Siniperca chuatsi is a large fish for display aquariums. The maximum length reported to date is 70 cm, at which point the animal weighs around 8 kg. Of course, most specimens remain significantly smaller, but Siniperca chuatsi is still only suitable for normal aquariums as a young fish for a limited time. Siniperca are obligate […]
The genus Labeo plays hardly any role in aquatics; most species grow large (30-50 cm), have little to offer in terms of color, and are also considered quarrelsome. The smaller and more colorful species formerly classified as Labeo, such as the redtail shark, are currently classified in the genus Epalzeorhynchos. True Labeo species are found […]
From a geological perspective, we are currently in an ice age – despite global warming and its terrible consequences. This means that both polar ice caps are frozen. However, within the ice age, we are living in a warm period called the interglacial period. It began about 11,700 years ago. Before that, large parts of […]
The gold barb is a breed that originated from a barb closely related to the chinese barb (Barbodes semifasciolatus). However, no one knows for sure; the entire Barbodes genus is in dire need of revision. The gold barb was developed in the 1950s by an aquarist named Thomas Schubert from Camden, New Jersey (USA), which […]
Celestichthys erythromicron, which is endemic to Inle Lake in Burma, i.e. only found there, is a tiny aquarium fish. It reaches a maximum length of 3 cm when fully grown. The only complicated thing about this species is actually its name. It was originally described as Microrasbora erythromicron. However, it then became apparent that it […]
The classification of the genus of African alestid characins is the subject of ongoing debate, with no end in sight. There is constant back and forth, especially with regard to the Congo characins, which are of some importance in aquariums. Just recently, in the latest checklist of characins (Toledo-Piza et al, 2024), P. bleheri, which […]
The Port Hoplo Megalechis thoracata – still known to many by its old name Hoplosternum thoracatum – is one of the oldest aquarium fish. It really only has one disadvantage, namely that it grows to a considerable size, reaching a length of around 15 cm (sometimes even more). Despite its size, however, it has a […]
We regularly have beautiful offspring of this cute dwarf cichlid in stock. Wild-caught specimens are very rare on the market. Males of this species grow to about 6 cm in length, while females remain smaller. This makes this Nanochromis one of the smallest cichlids in existence. The fish originally comes from the Lac Mai Ndombe […]
There is no consensus on the systematic position of the livebearing toothcarps living on the Caribbean islands. Based on anatomical characteristics, the genus Limia was long considered synonymous with Poecilia, but they have so many unique characteristics that Limia was almost always referred to as a subgenus. However, more recent studies, particularly those based on […]
The genus Gymnogeophagus comprises medium-sized earth-eaters from the southern part of South America. Most species grow to a length of 10-15 cm, some up to 20 cm. Almost all of them are beautiful animals. Of the 20 currently accepted species, only 8 were scientifically described before 2000, which clearly shows that distinguishing between the species […]
Rice fish, or medakas, have a long tradition in aquariums. As early as the 19th century, so-called “gold haplochilus” – nothing more than a yellow breed of the Japanese rice fish, Oryzias latipes – were exported to Europe as ornamental fish, making them one of the very first imported exotic ornamental fish species. However, they […]
In southern India lies the ancient Deccan Plateau, which was formed when India was still part of Africa. Numerous small rivers flow directly into the Indian Ocean from here, and due to their geographical isolation, many of these rivers have developed their own color variations, subspecies, or species of freshwater fish. Barbs and loaches in […]
We occasionally receive the magnificent Satanoperca daemon, mostly from Colombia. The species is widespread and common throughout the Rio Negro region, but it is sensitive and therefore only available from the most experienced suppliers. The “three-spot daemon” is one of the most beautiful cichlids in South America and one of the most peaceful. With these […]
The dwarf cichlids of the genus Nannacara are found along the Atlantic coast of South America from Brazil to Venezuela. The easternmost species is N. taenia (see https://www.aquariumglaser.de/en/25-perchlike-fishes/nannacara-taenia/), which is also the smallest species of the genus. To the west, this is followed by Nannacara aureocephalus, the largest species of the genus. Its range covers […]
Pangasius spp. (shark catfish) are huge edible fish that feed largely on a vegetarian diet and have low water quality requirements. This makes them extremely well suited for aquaculture in tropical regions. These fish farms are where the cute babies that still regularly appear on the ornamental fish market come from. As long as they […]
In 2008, while examining a newly imported species (previously referred to by us as Boehlkea sp. “Sky Blue”), Dr. Axel Zarske discovered that it was actually Boehlkea fredcochui. The fish that had been referred to as B. fredcochui for decades, on the other hand, represented a species of the genus Knodus that had not yet […]
Hoplisoma sterbai (formerly: Corydoras sterbai, see https://www.aquariumglaser.de/en/10-catfishes/corydoras-sterbai-wild-4/) from the Rio Guapore basin in Brazil and Bolivia is at the top of the list of all-time favorites among armored catfish. The species is available year-round as captive-bred and occasionally also as wild-caught, and there is even an albino breeding form of these animals. The related long-snouted […]
We have this beautiful killifish in our stock as offspring; there are no exports from the animals’ original homeland – Gabon and Equatorial Guinea. The species was scientifically described as early as 1911 and has been kept and bred in aquariums since 1961. Unfortunately, killifish still have a reputation for being particularly sensitive, short-lived, and […]
For several years now, the first exotic aquarium fish after the goldfish—the paradise fish (Macropodus)—has been enjoying renewed attention. This is partly because new interesting wild forms have been discovered, but also because breeders are putting more effort into the animals again and offering high-quality specimens. Macropodus species have been crossed in aquariums since the […]
The discovery of Iriatherina werneri in 1973 by two traveling aquarists in rice fields near the city of Merauke in New Guinea was a sensation at the time. The animals were scientifically described in 1974 and named in honor of one of the discoverers. Since there were no ornamental fish exports from New Guinea at […]
We can offer a very small number of Hypsolebias faouri, which was only scientifically described in 2016. It is one of the rarest fish in the world. Of course, all animals on the market in this case are captive-bred specimens. What makes a fish rare? The adjective “rare” can mean many things. Rare on the […]
Since 2018, a relatively small species of tetra from the central Congo Basin has been causing quite a stir: Phenacogrammus sp. “Fantastique.” However, very little literature has been published on these animals to date, which is somewhat surprising given their small size (for an African alestid) and the beautiful coloration of the males, at least […]
In 1992, W. L. Fink and A. Machado-Allison described two piranha species of the genus Pristobrycon from locations in the Rio Atabapo basin (Venezuela): P. careospinus and P. maculipinnis. The two species differ in color. While P. maculipinnis has small dots on its body and spots on its vertical fins, the fins of P. careospinus […]
The three-banded flag tetra, Hyphessobrycon heterorhabdus, was once one of the most sought-after small tetras. When tetras were very fashionable – in the 1950s to 1970s – this species was classified as a “problem fish” because it did not reproduce without tricks and gimmicks. However, keeping this species without breeding intentions was completely problem-free. Today, […]
We often find that the fish species that are most commonly found in stores are not yet posted on our website. This is, of course, because there are always so many new and exciting species to introduce, but admittedly, even the supposedly old ones still have a lot to offer! Danio frankei appeared on the […]
Until relatively recently, the magnificent large-growing Andinoacara species were classified in the genus Aequidens. The genus Andinoacara comprises a total of eight recognized species. Three large-growing species—A. blombergi, A. rivulatus, and A. stalsbergi—form a species complex. These three species can therefore be relatively easily confused with one another. The easiest way to tell them apart […]
In aquarium science, there are always fish that are shrouded in legend. One of these is definitely Hoplisoma evelynae, which was described as early as 1963 based on a single specimen collected by Axelrod in the upper Rio Solimoes region (the name given to the Amazon above its confluence with the Rio Negro). For some […]
Members of the Sewellia genus are also commonly referred to as “splendid hillstream loaches” because their markings are often very contrasting. However, there are also species with plain coloring, such as the most recently scientifically described species, S. pudens Kottelat, 2025. A total of 15 Sewellia species have been named, but it is difficult to […]
One of the most beautiful African labyrinth fish is the leopard bush fish, Ctenopoma acutirostre, which grows to a length of around 15-20 cm. It is native to the Congo and is usually collected from Stanley Pool for aquariums. There they live during the day under the floating meadows of water hyacinths (Eichhornia crassipes). Occasionally, […]
The Brazilian state of Amapá is located in the far northeast of Brazil on the Atlantic Ocean. It is particularly interesting from a zoogeographical point of view because its rivers – such as the large Rio Araguari river system – are home to fish species that are otherwise only found in neighboring French Guiana in […]
The African glass catfish, Parailia pellucida, is a magnificent aquarium fish, but strangely enough, it is virtually unknown among hobbyists. Yet this species is almost always available. We import it regularly from Nigeria. The African glass catfish is not closely related to the Asian glass catfish (most commonly found in aquariums: Kryptopterus vitreolus, see https://www.aquariumglaser.de/en/10-catfishes/kryptopterus-vitreolus-2/). […]
Betta macrostoma is undoubtedly one of the most beautiful fighting fish—and one of the most sensitive. There is hardly any other fish species that is as susceptible to bacterial infections as this one. Many breeders have no choice but to run their tanks continuously through UV filters. A little tip: clay dissolved in the water […]
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 […]
The Malawi eyebiter Dimidiochromis compressiceps (formerly: Haplochromis c.) is one of the most unusual cichlid species in Lake Malawi. It is a predatory fish, with males reaching up to 25 cm in length and females up to 20 cm. In 1966, the species was mistakenly considered to be a specialized eye eater. However, this behavior […]
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 […]
A pretty new tetra is Inpaichthys luizae, a species that was only formally described in January 2025. It occurs in areas that are hardly accessible to scientists and commercial fishermen because they are privately owned. What is known, however, is that these locations are tributaries of the Rio dos Peixes in Brazil, which in turn […]
The snail cichlids of Lake Tanganyika continue to enjoy unbroken popularity. Their comical breeding behavior, in which they guard their spawn and young in empty snail shells, never ceases to fascinate. It is particularly interesting to observe an entire colony of these fish inhabiting what is essentially a snail shell city. In most snail cichlids, […]
The genera Sturisoma (15 scientifically described and accepted species, east of the Andes = cis-Andean) and Sturisomatichthys (13 scientifically described and accepted species, west of the Andes = trans-Andean) are referred to in German as Störwelse (= sturgeon catfish), in English as Royal Farlowellas. Sturisoma nigrirostrum from Peru is imported more or less regularly. The […]
Hoplisoma sp. C3 (previously classified in the collective genus Corydoras) is a very beautiful armored catfish, especially adolescent specimens, because they often develop high dorsal fins at this age. However, this is a temporary phenomenon that can sometimes also be observed in Hoplisoma metae. Only fully adult males of C3 – the animals grow to […]
Polycentropsis abbreviata means roughly translated “short and similar to Polycentrus”. In fact the African Leaffish looks very similar to Polycentrus schomburgkii from South America. Both species witness the existence of the ancient super continent Gondwana. Gondwana was formed from what is now South America, Africa, India, Australia, and Antarctica. South America drifted away from Gondwana […]
Oriximiná is located on the Rio Trombetas in the Brazilian state of Pará. From there we receive fantastic blue discus in magnificent colors. For the tiresome question of species classification in discus, see here: https://www.aquariumglaser.de/en/fisharchive/the-scientific-species-name-of-discus-cichlids-an-open-question/ Blue discus are generally very variable in color (“polychromatic”), even those from the same location. That is why the “Oriximina […]
In 1982, Gerald R. Allen and Norbert J. Cross published the first modern comprehensive overview of the rainbowfish known at that time. By that time, Allen had already described 12 new species since 1978. When he began systematically studying rainbowfish, only 19 Melanotaenia species had been described between 1843 and 1978, a period of 135 […]
We have received a very small number of one of the smallest and definitely one of the prettiest loaches in Thailand: Schistura pridii. These cute black and white dwarfs grow to only 3-4.5 cm in length. As far as known, this species, which was only scientifically described in 2003, only occurs in shallow, fast-flowing forest […]
We received a species of mormyrid from Nigeria that we had not seen for years: Brienomyrus brachyistius. This comparatively small species, with a maximum length of 17.5 cm, but usually remaining significantly smaller at 10-12 cm, is a close relative of the comparatively frequently imported species B. niger (see https://www.aquariumglaser.de/en/03-bony-tongues/brienomyrus_niger_en-2/). These playful, intelligent fish are […]
In 2002, a deep red dwarf pencil fish from Peru was imported under the names Nannostomus marginatus “Purple” or N. marginatus “Red.” Axel Zarske from the Senckenberg Natural History Collections Dresden, Museum of Zoology formally described this species in 2009 as Nannostomus rubrocaudatus. We had imported the type specimens on which the scientific description is […]
Breeding marbled swordtails on a red background is a challenge. With the “Black Tiger,” it has succeeded. Each “Black Tiger” has its own unique body markings. Until now, these swordtails have almost exclusively been offered with a whitish body color (in which case they are referred to as marble). Many of the black scales have […]
Aquarium Glaser has once again received the smallest known Danio species, which is closely related to the zebrafish (Danio rerio), from Burma. Danio tinwini was first imported in 2005, at that time still known as Danio sp. “Panther.” The species, which was scientifically described in 2009, grows to only about 2-3 cm in length and […]
On the Guiana Shield of South America – a very old geological formation that covers large parts of Venezuela, Guyana, French Guiana, Suriname, and parts of Brazil and Colombia – there is a group of small, closely related species of armored catfish that look so similar that they were sometimes considered synonymous with each other: […]
We received from Thailand this wonderful sport of the Blue Loach (Yasuhikotakia modesta, formerly known as Botia modesta). The species is well known for its variability. Most often the fish are blue with bright red fins (see https://www.aquariumglaser.de/en/07-carp-like-fishes-1-loaches/yasuhikotakia-modesta-2-3/, there you will also find lots more information about the species.), but the body colour can vary […]
The genus Garra is incredibly diverse and confusing. Currently (December 2025), 277 species names are associated with Garra, of which 171 are generally considered valid. The distribution area is huge and extends across parts of Africa and large parts of Asia; they can be found basically anywhere where it does not get too cold in […]
The harlequin barb, Trigonostigma heteromorpha (formerly Rasbora h.), is one of the most important aquarium fish of all. For this reason, it is traded almost exclusively as a captive-bred species, as the availability of wild-caught fish fluctuates greatly due to seasonal conditions (during the rainy season, the natural habitats are often inaccessible for months). In […]
Finally we were able to import again a small number of the extremely rarely offered long snouted Corydoras amapaensis. The distribution range of this extraordinary species lies in the Oyapock and Amapari river basins in the state of Amapá in Brazil and in French Guiana. The species is highly variable in respect of coloration. The […]
One of the largest Asian barbs imported for aquarium keeping is Barbonymus schwanefeldii. It used to be known formerly as Barbus. This species, native to Borneo, Malaysia, and Thailand, grows up to 35 cm long. The red coloration of the tail fin is wonderful and is found in this intensity in hardly any other fish. […]
So-called gold tetras are found in many species of characins in South America. Usually, only a few fish in a school are affected by the phenomenon in which guanine, the substance responsible for the shiny silver or gold glitter effect of the fish scales, is secreted at a much higher rate than usual. We explain […]
The tailspot bushfish (Ctenopoma kingsleyae) originates from wooded areas in western Africa. It was one of the first labyrinth fish exported from Africa for aquariums. The first specimens from the lower Niger region arrived in Germany as early as 1912. Strangely enough, this calm, peaceful species was described at the time as very aggressive and […]
Nannostomus mortenthaleri from Peru (Rio Nany tributary in the province of Loreto) was the most beautiful new discovery in aquatics in 2000. The close relative of the dwarf pencil, N. marginatus, remains small – approx. 4 cm – and is breathtakingly beautiful in color in the male sex. At least sometimes. Because apart from anatomical […]
Black and white goldfish are referred to as “magpie-colored” in breeding circles, fish with telescope eyes as “Demekin,” and those with a simple double tail fin as “butterfly tail.” An Oranda, on the other hand, is a goldfish with a hood, in breeding terms. Accordingly, the cute pandas that we were finally able to import […]
At the beginning of 2024, this snakehead species, which had long been known in the hobby as Channa sp. Fire & Ice, was scientifically described as Channa pyrophthalmus. So far, it is only known from the extreme southern border area between Burma and Thailand. We are currently able to offer this small and colorful Channa […]
For the first time, we are able to offer a small number of this “new” variant of the well-known Apistogramma agassizii. They were originally by-catches of the magnificent Putumayo variant of A. bitaeniata from Peru (see https://www.aquariumglaser.de/en/fisharchive/apistogramma-bitaeniata-putumayo-4/). We raised a few specimens to see what would become of them, and we can only say: it […]
This species of pygmy sunfish was only formally described scientifically in 2009. It originates from Florida and Alabama, where it occurs alongside (but not together with) the very similar species E. okefenokee. Like all pygmy sunfish, they are small fish, with males reaching a maximum total length of 3 cm; females remain smaller. The sexes […]
Hillstream loaches belong to the loach family. The most beautiful representatives are found in the genus Homaloptera. Until a few years ago, this genus was very broadly defined; 72 species were described as Homaloptera spp. Today, however, the definition of the genus is much narrower and only six species are assigned to the genus Homaloptera: […]
One of the first tetras ever imported for aquariums is Hyphessobrycon flammeus. Since its first import in 1924, the species has never disappeared from aquariums, as it is easy to breed and the fish are very productive. Due to its origin (the area around Rio de Janeiro in Brazil) and its pretty red color, the […]
There are four species of lungfish in Africa, some of which are difficult to distinguish from one another. The situation in Congo is particularly confusing (see https://www.aquariumglaser.de/en/29-lungfishes/lungfishes-from-the-congo/). Only the species Protopterus dolloi is always easy to recognize due to its elongated body shape. The surest way to distinguish between the three species Protopterus aethiopicus, P. […]
The rummynose tetras are a beautiful eye-catcher for any aquarium with peaceful fish. A shoal of these animals, and there should always be 15 – 20 specimens if possible, delights every observer because these animals really do swim permanently in a shoal; the vast majority of so-called shoal fish among aquarium fish do not do […]
The colorful rock cichlids (Mbuna) of Lake Malawi are mainly kept for their bright colors, but they actually have more to offer in terms of behavior than just looking good. Maylandia sp. Daktari—a species not yet scientifically described—occurs only in a relatively small area in four populations; two of these populations are indistinguishable in appearance. […]
This attractive squeaker catfish originates from the lower Congo (for example in the Pool Malebo area, formerly known as Stanley Pool). With a final size of around 20 cm, it is one of the medium-sized species of the genus. In the past, this catfish was considered to be as sensational as the zebra catfish (L46, […]
The fishing season for the beautiful Golden Nugget catfish of the genus Baryancistrus lasts from around the end of May to the end of September. Due to the varying sizes of the spots on their bodies and the varying widths of the fin edges on their dorsal and caudal fins, as well as the varying […]
At present the small tetras of South America experience a new boom. Numerous species have been and are being described scientifically. Thus also the ornamental fish collectors leave their beaten tracks and look for these animals, particularly since initially peppered prices are paid for the novelties. Naturally, such a thing only works for a short […]
This small (5-6 cm) mouthbrooding species from Thailand is a very nice addition to the assortment of wild collected Betta we occasionally have in stock. Betta simplex is a close relative to the species Betta picta from Java, Betta falx from Sumatra, and Betta taeniata from Borneo. All the mentioned species share obviously the same […]
The global loss of biodiversity, i.e., species diversity, is terrible. People who are particularly interested in nature, and this includes aquarists in particular, feel the extinction of species almost as physical pain. Small fish species are among the few organisms that are very well suited for conservation breeding over a very long period of time […]
The large (around 60 cm) spiny eel Mastacembelus unicolor was scientifically recorded early on. The two researchers Kuhl and van Hasselt discovered it in the western part of Java during their stay there from 1820 to 1823 and also made a drawing of the animal. The two paid for their thirst for knowledge with their […]
With 133 species, the squeaker catfish (Synodontis) inhabit practically the entire African continent. The smallest species grow to 6-7 cm in length, the largest to 60-70 cm. They play a very minor role in aquariums. Only the Upside-Down catfish (Synodontis nigriventris) and a few species from Lake Tanganyika are true aquarium fish with a larger […]
The genus Curimata currently comprises 13 species; only one of these occasionally finds its way into our aquariums, namely Curimata vittata. The other species simply offer no incentive to keep them. They are shiny silver-colored animals that can reach a length of 15-20 cm and feed mainly on plant material. Curimata vittata also reaches this […]
The miniature lampeyes of the genus Fluviphylax are the smallest relatives of killifish. When fully grown, their body length is less than 2 cm standard length (i.e., without the tail fin), usually around 1.5 cm. Until recently, these dwarfs were only known from Brazil, from where we were occasionally able to import them, but that […]
There are three species of Apistogramma that even a very experienced Apistogramma enthusiast cannot reliably distinguish from one another: A. uaupesi (scientifically described in 1980 from the Rio Uaupes in Brazil, previously given the common name “segelflossen ( = sailfin) apistogramma” by Schmettkamp, later referred to by various authors as “red-wedge ( = rotkeil)” or […]
We received four larger (10-15 cm) banjo catfish from Colombia, which turned out to be four different species. The two Xyliphius specimens were identified relatively quickly; one is a specimen of X. lepturus and the other is an almost entirely black specimen of X. melanurus (see https://www.aquariumglaser.de/fischarchiv/xyliphius-cf-lepturus-und-x-cf-melanurus/). The two “real” Bunocephalus were more difficult to […]
Banjo catfish (Bunocephalus) are extremely common in nature. That’s why we always have them in stock. We usually refer to these animals as Bunocephalus coracoideus, which may be correct in many cases. But when you look at such a swarm of banjo catfish, you notice that there are always other species mixed in. As a […]
Whenever one of our suppliers offers a “new variety,” we order a box to see what it is. However, we know from experience that the term “new variety” is often used very flexibly. The spectrum ranges from “old news, but new to our list” to “wow, we’ve never seen anything like this before.” This time […]
In 2009, we successfully imported a large, beautiful armored catfish from the Rio Jutai in Brazil for the first time. At the time, we referred to the animals as Corydoras sp. aff. armatus because their particularly high dorsal fin and general body shape were very reminiscent of C. armatus. However, C. armatus (current name: Hoplisoma […]
The city of Niété is located in the southern part of Cameroon and is part of the Océan department in the South Province. It is traversed by the Nyété River, which is a tributary of the Lobé River. The beautiful Pelvicachromis kribensis occurs there in a special color variant known in the hobby as “Nyété.” […]
The roundtail or Chinese paradise fish (Macropodus ocellatus, formerly M. chinensis) is a fish for connoisseurs and experts. For connoisseurs because it is extremely inconspicuous in its plain plumage – i.e. as a rule in the dealer’s tank. Those who are not familiar with it will therefore usually not buy it. But connoisseurs know: in […]
From Colombia (Rio Meta basin), we have obtained Saxatilia sveni, which is very rarely imported, together with Crenicichla (Batrachops) sp. “Belly Crawler” ( = C. sp. aff. sedentaria), which also occurs there. This representative of the former Crenicichla saxatilis group, which is currently grouped in a separate genus Saxatilia, grows to a considerable size, 25-30 […]
The genus Crenicichla was once the largest of all cichlid genera, with 139 scientifically described species, 93 of which are generally recognized as valid species. In addition, there are a large number of species that are already known to aquarists but have not yet been scientifically studied. The genus has since been subdivided (see https://www.aquariumglaser.de/en/25-perchlike-fishes/the-crenicichla-have-been-reclassified/). […]
We consider the import of this beautiful new Hoplisoma to be sensational. According to the supplier, it comes from a small tributary of the Rio Tomo in eastern Colombia. The fishermen refer to this tributary as Cano Negro. The water is described as “crystal clear.” The Rio Tomo itself is a tributary of the Orinoco, […]
Currently (September 2025), 28 species are assigned to this genus. The genus was established in 1907 by Eigenmann for the species Tetragonopterus pectinatus, described in 1870 by Cope from Peru (Pebas). Cope’s description was not accompanied by any illustration, so Fowler drew the holotype in 1907, which he classified in the genus Astyanax. Based on […]
Imagine you have a first import and don’t even realize it! That’s what’s happening to us right now with a tetra. We received some very beautiful, large Hemigrammus coeruleus from Colombia. At least, that’s what we thought. By chance, Peter and Martin Hoffmann, from whom we often and gladly receive rare tetra offspring, needed a […]
In the 1990s, when Brazil’s large river cichlids experienced something of a boom, four species from the former collective genus Crenicichla also arrived in Europe for the first time. Due to the lack of a scientific name, they were designated Crenicichla sp. Xingu I – IV. All four grow to a considerable size for ornamental […]
In old aquarium books, you can still read that the males of the Least Killifish (Heterandria formosa) could claim the title of “smallest fish in the world.” They grow to a maximum length of only about 2 cm, which is significantly smaller than the females, which grow to a length of up to 3.5 cm. […]
This dwarf goby, a relative of the of neon gobies (Stiphodon), was scientifically described in 1999. To date, the species is only known from coastal rivers in western New Guinea (Irian Jaya). However, since it undergoes its juvenile development in the sea, like all sicydiine gobies, it is more than likely that it is much […]
We have once again received offspring of this beautiful rainbow fish. For basic information, please refer to this post: https://www.aquariumglaser.de/en/17-rainbow-fishes-and-co/glossolepis_dorityi_lake_nenggwambu__en/ Unfortunately, it is quite likely that Glossolepis dorityi, which was only scientifically described in 2001, is already extinct in the wild. We quote here from the entry in the International Red List (IUCN): “This species […]
It is not without reason that guppys are among the most popular ornamental fish in the world, ranking high in the top ten. The play of colors is almost endless. This applies to the “classic” guppy Poecilia reticulata as well as its slightly smaller cousin P. wingei, the Endler guppy, and the countless hybrids that […]
Banjo catfish (Bunocephalus) are extremely common in nature. That’s why we always have them in stock. We usually refer to these animals as Bunocephalus coracoideus, which may be correct in many cases. But when you look at such a swarm of banjo catfish, you notice that there are always other species mixed in. As a […]
Many good aquarium fish have come to us from the extremely species-rich genus Garra. The “doctor fish” Garra rufa (https://www.aquariumglaser.de/en/fisharchive/garra-rufa-2/), Garra flavatra (https://www.aquariumglaser.de/en/08-carp-like-fishes-2-barbs-minnows-carps-goldfish-etc/garra_flavatra_en/) is very pretty, and Garra panitvongi (https://www.aquariumglaser.de/en/fisharchive/garra-panitvongi-sp-red-tail-2/) is bizarre and beautiful. Now we received two specimens of a Garra species as samples, whose beauty took our breath away. This is Garra qiaojiensis, […]
The discovery of a new genus of driftwood catfish—Spinipterus—is quite sensational. In 2011, the first species of the newly described genus (S. acsi) was described and the new genus was established for it. In 2019, the second species (S. moijiri) was added, which is significantly more attractive in appearance and displays a beautiful jaguar pattern […]
The three-banded pencilfish, Nannostomus trifasciatus, is one of the most popular ornamental fish.
