio with vertical stripes on a golden band. The number and shape of the stripes are slightly different for each individual. Inlecypris is closely related to the species placed […]
Such a pretty little fish and such an ugly confusion about the name! Corys, which look like the bronze cory, Corydoras aeneus, appear in whole South America. However, these are certainly different species, there is general agreement. Only – how to name them correctly? Whether the cory, which is currently called Corydoras venezuelanus “Orange” in […]
Currently we can offer beautiful offspring of one of the most beautiful Channa species: Channa aurantimaculata. The species originates from the north of India, where it can sometimes get quite cool. Therefore the summerly care of the up to 50 cm long animals (normally they become in the nature, however, only 20-25 cm long) in […]
Brachygobius doriae has been confused with B. xanthozonus for decades. We also received the fish under that name and stocked it so, because almost all aquarium books and websites depict B. doriae, but name it B. xanthozonus. However, B. xanthozonus has more than 50 scales in the horizontal row (our fish have somewhat more than […]
The genus Nimbochromis is probably best known to the aquarists through the “sleeper”, N. livingstonii. All species of Nimbochromis have a Camouflage pattern from irregular, brown spots. N. livingstonii uses this to mimic a decomposing fish, because fish carrion looks very similarly patchy. So the sleeper lies on his side on the ground and plays […]
After Paraguay had closed its doors for half a year for the export of ornamental fish, now imports from the southern country in South America reach us again. Among them also various Ancistrus species, which are often sent mixed. It has become common practice in the trade to call these animals Ancistrus tamboensis, which is […]
The Jaguar catfish (Liasomadoras oncinus) belongs to the rarities in the aquarium. Also in the large museum collections of the world the species is only sparsely represented, so that the knowledge about these animals is small. In the aquarium, they belong to the very sensitive species that only experienced aquarists should dare to approach. The […]
The real or Heckel discus is maintained considerably more rarely in the aquarium than brown, blue or green discus and their sports and becomes as good as not at all bred. It is therefore only regularly available as a wild collected fish. At the moment we have some very nice, well-adjusted Heckel varieties in our […]
From the many Central American cichlids, that were grouped in the gigantic collective-genus Cichlasoma earlier, most species are cared for only by the experienced “old hares” among the aquarists, who don’t want any more a colorful community aquarium but prefer a preferably big aquarium with few, characterful fishes. The Central American cichlids are perfect for […]
This beautiful loach comes from Burma, where it is found in the Irrawaddy system. They are exceptionally lively animals that are constantly in action with each other. For this reason, it is not acceptable to combine fish that love peace with Paracanthocobitis rubidipinnis. The animals – they become about 6-7 cm long – are however […]
When one sees these sleeper gobies from the Indo-West Pacific region, where they are very common, for the first time, one spontaneously thinks of an oversized Australian spotted goby (Mogurnda). The main difference between Giuris and Mogurnda is – aquaristically speaking – that the tiny larvae of Giuris develop in the sea, while the much […]
Every aquarist probably wants to visit the habitat of his fish once. We were 6 aquarists from the Berlin area as well as from the south-southwest of Germany. Through Roman Neukirchen from the company Aquarium Glaser we got the opportunity to have a look at the transport routes from the catch of the fish in […]
Currently we have two forms of very attractive Zebra-Otocinclus from Peru in stock. The first species, Otocinclus cocama, is more commonly available. It shows a rather dense pattern of vertical black stripes on a light background and has the code number 274154 (see also http://www.aquariumglaser.de/de/otocinclus-cocama_de_1342.html_de_1342.html). Only in small quantities and very rarely we get a […]
We get the rare long nosed Corydoras sp. C124 occasionally under the names C. cortesi (that is another species from Colombia) or Corydoras “Huangana” (so one calls the wild pigs of the species white-lipped peccary) from Peru. C124 has a very variably pattern, each individual can be recognized by his special pattern. But this time […]
Once again we managed to import a Macropodus form from Vietnam which cannot be clearly assigned. Unfortunately nothing can be found out about the original location. Some years ago we had been able to import similar animals, also from Vietnam, but they had a strong bronze shine on their body, which is missing in the […]
The loaches of Asia are an enormously species-rich fish group. Similar to the cory catfish in South America, a great part of the species has not yet been scientifically described. A well recognizable species is the Zodiak Loach, Mesonoemacheilus triangularis, from South India; here it occurs endemically in the Western Ghats. The genus Mesonoemacheilus differs […]
Among the driftwood catfishes are some quite attractive coloured species. This is a bit astonishing, for these catfishes are usually strictly night active and hide during daytimes in caves or crevices. However, well settled animals usually come out of their wholes at feeding times in the aquarium. Trachelyopterichthys taeniatus belongs to the really attractive species. […]
About 80 years ago, a German breeder found by chance an albinotic paradise fish among a brood of normal siblings. The breeder was successful in rearing the fish and this animal became the ancestor of all albinotic paradise fish known today. However, breeding albinotic paradise fish is not that easy and so they always were […]
One of the longest known Leporinus species is L. friderici. It was already described in 1794 under the name Salmo friderici. The author, Marcus Eliser Bloch, writes: “This fish is a resident of Surinam’s waters. I received it from the present governor, the Lord of Friderici, along with several other fish. He has an excellent […]
The magnificent Corydoras robustus belongs to the biggest species of its genus. Up to 95 mm standard length (i.e. without caudal fin) have already been measured in females of this species. Females become somewhat bigger than the males. Both sexes develop long dorsal fin rays, what looks very nice. For more pictures of adult animals […]
As early as 1914 the then very prominent German aquarist J. P. Arnold illustrated a new species of Rasbora in a German aquarium magazine, imported by the company Scholze & Pötzsche and said to originate from Sumatra. In 1922 E. Ahl from Berlin Museum described this species scientifically as Rasbora urophthalma and since these days […]
The probably prettiest freshwater pipefish is Microphis deocata from India. In its homeland it lives in clear running waters at the foot of the Himalaya. Unfortunately this pipefish is very sensitive to transport. It neither tolerates water deterioration nor can it starve for long. As a food specialist it also requires living food, this species […]
After a quite long time we were able to import the Indian Pearl Spot, Etroplus suratensis, once again. Of the three species of Indian cichlids this one is the largest. Record dimensions of up to 40 cm were reported. But normally this fish becomes only about 15 cm long, it is sexually mature from about […]
Until quite recently all species now placed in Devario have been placed in Danio and most of them were considered to be varieties of a single species, D. malabaricus. But even earlier a good number of species has been described scientifically, most of them became forgotten later. One of these species is Devario annandalei from […]
For some time now we have been able to offer offspring of this big bichir (see https://www.aquariumglaser.de/fischarchiv/polypterus_endlicherii_nachzuchten_en/). With the current delivery we noticed the bizarre outer gills, which have young animals of all Polypterus species. They give these primeval fishes a very peculiar appearance. For our customers: the animals have code 163312 on our stocklist. […]
In their Central American home countries, the predatory colorful cichlids, that are classified currently in the genus Parachromis – before this, they were placed in Cichlasoma or Nandopsis – are called “Guapotes“. That means “the big pretty ones”. And actually, these species, some of which can reach up to 50 cm in length, are very […]
The platinum hatchetfish, Thoracocharax stellatus, is regarded as biggest species of the hatchetfish. In the scientific literature, up to 6.8 cm of standard length (without tail fin) are indicated for the species. However, much smaller animals are always imported. The specimens that we currently offer as “large” have a standard length of about 3.5-4 cm. […]
The first tropical freshwater puffer fish, which was imported in 1903 for aquaristics and soon bred, was the common or emerald puffer fish, at that time still known as Tetraodon cutcutia. The species remains quite small with a maximum length of 9 cm, is attractively colored and easy to keep, but unpredictably biting against conspecifics […]
In spite of their largely nocturnal nature, the driftwood catfishes have meanwhile gathered a small fan community behind them, which enthusiastically cultivate and breed them. Surely it contributes to the fact that these catfishes have an internal fertilization, whereby the females can produce a fertilized clutch sometime without direct intervention of a male, since the […]
Sadly this beautiful dwarf cichlid is only occasionally available, but currently we were able to import once more beautiful, fully grown specimens. The fish display all the behaviour that makes the keeping of these fish so desirable. Like its close relative A. uaupesi, which differs from A. iniridae mainly due to the lyra-shaped caudal fin […]
Nobody would keep this fascinating frogfish from South East Asia due to its coloration. The bizarre shape and the expressive eyes nevertheless make it a desirable species for the aquarium. This frogfish lives in the wild in river mouths; although it is possible to keep the fish in pure freshwater, it is better to add […]
One of the most common tetras from the Amazon and Orinoco is Hemigrammus bellottii. The species is easily recognizable by the golden longitudinal stripe and the red eye; other pattern elements (tail spot, fin coloration etc.) are usually missing. Only a shoulder spot can be present from time to time – depending on the mood. […]
These intensively colored crayfish originate from Papua New Guinea, where they are found on the Vogelkop Peninsula. „Irianto Red” is a colour variant of the Cherax snowden, which was only scientifically described in 2015, while Cherax holthuisi already received its scientific name in 2006; before that, C. holthuisi was known as “apricot crayfish“, while C. […]
The tetras belonging to the genus Pyrrhulina combine the advantages of two basic groups of ornamental fish. The first group are the schooling species that are always visible and swim merely in the open water: tetras and barbs. The second group has a fascinating behaviour and takes care for the brood: the cichlids and the […]
Among the driftwood catfishes are some quite attractive coloured species. This is a bit astonishing, for these catfishes are usually strictly night active and hide during daytimes in caves or crevices. However, well settled animals usually come out of their wholes at feeding times in the aquarium. Trachelyopterichthys taeniatus belongs to the really attractive species. […]
Currently we received an import from Venezuela, which included small, only 3-4 cm long specimens of Leporacanthicus triactis, also known as L91. Among them are an unusually large number (approx. 10) of unusually beautifully drawn variants. Normally small L91 do not look much different than the adults, only a little lighter in basic tone. But […]
The big emerald-corys of the genus Brochis clearly differ from all species of Corydoras through the long back-fin, that contains essentially more fin-rays. While Corydoras have 7-8 rays in the back-fin, Brochis have 10-18. The care of all Brochis is easy and hardly differs from that of the remaining corys, however, the breeding succeeds only […]
The black banded barb or spanner barb is an old friend in the aquarium, although it is somewhat out of fashion. In former times it was called Barbus or Puntius lateristriga, at present it is assigned to the genus Barbodes. The pretty, peaceful animals are widespread in Southeast Asia, where they mainly inhabit clear waters, […]
Once more we are able to offer a beautiful dwarf livebearer that proofed to be a bit problematical in respect of breeding – not keeping! – in a long time sight under traditional aquarium conditions. However, under the open skies of Southeast Asia they breed pretty well. Flexipenis vittatus is also often placed in Gambusia. […]
Danio feegradei was first described by the famous Indian ichthyologist S. L. Hora in 1937 by a single specimen originating from the Thandwe river in Myanmar (former Burma). Since then no reports have been published about new findings in the same river nor in other areas. Only in 2007 this beautiful barb fish has been […]
We have already mentioned it: currently we have three species of the genus Hoplias from Venezuela in our stock. The common wolf tetra (Hoplias malabaricus) has a huge distribution area, but it is very likely that this “species” proves to be a species complex consisting of several, at least partially undescribed species. With the “Hoplias […]
The cichlids of the genus Tropheus are widespread around the gigantic Lake Tanganyika in numerous locality-variants. The sometimes very different looking animals testify to rising and sinking water levels over the millennia. As strict Aufwuchs eaters, Tropheus cichlids are not able to migrate over larger sandy areas and so the stone reefs of the lake […]
Right now we have three Hoplias species from Venezuela in our stock. Hoplias curupira belongs to the real rarities and is accordingly sought after among predatory fish fans. With a final length of about 40 cm the stocky species remains relatively small. It belongs within the genus Hoplias to the so-called H.-lacerdae group, which besides […]
The Pearl Gourami (Trichogaster leerii) is an absolute classic among the ornamental fish. The species is always available in the petshops all over the world and they are usually quite cheap. These traded fish are bred ones. Wild collected ones are hardly ever offered; the species is endangered in the wild, because the habitats become […]
After many years we were finally able to import some full-grown (8-10 cm long) specimens of this as rare as beautiful and interesting sucking barb species. Garra sp. Red Tail is still scientifically undescribed, although the collecting site (the Kasat river in the west of Thailand) is well documented. For the history of discovery of […]
In two large specimens (they are currently 20-25 cm long) we have received the extremely rarely imported Centrodoras brachiatus from Peru. The up to 40 cm long catfish are widely distributed in the Amazon system and also occur in Brazil and Colombia. Typical is the form of the lateral bone row, whose shields are very […]
Only extremely rarely, this pretty, maximum 7 cm long killifish is offered in the trade. Formerly, Fundulopanchax spoorenbergi was placed in the genus Aphyosemion. The species appears from Nigeria to Cameroon. No fear of short-lived Killifishes: this species is approximately as long-lived as other popular aquarium-fish, like Guppys or Platys. It should be noted that […]
We obtained a somewhat irritating import of a very rare species of tetra last week from Peru. In all probability, it is Moenkhausia simulata; however, our new import differs slightly from the previously known M. simulata in coloration. All other tetra species with a pattern of several horizontal stripes (Astyanax lineatus, A. kullanderi, A. superbus, […]
Actually, nobody knows exactly what Colisa fasciata is; because the specimen on which the first description is based was lost in the turmoil of the French Revolution and where it is supposed to come from (Tranquebar in the south of India) there are no gourami at all. That’s why everything that isn’t Colisa lalia, C. […]
Algae are probably the most widespread of all the hazards that can hit an aquarium. However, algae are not a bad thing in themselves, they just do not correspond to our aesthetic ideas. In nature, algae growing on stones, plants and pieces of wood and the microorganisms living in them – together they are called […]
Two species of so-called Lyratail-Apistogramma come from Peru, which are very similar to each other: A. martini and A. pantalone. Both are among the most delicate and difficult Apistogramma species ever, but this is not a law of nature, but depends on circumstances in nature that have not yet been understood. At the beginning of […]
Three species of tetra in northern South America are obviously close relatives to each other and often confused: Hyphessobrycon loretoensis from Peru, H. metae from Colombia, and H. peruvianus, again from Peru. From these, H. loretoensis has been portayed here: http://www.aquariumglaser.de/en/hyphessobrycon-loretoensis_de_1188.html. Currently we were able to import the second Peruvian species once more, H. peruvianus, […]
Once again Kamphol has provided us with very special breeding fighting fish, which currently enjoy particular popularity among the breeders of these fish jewels in Thailand. The “Spade Tail” is one of them. Basically there are different possibilities in animal breeding to get to new forms. One way is to inbreed as closely as possible, […]
These new Betta types were certainly also bred by crossing in wild species, in this case Betta stiktos seems to have been involved; “Alien Green” looks de facto like a B. stiktos. They are all very slender Bettas, they have much more of the heritage of the Betta smaragdina alike forms to which B. stiktos […]
It is hard to understand why such a well-defined and unique species has not yet been scientifically described, although the animals have been kept and bred in the aquarium for decades. And yet it is; “Acei” is a pure popular name and not a scientific name. The species can be found in several different coloured […]
From the mountainous part in the north of Thailand, the legendary Golden Triangle between Thailand, Burma and Laos, we received two pairs of Channa melasoma. Originally this species, which inhabits clear forest streams, was described from Borneo. With approx. 30-40 cm of final-length (our animals are, including tail fin, approximately 20-25 cm long), C. melasoma […]
There are two different ways of breeding new Endler or Dwarf Guppies. One is to cross different color varieties of the pure species Poecilia wingei (Endlerguppy) with each other or to select and intensify certain color characteristics, which occur within a population, by selective breeding. The other way is to cross Endlerguppy and “normal” Guppy […]
This sand cichlid originates from Lake Tanganyika, where it is found almost all over the lake with the exception of the extreme south. Our animals are descendands from fish that were collected at Kigoma Bay; fully coloured males (unfortunately our quite young, 4-6 cm long animals do not show this yet) of this local variant […]
The panda cory from the Rio Ucayali in Peru belongs to the most popular species of the genus. This applies both to the aquarists, who have a community aquarium, and to the breeding aquarists, because Corydoras panda is quite easy to breed and productive – if you know how to do it, of course. We […]
The neon rice fish was the absolute sensation during its aquaristic discovery in 2010. At that time two neon rice fish were known: the “real” O. woworae from the small island of Muna and an O. cf. woworae from the main island Sulawesi. The most important optical difference between the two was seen in the […]
Everybody should be fooled by this unusual barb from Southeast Asia on some occasion! The wonderful 18-22 cm long specimens from Indonesia were sent to us under the name Rhaphiodon vulpinus, a predatory tetra from South America. Apart from the great shyness, the animals were in perfect condition, which is why we didn’t want to […]
In the past years we received this rare headstander, scientifically described only in 2005, which is known from the Orinoco in Venezuela and the Tapajós in Brazil, only very occasionally as a by-catch from Venezuela. Mostly the animals were found among Anostomus ternetzi or Pseudanos trimaculatus. Now we could finally import some specimens of this […]
The five banded barb is one of the most beautiful small barbs. Originally it comes from the river Baram on Borneo, which flows through the Malaysian part (Sarawak) of the big island. Once the black water species was regarded as delicate, its breeding as a high school, but these problems have long since been solved. […]
Unfortunately many Haplochromis-like cichlids of Lake Victoria are threatened by extinction due to profound environmental changes. The giant perch (Lates niloticus) introduced there, the turbidity of the water due to eutrophication and the resulting mass growth of the water hyacinth (Eichhornia crassipes) are the best known causes. For this reason, a conservation breeding programme is […]
If this catfish came from South America, then one would count it without question to the banjo catfish. But in reality, Acrochordonichthys rugosus comes from Southeast Asia, where it is widespread and science has known about it for a long time, but from where it is only rarely exported as an aquarium fish. A special […]
We received a very special fish from Peru: Anchoviella alleni, one of the very few representatives of the sardine family (Engraulididae) that lives exclusively in freshwater. The species attains a maximum length of about 10 cm. Our specimens have about half of that size. The supposed males are more slender, slightly larger and the swim […]
The habitats of Corydoras gracilis in the entry of the Rio Madeira are clearly off the beaten track of ornamental fish collectors; furthermore, the nimble little animals, which know how to hide themselves perfectly in the maze of branches that have fallen into the water, are difficult to catch one by one. That is why […]
From Colombia we received an import of the striped wolf tetra, Hoplerythrinus unitaeniatus. The systematics of these almost over the entire South America spread fish is poorly understood. Only the one species, H. unitaeniatus, is recognized commonly, but there are a lot of synonyms, among them the (without justification) occasionally recognized species H. cinereus (Trinidad […]
Once again we have received a beautiful fighting fish breeding form, this time even in pairs: the animals are called “Black Samurai” in a melodious way. They are very lively fish, true temperament bolts, which actually deserve the name “fighting fish”. Excited males make little difference between males and females, both are heavily turned on. […]
The Spotted Gourami, Trichogaster trichopterus, is one of most widespread species of fish in Southeast Asia. Its range starts in the west at the burmese/thai border, it contents the Sunda islands and reaches in the East to China. Additionally the species has been introduced almost worldwide as a food fish in tropical climates. Crossing of […]
The moderlieschen (Leucaspius delineatus) is the most recommended fish species for smaller garden ponds. Due to its miniature size of usually 4-5, rarely 8-12 cm it fits even for the smallest ponds, which must have, however, a minimum depth of 80 cm in central Europe to enable a survival during winter. The funky name […]
We received once more this new, impressive species of Garra from India. The most striking feature of the species is that they have large, shining scales on the flanks. The position and number of these scales differs individually. Depending on the light these scales shine bright blue, orange-red or golden. The fully grown males (the […]
We have received from a German breeder wonderful, fully grown Apistogramma borellii in two selections, “Opal” with red pattern on the head and “Reitzigi” with bright yellow head. With both forms, the males have dorsal fins of almost body height – fantastic animals! All photos of this post show animals of the “Opal”-form. For general […]
It took until the year 2006 that the tetra specialists Axel Zarske and Jaques Géry found out that the species described as Copella nattereri was practically not present in the hobby and that the red spotted Copella, which was named C. nattereri until then, was not known to science yet! So Zarske and Géry described […]
From Colombia comes the pretty long-snouted Corydoras simulatus. There it lives in the same rivers – the Rio Meta and its tributaries – as the round-snouted Corydoras metae. Because the latter have been known for a long time already, the scientific describers of C. simulatus chose the species name “simulatus”, in the sense of “only […]
This unique dwarf barb (max. 4 cm total length) from Burma has a red “moustache”. In males it is more pronounced than in females, but in P. erythromycter the ladies also have a moustache. Until its scientific description in 2008, the species was called Barbus cf. puntio. This species is best cared for at room […]
This is the chorus of a Rodgau Monotones´ song about a small employee who breaks out of his hated everyday life and puts on an eye patch to continue living as a pirate in the future. We had to think of this song when a magnificent Leiarius pictus from Peru arrived on Wednesday. The animal […]
Yes, this pretty magnificent killifish actually writes itself “palmqvisti” and not, as one would think, “palmquisti”; this spelling with “v” was used in the first scientific description in 1907 and may not be changed. Palmqvists Nothobranch is an old acquaintance in the hobby and was first imported in 1958 and soon also bred with good […]
Recently we received red chameleon whiptails (Pseudohemiodon apithanos) from Colombia. The coloration of the eight specimens (a ninth was a “normal” apithanos, which we also received) is really fantastic. Red variants can be found in different loricariid catfish, think of Hemiloricaria and Ancistrus, but for the genus Pseudohemiodon they are not known yet. The individual […]
We were able to import this charming zebra hillstream loach from Indonesia. The determination of the numerous species of Gastromyzon from Borneo (more than 30 different species are known from the island) is quite tricky, many species look quite similar to each other. So we cannot exclude the possibility that our fish will proof to […]
The tiger loaches (Syncrossus) are a genus of comparatively large (about 15 cm), beautiful loaches. Formerly they have been added to the genus Botia. Currently five species are distinguished, among them Syncrossus berdmorei. Sadly this species is offered only occasionally, because it belongs to the most colorful species of the genus. The natural distribution of […]
The green pufferfish (genus Dichotomyctere) are the best known aquarium pufferfish. They are brackish water animals, which, in case they should be cared for in fresh water, paying special attention to their pH value. A pH below 8 does not get them in the long run and the water should be as hard as possible. […]
Currently is season for one of the most beautiful members of the genus Peckoltia, namely L135. The species originates from the Rio Negro and can be easily recognized by the “wormline-pattern” on the head. Only two other species of Peckoltia show a similar pattern: P. braueri from the Takutu river and P. sp. L121 from […]
Why is an endangered, mouth-breeding fighting fish called like the mathematical circle number? Not so long ago, in 1986, the first of the these big fighting fishes was discovered in Malaysia by travelling labyrinth fish enthusiasts and described as Betta waseri in honour of Alfred Waser, a primordial rock of the labyrinth fish scene. These […]
Once colourful large cichlids were so popular that imports from Ecuador were organised mainly because of them. On the pacific side of the country live the “Green Terror”, so the then still Aequidens rivulatus named gold seam cichlids were called, and the “Red Terror”, then Cichlasoma festae, today Mesoheros festae. Both species become easily over […]
The blue-red Boesemans rainbow fish has not disappeared from the aquariums since its aquaristic discovery in 1981. For a time, it was so sought after that it was caught on a massive scale for export; these animals went almost exclusively to Japan, where were paid insane sums for them. There were even fears of overfishing […]
Nobody knows exactly what Apistogramma taeniata is, because the species was described in 1862 after a specimen, which is today in a very bad condition and the verbal description is more than scarce. At the time of the description, the genus Apistogramma did not yet exist, no one had any idea of its variety of […]
This crayfish was regarded as a particularly pretty variant of the zebra-lobster (Cherax peknyi) until recently and was called “Blue Kong” in the trade melodiously. Chris Lukhaup, Rury Eprilurahman and Thomas von Rintelen described it scientifically as Cherax alyciae in June 2018. We have just received these very attractive animals as wild catches from Indonesia. […]
There is no agreement on the systematic position of the livebearers living on the Caribbean islands. According to anatomical characteristics, the genus Limia is today mostly regarded as synonymous with Poecilia, but they have so many independent characteristics that Limia is almost always mentioned as a subgenus. Aquaristically this is not so important whether Limia […]
We admit it: when we unpacked the animals, we were just disappointed. Colourless tetras, obviously young, with a black longitudinal line. Quite great. Because of the round head form they reminded of the genus Bryconamericus, a very species-rich and difficult to overview genus, and because we had to book them somehow into the system, from […]
With almost 150 accepted species, the genus Hypostomus (in the broadest sense) is the most species-rich group of loricariid catfish. Unfortunately, there is no current revision of all species and so the determination of Hypostomus is usually a laborious affair, in the end often only a questionable result. Hypostomus rhantos is pleasingly easy to recognize. […]
The systematics of the widespread, small halfbeaks from South and Southeast Asia are complicated. A first revision of the genus by Mohr in 1936 summarized many previously described species under the synonymy of D. pusilla. This was followed by Brembach in 1991; the name D. pusilla was then used in the broadest sense. It was […]
