The Indian Dwarf Mudskipper, Periophthalmus novemradiatus, is the ideal aquarium mudskipper with its usually 6 cm length (in literature up to 10 cm are given, but we have never seen such large specimens, probably this statement is based on confusion with other species). In addition to its small size, it has many other favorable attributes: […]
A very long name for a very small fish! The genus Curculionichthys was established only in 2015 to accommodate dwarf sucker catfishes of the subfamily Hypoptopomatinae (formerly: Otothyrinae) of Loricariidae, which were previously placed in the genus Hisonotus. Both anatomical and molecular data showed that two independent evolutionary lineages existed within Hisonotus, namely that around […]
Among the species threatened by the construction of the Bela Monte Dam is L82, a species of loricariid up to about 15 cm long, which cannot yet be assigned to any genus described scientifically to date; it is most similar to Scobinancistrus. Also on species level L82 is not yet worked on. The only certainty […]
The marbled headstander is perhaps the most unusual of all headstanders. This beautiful fish grows to about 15-20 cm in length and is hard to mistake because of its high body shape. There is only a second Abramites species, A. eques, but it has never been imported alive. It lives exclusively in the Rio Magdalena […]
This very flat Pseudacanthicus from the Rio Tocantins belongs to the rarest L-catfishes on the market. Even before the export ban by the Brazilian authority IBAMA, which was lifted only recently, the fish came to us only very sporadically. L79 certainly grows over 20 cm long, but exactly how big is unknown. Our animals are […]
Poecilia wingei is widely distributed in the hobby after its best known local variant as Endler´s Guppy. It remains much smaller than the normal Guppy and is very popular with many aquarists because of its graceful body shape. Just as with the common Guppy, numerous local forms can be observed with P. wingei. The ancestor […]
Many rock dwelling cichlids (mbunas) of Lake Malawi live isolated on certain rocky shores. These are often miles away from other rocky biotopes, so geographic isolation leads relatively quickly to local color variations. Other cichlids of the lake, such as Sciaenchromis fryeri, are not bound to specific biotopes and occur accordingly throughout the lake. Although […]
Males of all dolphin catfishes (Ageneiosus) develop huge dorsal fin spines and a penis-like mating organ at spawning time, also strange tooth-like looking papillae on the posterior margin of the upper jaw. They use the dorsal fin spine to clamp females for mating, and fertilization occurs internally. After spawning, the dorsal fin spine is shed […]
Wertheimeria maculata belongs to the strangest thorny catfishes. You don’t see this on the relatively inconspicuous juveniles with their 6-8 cm length, but it is nevertheless so. The first thing that catches your attention is the really high price that is demanded for them. This is due to the fact that these fish are local […]
A few weeks ago we introduced you to a new pacu, which we received as Tometes kranponhah. At that time we thought the animals originated from the Rio Xingu. (see https://www.aquariumglaser.de/en/fish-archives/tometes-kranponhah-2/) In the meantime, further correspondence with our supplier revealed that the animals did indeed come from the Rio Tocantins. We have received another shipment […]
The “pointed tail” mutation, in which the middle caudal fin rays are elongated, appeared relatively late: the first specimens appeared on the market in the 1980s. It originated in the Southeast Asian large-scale breederies. The characteristic, which first appeared in the Platy (Xiphophorus maculatus), can also be transferred to other Xiphos, but the pointed tail […]
Acanthicus hystrix is one of the great myths in the literal sense. With a length of almost one meter it is one of the largest loricariid catfishes at all. In addition, the species, which was already described in 1829, is extremely prickly: “hystrix” means “porcupine”! Unfortunately, the specimen on which the description of this species […]
Everything there is to say about these wonderfully colorful cichlids has already been said about another breeding variety, the Aulonocara Dragon Blood: https://www.aquariumglaser.de/en/fish-archives/aulonocara-dragon-blood-2/ The Orange Blotched are now one of the most common Malawi cichlids on the market. No wonder: there is hardly a fish species, which shows such a variety of bright colors, like […]
The convict cichlid Amatitlania (formerly Cichlasoma) nigrofasciata is really not a novelty anymore: it has been kept and bred in aquariums since 1939. The first aquarium animals of this very widely distributed fish in Central America came from the lakes Atitlan and Amatitlan in Guatemala. The genus to which the convict cichlid currently belongs was […]
Some time ago we introduced a short-finned fighting fish breeding form (“Pla Kat”) of Betta splendens as “Hellboy”. (https://www.aquariumglaser.de/en/fish-archives/betta-splendens-pla-kat-hellboy-and-giant-halfmoon/). Now we have received Pla Kat under this name from Thailand again, but they differ from the first Hellboys in color and fins. The new Hellboys have a halfmoon tail fin, which means that when the […]
Guppy breeders are currently very active again and bring new, attractive strains on the market. The Guppy Kohaku Koi Tuxedo combines two special characteristics: The Kohaku factor, which causes males and females to have a red head combined with a red caudal fin and red dorsum; and the Elephant Ear factor, which causes the greatly […]
Paracheirodon simulans is the smallest and tiniest species of neon tetra. The maximum length is around 2.5 cm. One should not confuse this species with the neon costello, Hemigrammus hyanuary, which is also called the “green neon” occasionally. This is the reason why some people call Paracheirodon simulans the “blue neon”, but in the international […]
Our current Congo import contained among others the magnificent tetra Alestopetersius leopoldianus, which originates from Lac Mai Ndombe (formerly: Lake Leopold) and the middle Congo. With this maximum 9 cm long species one can get philosophical about the supposed objectivity of photography. Depending on the incidence of light the animal looks completely different! With the […]
The beautiful Corydoras elegans is widely distributed in the Amazon region and locally forms numerous color forms. Possibly all these variants are even independent species, but scientifically this has not been investigated yet. A color variant from the Rio Nanay in Peru stands out above all by yellow-orange tinted fins. Some males (they have higher […]
Since a long time we received again a Congo import. Beside many other interesting fishes and novelties also the good old acquaintance Nanochromis parilus was among them. These beautiful, assertive dwarf cichlids are very common in the region around the capital Kinshasa. It is astonishing that they were described by science only in 1976. In […]
Again we can announce a first import: Moenkhausia nigromarginata. For the first time ever we received some of these tetras described in 1994. The species reaches a length of about 5 cm. Striking are the blue eye, the blue back in incident light and the – sometimes more and sometimes less visible – zigzag bands […]
In the 1990s, when the large river cichlids of Brazil experienced a certain boom, also four Crenicichla species came to Europe for the first time, which were named Crenicichla sp. Xingu I – IV due to the lack of availability of a scientific name. All four grow quite large by ornamental fish standards, you have […]
Under the name “Hasemania hansseni” a new tetra has recently appeared on the market, which with its intense orange coloration is indeed somewhat reminiscent of the well-known copper tetra, Hasemania nana. However, one of the characteristics of the genus Hasemania is that it lacks the adipose fin that is so typical for tetras. This is […]
New legislation in Brazil now allows the import of species whose export was previously not allowed. One of these species is Moenkhausia rubra, which was only scientifically described in 2014. The species is so far known only from the Rio Juína and the Rio Juruena, both belonging to the upper Rio Tapajós drainage, Mato Grosso […]
Only very rarely we receive wild collected Corydoras paleatus. Imports of this species, which is widespread in southern South America, didn´t appear for more than 10 years, because many export stations in southern Brazil had to close down when some of the most important ornamental fishes of the region were forgotten on the Brazilian positive […]
There are many criteria, why to choose this or that fish for the aquarium. Those who like colorful fish should avoid Anabas. But who likes to observe biological peculiarities is well advised with the climbing perch. General information about Anabas can be found here: https://www.aquariumglaser.de/fischarchiv/anabas_de/. We have now once again imported climbing perch from Bengal. […]
The Pitbull Pleco (Parotocinclus jumbo, formerly Hypostominae gen. sp.) was one of the most popular small sucking catfishes until about 10 years ago. Then it was accidentally forgotten on the list of Brazilian ornamental fishes allowed for export. Since then, it has only been around in breeder circles. This species, very common in the wild, […]
Aquaristics is unimaginable without the multitude of colorful livebearer breeding forms. However, this also means that there is competition between the different breeding lines for the buyers’ favor. A good name clearly sells. And even if, strictly speaking, the Neon Green Lyretail is neither neon green in color nor has a lyre tail – who […]
From Brazil we received this really nice novelty, which looks a bit like an enlarged edition of the Ember tetra, Hyphessobrycon amandae. However has the “Muzel Red Cherry” two (although indistinct) shoulder spots, which never occurs in H. amandae. In addition, the dorsal fin in “Muzel Red Cherry” is red with a light margin, while […]
The Diamond Rainbowfish – Melanotaenia praecox – is one of the smallest species of the actual rainbowfishes and grows only 6-7 cm long. It shows already from 3 cm length its splendid iridescent body coloration. That is why it is one of the most popular species in the trade. With age the males become high-backed […]
Aulonocara are a specious and colorful genus of Malawi cichlids; because of their brightly colored dress they are called “peacocks” in English. They are small-animal eaters that selectively ingest small chunks of food. Another group of cichlids in Lake Malawi feeds on the algae and the microorganisms (= Aufwuchs) they contain, which grow on rocks. […]
We have already introduced several wild strains of Xiphophorus variatus, which rightly bears its scientific species name (variatus = variable). Now we have again two new variants on offer, both are German bred ones, descended from wild populations. The first is a pretty speckled fish discovered and brought back on a scientific collecting trip in […]
The bluegray mbuna or the electric blue johanni (Melanochromis johannii) was imported so early (1972) from Lake Malawi for the hobby that one still made the effort to invent a popular name for it. This was later abandoned in view of the great number of species. In the wild, these fish, like many other Aufwuchs-feeding […]
The Serpa Tetra, also called the Callistus Tetra (Hyphessobrycon eques, formerly known as H. callistus or H. serpae), is the little man’s piranha. Just like piranhas, serpa tetras have an irresistible urge to bite the fins of other fish. And they constantly want to test out who is the stronger. This makes many exciting observations […]
This interesting, about 20-25 cm long sucking catfish from Peru should only be kept by really experienced aquarists. Beside some adult specimens we could import this time also 4-7 cm long juveniles. The size of these fish is difficult to state, because one should not count the tail fin filaments, which are much longer than […]
The red-breasted shoaling piranha (Pygocentrus nattereri) is present throughout the Amazon River basin. It is the most common piranha species kept in aquariums. The breeding of these animals succeeds according to plan. Pairs are formed from a shoal, which spawn in bottom pits; the parents guard the spawning site, there is no brood care beyond […]
The Rio Candelaria is a lowland river in Central America. It originates in northern Guatemala and flows through regions there and in southeastern Mexico whose jungle landscapes were almost untouched by man for a long time. The Rio Candelaria gained sad fame because the conquistador Hernán Cortez had the last Aztec ruler Cuautémoc, a fierce […]
For the first time we can offer this pretty Leporinus, which was scientifically described only in 2000. Be careful not to confuse it with L. octomaculatus, because this is a completely different species; here the confusion of one letter has consequences! So far Leporinus ortomaculatus is known from the Rio Surumu, Roraima, Brazil and from […]
One of the most beautiful freshwater fishes of all is Channa micropeltes. This snakehead lives in groups and its favorite pastime is eating. It is therefore constantly on the lookout for food and swims lively in a shoal through the aquarium. Although every word up to this point is true, it is still only half […]
The correct name of this beautiful catfish from the Rio Xingu is a matter of dispute among experts. In many parts of South America similar looking catfishes can be found, which are all close to the species already described in 1840 as Hypostomus emarginatus. These were assigned to the genus Squaliforma in 2001, and to […]
Quite clearly – none at all! Because this genus is exclusively from South America. But in Indonesia these beautiful large tetras are bred and occasionally we import juveniles from there. Then one wonders which species it is. We get them as S. insignis and so we sell them on, but is the determination correct? This […]
The zebra cichlids of Lake Malawi were among the first cichlids to come to us from this great lake in the 1960s. At that time they caused real enthusiasm storms. Aquarists had no idea of the enormous diversity of species and forms that exist there. So the zebras were simply called “Pseudotropheus zebra” after one […]
The first documented domesticated form of the Siamese fighting fish (Betta splendens) was a Spadetail. That was in 1849. At that time certainly fighting fishes were bred for a long time, but they resembled more or less the wild fishes and were selected only for their fighting characteristics. The appearance of these animals was a […]
Fully grown angelfish of the various breeding forms are comparatively rare in the trade. The reasons are obvious: The breeding is time and space consuming, because they are still cichlids, which demand a certain individual space for themselves. That’s why XL angels have to be comparatively expensive. But occasionally such animals are in demand and […]
Finally we have the dwarfish Neoheterandria elegans in our stock again. They originate from German breeding. These are among the smallest livebearing toothcarps regularly kept in the aquarium. Males grow to about 1-2 cm long, females up to 3 cm, but usually around 2 cm. The Teddy Livebearer, as it is called to distinguish it […]
One of the oldest aquarium fishes is the Buenos Aires tetra, of which the correct scientific name was only recently determined: Psalidodon anisitsi. To most aquarists, however, the species is probably still known as Hemigrammus caudovittatus (or Hyphessobrycon anisitsi), and it is under this name that it is found in most aquarium books. Since its […]
Nannostomus, also known as pencil fish, propel through the aquarium like small, colorful zeppelins. The unusual, somewhat stiff-looking swimming style makes them unique in the colorful world of tetras. There are quite a few species of Nannostomus-species, but the Red Pencilfish (Nannostomus beckfordi), which grows up to 6.5 cm long (but appears smaller due to […]
The species of the genus Lepidiolamprologus belong with about 15 cm final length to the largest representatives of the Lamprologus relationship in Lake Tanganyika. They are predatory animals that like to feed on small fish. Like so many predators, they are remarkably peaceful toward fish that do not serve as food. In the lake, Lepidiolamprologus […]
Archerfishes can be divided into two groups: those that live in the brackish water of estuaries, reproduce there as well (all archerfishes are free spawners without brood care) and can also live in pure seawater. These species are therefore widely distributed along the coasts of the Indo-Pacific from India to Japan and Australia. And then […]
If there is one fashionable fish that has defined the last decade, it is the Endler guppy, Poecilia wingei. This small guppy species has countless fans all over the world and efforts are made to preserve the “pure” strains of wild caught variants. However, in the wild these wild variants are by no means uniformly […]
In 1915 the scientist Carl Eigenmann described a new tetra genus, which he named Megalamphodus. Type species is M. megalopterus, an aquaristic very well known species: the Black Phantom Tetra. In 1997 Megalamphodus became a synonym of Hyphessobrycon. Of the remaining species assigned to Megalamphodus in 1915 (ecuadoriensis, eques, heteresthes, melanotus, micropterus), only the Serpae […]
We are proud to present this unusual first import. The rarity of this pretty large catfish in the hobby stands in strong contrast to the fact that it was scientifically described as early as 1876, is widespread (our animal comes from the Rio Negro in Brazil, but it also exists in the Rio Madeira, in […]
In the meantime it has turned out that these animals are Mylesinus paucisquamatus from the Rio Tocantins and the statement that they came from the Rio Xingu was a mistake. New species of large fish are still being found in the rivers of South America, despite they have been well studied. This is mainly due […]
The “Cape Lopez” (Aphyosemion australe) is one of the longest serving killifishes. It was discovered due to aquarium imports from Gabon (Ogooué River estuary, Port-Gentil, Cape Lopez, northwestern Gabon), from where it was first brought in 1913. In 1921 Arthur Rachow described it as a new species, then cautiously as Haplochilus calliurus var. australis. The […]
We have received juveniles of the “Black Lancer” from Indonesia. The adult fish is pitch black with a white caudal fin and a narrow white horizontal stripe running along the middle of the body. The stripe begins below the dorsal fin and extends into the caudal peduncle. The 4-6 cm juveniles of this up to […]
We could import the beautiful species Pyrrhulina brevis already several times from Peru (see https://www.aquariumglaser.de/en/fish-archives/pyrrhulina-brevis-2/). This time they have a very intensive pattern in the anal fin, which reminds of an eye spot and corresponds with a similar pattern in the caudal fin. They are magnificent fish! For our customers: the animals have code 286754 […]
This is probably the most beautiful species of the bumble bee gobies, because the males (also some females) develop a splendid orange-red in the rear half of the body. The females are mostly yellow in color, but they are easily recognized by the comparatively smaller head regardless of coloration. The species was and still is […]
From the upper Amazon in Peru comes the beautiful garnet tetra, which grows 3-4 cm long. The very peaceful animal actually has characteristics like a carbuncle, a gemstone, which in fairy tales has the ability to make the owner invisible: because the eye and tail root of Hemigrammus pulcher shimmer like gemstones, but the individual […]
The tetras of the genus Leporinus (the genus name is a derivative of the Latin word “lepus” for “hare”) belong to the characteristic river fishes of South America. They owe their name to the shape of their mouth in combination with the elongated “hare teeth” in the lower jaw of some species, which reminded the […]
The needle catfishes (Farlowella) are one of the most species-rich genera within the whiptail catfish relationship with currently 30 recognized species. The species look very similar to each other. Distinguishing features are mainly the arrangement of the bony shields along the flanks and on the abdomen, which is naturally hard to recognize on the living […]
If you like Danios you will love Opsarius! They are lively, very elegant swimmers, more similar in behavior and appearance to trout than to other danios. As a popular collective name for the group, which includes the genera Opsarius, Barilius, Raiamas and Opsariichthys with a total of about 70 species in Asia and Africa, “Trout […]
Hearing the name Tabasco, the first thing that comes to mind for a Central European is the spicy chili sauce. However, the Platy (Xiphophorus maculatus) that bears this name is neither particularly fiery nor particularly red – it merely originates, like the chili sauce, from the Mexican state of Tabasco, where this population was first […]
The genus Lithodoras belongs to the thorny catfishes (Doradidae). There is only one species scientifically described, which has its distribution in South America: L. dorsalis, which inhabits the Amazon basin; in addition, the species was reported from a creek near Cayenne (French Guiana), but the latter occurrence still needs confirmation. The maximum length of L. […]
From Indonesia we have received captive bred specimens of a gar species, which stands out due to its reddish brown (normally blackish, gray or silver) basic coloration with partly brick-red coloration parts. Unfortunately, it is not possible for us to name the species correctly, because the reliable identification of gar is only possible on the […]
Currently we have very nice Boraras merah in stock. The species is a very close relative to B. brigittae and at least in some populations the females of B. merah look like B. brigittae and only the males have a typical B. merah pattern (see also http://www.aquariumglaser.de/en/boraras-brigittae–boraras-merah_de_1107.html). Cross-breeding experiments also show that both varieties are […]
Moonies are magnificent brackish water fish. In pure fresh water they should be kept only temporarily, if possible, because they are very sensitive there. If it has to be freshwater, then the pH value must not drop below 7 and the nitrate value must not rise above 50 mg/l, nitrite is harmful even in very […]
The belly sucker catfishes (Glyptothorax) are almost unknown in aquaristics. It is a very species-rich group (over 100 accepted plus probably still numerous undescribed species) of mostly small, current-loving catfishes. The extremely sparse care experiences with these catfishes show that they are (as with many stream fishes) sensitive animals, which tolerate neither stronger organic pollution […]
Among the numerous shrimp species that have gained a firm foothold in the hobby are two larger species of fan shrimp, namely Atyopsis moluccensis, the Moluccan mountain rock shrimp from Southeast Asia, and Atya gabonenis, the Gabon giant fan shrimp from West Africa. They grow relatively large (A. moluccensis approx. 9 cm, A. gabonensis approx. […]
From Brazil we received beautiful whiptail catfishes, which we thought at first sight to be Rineloricaria lanceolata, a species with a very wide distribution. The high proportion of reddish animals was striking. The majority of the fish are small, 3-4 cm long and marked like R. lanceolata, but there are a few adult specimens among […]
From Colombia we received a nice Corydoras species, which threw us into some confusion during identification. They were sent as C. armatus, a species described from the Rio Huallaga, a right-bank tributary of the Rio Maranon (the larger of the two headwaters of the Amazon) in Peru. C. armatus is a conspicuously high-backed species with […]
The Flying Fox, Epalzeorhynchos kalopterum (Epalzeorhynchos is neuter, so if the species name is an adjective – as in this case – it must end in the Latin neuter suffix -um), originates from Indonesia, Malaysia and Thailand, where it is a resident of flowing waters that carry deep dark brown black water. They are probably […]
Silver mollies are among the most popular livebearers. Most of the silver mollies in the trade are a breeding form of Poecilia latipinna. Since the species Poecilia latipinna, P. sphenops, P. mexicana and P. velifera can be crossed and color characteristics and certain fin shapes (e.g. lyratail) are transferred to the hybrid young, the desired […]
From a German breeder we received this extraordinarily attractive wild form of the swordtail. Unfortunately we could not find out where exactly and by whom these animals were collected. It could only be determined that they were originally brought from Yucatan (Mexico). As a distinction to the completely different looking X. hellerii “Yucatan” (see https://www.aquariumglaser.de/en/fish-archives/xiphophorus_hellerii_yucatan_en/) […]
Because of the enormous popularity of the butterfly cichlid or blue ram (Mikrogeophagus ramirezi), there are mainly offspring and breeding forms on the market. Also the wild-colored offsprings differ clearly from the wild species: they are considerably larger (4-5 cm body length without caudal fin compared to 2-3 cm with wild-caught fish) and at the […]
Oligolepis acutipennis is one of the most widespread gobies of the Indo-West Pacific. The species, which can grow up to 15 cm long, is distributed from South Africa via East Africa, the Persian Gulf, Madagascar, Indonesia and along the entire coast of Southeast Asia to Japan. From this wide distribution one can easily conclude that […]
Corydoras reynoldsi is a pretty cory catfish that has been described in 1960. It was collected in the Caquetà province, eastern Colombia. It remained unknown in the hobby quite long, as this area is far away from the usual collecting areas. In 1997 the cory enthusiasts became aware of another, quite similar species of Corydoras […]
The chocolate gourami (Sphaerichthys osphromenoides) still belongs to the legendary ornamental fish species. Although the species is common in the wild and other fish of the same habitat (e.g. harlequin barbs) do not cause significant problems in the aquarium, it is a gamble whether chocolate gouramis will do well there. Possibly this is related to […]
The Green panchax (Aplocheilus blockii) is one of the tiniest and most beautiful species of panchax in Asia. We were able once more to import the species from Kerala (South India). Its maximum length is around 3 cm, at least as far as wild collected specimens are concerned. Aquarium specimens may become a bit larger […]
This is one of the large river catfishes of Africa. We were able to import some specimens once more from Nigeria. However, the species has a very far distribution and is found in the Nile, most parts of West Africa and also in the rivers that flow through the savannahs and riparian forests of East […]
Now it is again season for the unfortunately so rarely available Pseudorinelepis sp. L95 from the Rio Demini. And what beautiful animals we got! All specimens are 25-30 cm long. For more information please see https://www.aquariumglaser.de/en/fish-archives/pseudorinelepis-sp-l95-2/ For our customers: the animals have code 26480-L 095-7 on our stocklist. Please note that we supply only wholesale. […]
For a long time this beautiful dwarf cichlid from the basin of the Rio Nanay in Peru sailed under the name “cf. juruensis” or “sp. Black Chin”. Only the scientific description of the species in 2012 put an end to the confusion. Great similarity exists to A. juruensis and A. cacatuoides. From both species living […]
The large-sized species of the spiny catfishes (Pimelodidae) belong as adult fishes to the desired food fishes and not less desired species for fans of predatory catfishes with giant aquariums. As juveniles, these animals often look completely different and have, for example, absurdly long fin processes. The Shovelnose catfishes of the genus Sorubim are with […]
Fishes of the genus Barilius are ecologically best compared to trout in the Indian region, where they do not naturally occur. Barilius thus prefer to live in clear waters with a gravelly bottom and some current. They are mostly seen in loose groups, they are not really schooling fish. They like to “play” among themselves, […]
The Hypancistrus catfishes with striped pattern are on the one hand a wonderful enrichment for the aquaristics, because they look beautiful, don’t grow too big and can be bred quite well, on the other hand they are constant cause for quarrel. Because in many cases it is hardly possible to determine them exactly. This is […]
The Yellow Congo Tetra (Alestopetersius caudalis) originates, as the name suggests, from the Congo. However, it is almost never traded as wild catch, because it can be bred very well. With a final length of about 6 cm it belongs to the smaller species of the Congo tetra relationship. In the course of its aquaristic […]
Mostly we receive the Indian Pearl Cichlid (Etroplus suratensis) as wild catch from South India (formerly also from Sri Lanka) or as German offspring from zoo aquariums. Now, for the first time, we have imported bred ones from Indonesia; some specimens of these offspring do not show a stripe pattern, but have an irregular bow […]
We were able to import the rare Red-eyed Deltatail-suckercat, Lasiancistrus heteracanthus, in small numbers from Peru. The species attains a total length of 15-18 cm. Besides the bright red eye the most striking feature of the species is the pretty brown-red lower lappet of the caudal fin. Lasiancistrus, in general, are good algae-eaters and fit […]
From the sailfin molly, Poecilia velifera, which originates in the hot coastal regions of Mexico, there are mostly cultivated forms in the trade: Golden, chocolate, leopard, dalmatian, black, etc.. The “green” wild form is much rarer, although they are very colorful animals. All sailfin mollies on the market are bred ones. The huge dorsal fin […]
From time to time we receive a very flat-bodied Ancistrus from the Orinoco drainage in Colombia and Venezuela under the name of A. ranunculus/L 34. However, this species does not exist there, A. ranunculus is only known from the Amazon tributaries Xingu and Tocantins/Araguaia; the Orinoco species is Ancistrus macrophthalmus, which has received the LDA […]
This week we received a good number of the interesting frogmouth catfishes of the species Chaca bankanensis from Sumatra. In contrast to the rather reddish animals we could import earlier (https://www.aquariumglaser.de/en/fish-archives/chaca_bankanensis_en/), this time they are rather brown-black colored, probably an origin-related color characteristic. Very interesting is that some animals have striking white colored eyes. At […]
The genus Curimatopsis comprised five described species until 2009 – now (2021) there are more than twice as many, namely 11! Curimatopsis can be divided into two major groups. First the C. macrolepis group with 6 species and second the C. evelynae group with 5 species. The best distinguishing feature of the two groups is […]
Already in 1894 the three-banded flag tetra (Hyphessobrycon heterorhabdus) was described scientifically; the animals on which the description was based came from the Brazilian state of Pará, more detailed information or illustrations are not available. From 1910 and in the 1920s, when the tetras advanced to the most popular aquarium fishes, also three-banded tetras came […]
Elephant fishes or mormyrids are very interesting and also entertaining fish. They communicate among themselves with electrical signals and have – similar to birds – a relatively well developed cerebellum. Their bizzare body shape makes them additionally interesting. However, they have little to offer in terms of color, mostly coming along in shades of brown […]
Only very rarely marbled swamp eels from South America are available. After a quite long time we now have a number of juveniles from Peru in stock. The species attains a maximum length of about 1.5 m. These very large individuals are always males, because swamp eels change their sex. Most of them are born […]
This beautiful Corydoras belongs to a scientifically undescribed species. It originates from the upper Rio Negro in Brazil. Because of the bright orange neck spot it is usually misidentified as Corydoras burgessi, which also comes from this region, especially as C. burgessi has a very variable pattern and there are also spotted colour variants of […]
It is and remains the oldest ornamental fish in the world: the goldfish (Carassius auratus) and its many cultivated forms. It has been propagated and kept by humans for about 1,000 years. Many consider goldfish to be garden pond fish, especially the varieties with “nomal”, wild fish-like body types. This is quite true, and they […]
The African Mono is widely distributed along the tropical Atlantic coast of Africa. As a completely euryhaline fish, it can freely change between fresh, brackish and seawater; it prefers to stay in brackish water. In its native range M. sebae is a common fish and is caught there for food. In the past, aquaristic needs […]
The attractive Apistogramma sp. Oregon comes from the wider surroundings of Iquitos in Peru. Don’t ask us why this one is called “Oregon” – we don’t know that either. It belongs to the closer relationship of A. nijsseni, but differs clearly from this species by the bulky body structure, the large tail spot and a […]
Just as L-numbers are assigned for undetermined loricariids, C- and CW-numbers are assigned for undetermined Corydoras. One of the first species to receive such a number was Corydoras parallelus, which was assigned the number C2 in 1993. In the same year Burgess described it as C. parallelus. The species originates from the upper Rio Negro […]
There are two species of catfish in South America that look like siblings: Leiarus marmoratus (called “Achara” by the natives) and Leiarius (formerly: Perrunichthys) perruno. Both species attain a length of about 60 cm, have the very same leopard pattern and the long, ringed whiskers. But there does exist an easily recognizable difference: Leiarius marmoratus […]
