25. Perchlike fishes (866)

  • Betta unimaculata

    7. June 2024

    Modern labyrinth fish science began in the 1980s. At that time, enthusiastic labyrinth fish enthusiasts joined together to form international associations. The world opened up to travelers and areas in Southeast Asia could be visited that had previously only been known from maps. One of the first Betta species to enter the hobby at that […]

  • Apistogramma norberti

    6. May 2024

    The 1990s were a decade in which many new dwarf cichlid species were discovered and scientifically described. This was made possible by the combination of good travel opportunities and tolerant export policies, the emerging Internet and the resulting considerably simplified global communication. Apistogramma noberti, a species from Peru that was scientifically described in 1991, was […]

  • Heros sp. Turquoise Lago Juá

    3. May 2024

    The genus Heros is in urgent need of scientific revision. The current five generally recognized species only represent a small part of the populations now known. It is often almost impossible to choose a reliable species name, which is why in many cases it is now simply omitted. They are called Heros sp. and an […]

  • Pterophyllum “Zebra”

    3. May 2024

    We do not know exactly when and where the zebra scalar was bred. In his monograph on angelfish, completed in 1977 but not printed until 1979, Paepke states that he was unable to find any sources. At this time, there were already several breeding lines of the zebra scalar, whose characteristic breed feature is the […]

  • Amatitlania (formerly Cichlasoma) nigrofasciata Marble

    3. May 2024

    The Convict cichlid Amatitlania (formerly Cichlasoma) nigrofasciata is no longer a novelty: it has been kept and bred in aquaria since 1939. The first aquarium specimens of this fish, which is widely distributed in Central America, came from Lakes Atitlan and Amatitlan in Guatemala. The genus to which the greenfin cichlid currently belongs was named […]

  • Vieja zonata

    23. April 2024

    We mistakenly received a Central American cichlid species from South East Asia under the name “Cichlasoma cyanoguttata”. After the 5-6 cm long fish had swum in a little, we went about identifying them and came to the conclusion that they were probably a Vieja species, most likely V. zonata. In such cases, however, it is […]

  • Pterophyllum “Platinum”

    4. April 2024

    White animals exert a special attraction on many people. In myths and fairy tales, it is often white individuals of a wild animal species that have magical properties. This explains why white rabbits, white pigeons, white mice etc. also have a special status among pets, and ornamental fish are no exception. The loss of color […]

  • Andinoacara pulcher “Neon Blue”

    28. March 2024

    Exactly 10 years ago, a new star appeared in the ornamental fish sky. A beautiful sky-blue (to stay in the picture) cichlid conquered the world. It was first offered to us in February 2014 under the name “Nannacara Neon Blue” from Singapore. However, it was clear from the outset that it was not a representative […]

  • Pseudosphromenus cupanus

    25. March 2024

    What are the reasons for choosing this or that fish for your home aquarium? In the beginning, it’s probably basically the colors. Over time, you develop a feeling for the wealth of shapes in the realm of fish, then swimming behavior and body shape are added to the selection criteria. And finally, you delve deeper […]

  • Astronotus Red, Albino Red and Red Chili

    20. March 2024

    Oscars (Astronotus) are naturally very variable in color. In addition to wild-colored animals, cultivated forms have also enjoyed great popularity for decades. Why is the Oscar called Oscar? To be honest, we don’t really know. But it is certain that the name originated in the USA. In 1936, an article by E. W. Clarke on […]

  • Pterophyllum “California”

    20. March 2024

    The freshwater angelfish (Pterophyllum) is one of the most popular ornamental fish of all. The species name Pterophyllum scalare is usually chosen for the cultivated forms, although this does not describe the situation correctly from a scientific point of view. The cultivated forms, which were mainly created in the 1940s to 1960s, are partly based […]

  • Geophagus taeniopareius

    15. March 2024

    In 1981, the first report appeared on a Geophagus species imported as by-catch, which the author, Rainer Stawikowski, initially referred to as the “Yellow Cheek-Stripe Eartheater“. The relatively slender species is very much out of the usual range of Geophagus, both physically and in terms of brood care behavior. Nevertheless, it took until 1992 for […]

  • Pterophyllum sp. “Rio Nanay” bred

    15. March 2024

    Like so many cichlids, angelfish also develop different-looking forms within their large distribution area. Whether these forms are classified as independent species, as subspecies or as color variants is ultimately a matter of taste and a philosophical issue. There are also individual differences within each population; in the case of the angelfish of the Rio […]

  • Macropodus spechti “Royal Blue”

    8. March 2024

    We have again received a nice number of beautiful domestic offspring of this extraordinarily beautiful black paradise fish (Macropodus spechti “Royal Blue”). For the history of this variant see https://www.aquariumglaser.de/en/25-perchlike-fishes/macropodus-spechti-royal-blue-2/ In the meantime, the fish have been further developed in terms of breeding and are preferably bred with animals that – very similar to Belontia […]

  • Discus Special (3): Brown/blue Discus

    8. March 2024

    Small wild-caught fish Discus cichlids, like all cichlids, only develop their full coloration when they are largely mature (i.e. approx. 15 cm long in the case of discus). This is generally known and one of the reasons for the popularity of Asian color breeds, as they already show their full color at lengths of 7-9 […]

  • Discus Special (2): Discus Green 7-9 cm

    8. March 2024

    Small wild-caught fish Discus cichlids, like all cichlids, only develop their full coloration when they are largely mature (i.e. approx. 15 cm long in the case of discus). This is generally known and one of the reasons for the popularity of Asian color breeds, as they already show their full color at lengths of 7-9 […]

  • Discus Special (1): Discus Heckel Rio Negro 7-9 cm

    29. February 2024

    Small wild-caught fish Discus cichlids, like all cichlids, only develop their full coloration when they are largely mature (i.e. approx. 15 cm long in the case of discus). This is generally known and one of the reasons for the popularity of Asian color breeds, as they already show their full color at lengths of 7-9 […]

  • The scientific species name of discus cichlids: an open question

    20. February 2024

    The question of which scientific species names should be given to the various discus cichlids is a controversial one. There is agreement that all Symphysodon populations are relatively closely related to each other and that preserved specimens cannot be identified with certainty without color and location; the only exception is the Heckel discus (Symphysodon discus), […]

  • Apistogramma sp. Nanay

    26. January 2024

    The species characteristics of this dwarf cichlid from Peru are: distinct underbelly stripes, an orange “axillary spot” (the attachment point of the pectoral fin is intensely orange in color), a more or less distinct orange zone on the belly and a tail fin that is tipped at the top and bottom in old, fully developed […]

  • Mugilogobius myxodermus

    22. January 2024

    Small freshwater gobies have recently attracted the attention of more and more scientists and, as a result, new species are constantly being discovered and old, almost forgotten species rediscovered. The genus Mugilogobius currently comprises around 30 species. It is not possible to be more precise because individual species are placed in different genera by different […]

  • Channa pulchra

    19. January 2024

    Sometimes supposedly small details are decisive, for example when it comes to species differences. There are two species of snakehead (Channa) that occur geographically close to each other in Burma (Rakhine State): Channa pulchra and Channa ornatipinnis. Both look quite similar and grow to a similar size (20-25 cm), but they differ considerably in their […]

  • Pseudetroplus maculatus (formerly: Etroplus maculatus)

    15. January 2024

    The orange chromide, Pseudetroplus maculatus, is a well-known aquarium fish and has not disappeared from the tanks of enthusiasts since it was first introduced. Recent studies indicate that the three species of cichlids from India (Pseudetroplus and Etroplus) are not so closely related to the cichlids (Cichlidae), but rather to the damselfishes (Pomacentridae). However, this […]

  • Cleithracara maronii KOUROU

    12. January 2024

    The Keyhole cichlid (Cleithracara maronii, formerly Aequidens maronii) is a well-known aquarium fish that has only rarely been imported to Europe as a wild catch since its first import in 1936. The demand is covered by captive breeding. Although the species has no striking colors – the very varied pattern consists of brown, grey, beige […]

  • Rhinogobius zhoui

    5. January 2024

    This freshwater goby, which attains a maximum length of 4-5 cm, is one of the most attractive discoveries of ornamental fish of the last years. However, in the beginning the fish were extremely expensive. Currently we can offer them for a comparably moderate price. Rhinogobius zhoui originates from China. In the natural habitat – brooks […]

  • Parambassis siamensis

    15. December 2023

    Formerly this species of glass perch was the most common found in the trade. It has a very wide distribution through Thailand, Vietnam, Cambodia, and Laos. However, Parambassis siamensis was most often mis-identified and traded under the name “Chanda wolffii”. P. siamensis is very similar to the Indian species P. ranga. Both are distinguished by […]

  • Rubricatochromis sp. Neon

    13. December 2023

    If aquaristics were exclusively about colors, there would hardly be any need for species other than Rubricatochromis. The “Neon” is probably a breeding form created by crossing and selection, in which the blue iridescent spots, which most red jewel cichlids have, are combined to form larger areas. In terms of body shape, Hemichromis sp. Neon […]

  • Boesemania microlepis

    11. December 2023

    The drums (Sciaenidae), to which Boesemania microlepis belongs, are mainly known from the sea. Only a few of the approximately 300 species live permanently or occasionally in freshwater. These fish are known as “drums” because they make a very audible sound. Larger schools of these fish have already triggered submarine alarms because they cast a […]

  • Rhinogobius shennongensis (2)

    8. December 2023

    The brook gobies (Rhinogobius) are as adult fishes pure freshwater inhabitants, which are found at most once in the brackish water of the lower reaches of running waters; but even this is the exception, not the rule. With 140 described species, 72 of which are generally considered valid, there is still a wide open field […]

  • Pseudocrenilabrus sp. Ruaha

    1. December 2023

    The small mouthbrooders of the genus Pseudocrenilabrus have been kept and bred in the aquarium since the beginning of modern aquaristics – in the 1880s. The species P. multicolor was once so popular that it was simply called “the mouthbrooder“, although it was already known at the time that there were hundreds of species of […]

  • Periophthalmodon septemradiatus

    29. November 2023

    Within the true mudskippers – these are the species that actively leave the water and search for food on land, etc. – there are two genera: Periophthalmus (19 species) and Periophthalmodon (3 species). They do not differ externally, only in the structure of their teeth. We have now received Periophthalmodon septemradiatus from India, a beautiful […]

  • Cichla kelberi “Spider”

    24. November 2023

    Just a few decades ago, the Peacock Basses from South America (genus: Cichla) were considered almost unsustainable for aquaria, but nowadays they are bred regularly and in large numbers. The latest craze is Cichla kelberi “Spider”, a breeding form whose origin is not yet known. The photos show our current stock, 16-18 cm long specimens, […]

  • Trichogaster trichopterus ( = Trichopodus t.)

    17. November 2023

    The spotted gourami is one of the most important ornamental fish of all and is one of the top 100 worldwide. The species is extremely widespread in Southeast Asia. Despite its relatively small size (usually 8-10, rarely up to 15 cm), this gourami is used as a food fish and can survive for a long […]

  • Dicrossus warzeli Bred

    10. November 2023

    The rarest of all checkerboard cichlids in the aquarium is Dicrossus warzeli, which was known as Dicrossus or Crenicara sp. Tapajós before its scientific description. In 1992 the very characteristically marked dwarf cichlid was discovered in an unnamed tributary (Igarapé) of the great Rio Tapajós in Brazil by the traveling aquarist Frank Warzel and brought […]

  • Elassoma evergladei

    6. November 2023

    The Pygmy Sunfish, Elassoma evergladei, is a classic dwarf fish and has been maintained and bred for many generations of aquarists. The species is best housed in a small species aquarium that does not require heating. The cute fish, growing only 2-3 cm, are completely peaceful, however the males defend an individual area against conspecifics. […]

  • Gobioides broussonnetii

    18. October 2023

    Only rarely we can offer the dragon fish, Gobioides broussonnetii, which actually is a species of goby. Now we received once again from Colombia this strange bottom dweller. The maximum length of the species is said to be about 40 cm. They are absolutely peaceful plankton eaters, which should be offered fine sandy substrate in […]

  • Macropodus opercularis: squeaky red!

    7. October 2023

    Solid red paradise fishes (Macropodus opercularis) have been known since the 1990s. However, they could not really establish themselves in the market, because the animals, which were also traded under the fancy name “Macropodus rex”, turned out to be very susceptible to diseases. Apparently the problem has been solved and we have now received really […]

  • Channa brunnea

    29. September 2023

    The Rainbow Snakehead (Channa bleheri) is without doubt one of the most beautiful and colorful snakeheads and with usually 12-15 cm total length (sometimes a bit more) it stays quite small. It originates from the north of India and belongs to the few Channa species without ventral fins. Since 2007 a very similar, also colorful […]

  • Laetacara curviceps

    25. September 2023

    Long before the Apistogramma species became popular, another dwarf cichlid from Brazil captured the hearts of aquarists: Laetacara curviceps, the Flag acara. At that time it was still called Aequidens curviceps. For some time it has unfortunately become quiet around him. Now we have once again received beautiful offspring of this small, peaceful and beautiful […]

  • Osphronemus laticlavius

    22. September 2023

    Once again we received the rare red-finned giant gourami (Osphronemus laticlavius). Like the common giant gourami this species grows around 60 cm long. The home of the fish is on Borneo, where it probably occurs naturally only in Sabah, i.e. in the very north of the island in the Malayan part. Since about 1985 this […]

  • Pelvicachromis pulcher wild yellow

    18. September 2023

    The yellow color variety of the species P. pulcher comes from southwestern Nigeria, where it is collected west of the Niger Delta in the Ethiop River area. The additional color designations yellow, red and green refer to the gill covers in P. pulcher, they all get red bellies.  In all Pelvicachromis, females are considerably more […]

  • Hephaestus habbemai

    4. September 2023

    New fish, new questions. This is how we could characterize our import of the grunter Hephaestus habbemai. These beautiful fish come to us from Indonesia and originate from the island of New Guinea. Originally (1910) they were described from the south of the island, from the Lorentz River. The species is a pure freshwater inhabitant; […]

  • Gymnogeophagus balzanii

    28. August 2023

    The hump of the male of G. balzanii is comparable to the feather tail of a peacock: it is simply the expression of manhood! The Paraguay Eartheater originates from the southern parts of South America and is imported now and then from Paraguay as wild collected stock, but the species is also bred on a […]

  • Datnioides campbelli

    25. August 2023

    Among lovers of large, predatory fish, the species of the genus Datnioides (formerly: Coius) enjoy great popularity. They are calm, expressive fish that, after a sometimes somewhat tough acclimation period in which they are shy and skittish, become very attached to the keeper and provide decades of enjoyment. All Datnioides species grow to 30-40 cm […]

  • Stiphodon atropurpureus

    25. August 2023

    The neon gobies of the genus Stiphodon are all beautiful fish. None of the 37 currently known species grows longer than 5-7 cm, usually they remain much smaller. Although adult Stiphodon live exclusively in pure freshwater, the larvae can only develop in the sea. Therefore, neon gobies live in streams near the coast. They spawn […]

  • Gymnochanda ploegi

    18. August 2023

    We have received this dwarf glass perch from Indonesia, which was named in honour of Alex Ploeg, who was in the passenger plane shot over the Ukraine on 17 July 2014. Gymnochanda ploegi is known so far only from West Kalimantan, the part of Borneo belonging to Indonesia. It is a pure freshwater species that […]

  • Wallaciia compressiceps (= Crenicichla c.).

    11. August 2023

    The dwarf spezies among the pike cichlids have recently been separated as an independent genus Wallaciia (see https://www.aquariumglaser.de/en/fish-archives/the-crenicichla-have-been-reclassified/). They include W. compressiceps, which occurs only in the Tocantins and Araguaia rivers in Brazil. It is one of the smallest, the prettiest and the most aggressive pike cichlid species. Although it only grows to a maximum […]

  • Apistogramma allpahuayo (2)

    7. August 2023

    From Peru a beautiful dwarf cichlid regularly comes to us, which is called “Apistogramma juruensis” on the exporter´s lists. The animals are very similar to A. cacatuoides and to A. juruensis, but can usually be easily distinguished from both by one coloration feature: a black chin spot, which was decisive for the common trade name […]

  • Heroina isonycterina

    4. August 2023

    It does not always have to be bright colors that make a fish interesting. Rather, it appeals to nature lovers to study the life history of the animals they keep and this often leaves a deeper impression in the long run than the colorful appearance. By cichlid standards Heroina isonyterina is a gray mouse. However, […]

  • Ptychochromis oligacanthus

    2. August 2023

    Of the cichlids endemic to Madagascar, Ptychochromis oligacanthus is also quite well known aquaristically by name. However, the understanding of what is meant by this species has changed thoroughly only a few years ago (2006). Previously it was believed that the species was widespread and divided into four different colored races. Today these races are […]

  • Dario dario

    28. July 2023

    The Dwarf Badis, also called Scarlet, has transformed itself from the highly paid sensation of the year 2000 to the always available classic in aquaristics. It originates from northern India (North Bengal), where it inhabits clear, moderately flowing waters with sandy bottoms and rich underwater plant growth at the foot of the Himalayas. In terms […]

  • Osphronemus goramy gold and albino

    24. July 2023

    Labyrinth fishes are among the most important ornamental fishes in the world. Their often bright colors and varied behavior make their care very rewarding. Most species also remain small, only very rarely exceeding the 10 centimeter mark. The exception are the giant gouramis (Osphronemus), of which there are four accepted species. They are not only […]

  • Brachygobius sabanus Vietnam

    19. July 2023

    From Vietnam we received this very nice bumble bee goby. The identification of bumble bee gobies is still in many cases a very tricky matter and often succeeds only with many question marks. Brachygobius sabanus was originally described from Borneo (Sabah), but our animals originate from Vietnam. However, the figure attached to the first description […]

  • Lentipes argenteus

    17. July 2023

    Once again we can announce a first import, but unfortunately a completely unspectacular one. Lentipes argenteus, a neon goby from West Sumatra, is – as they say – a dream in gray. We are quite sure that this will be our only import, because such fish are only interesting for specialists. For all of you […]

  • The Crenicichla have been reclassified

    14. July 2023

    With 93 accepted species, the pike cichlids (Crenicichla) are the most species-rich genus of cichlids anywhere. Closely related to Crenicichla are the Teleocichla cichlids. The relationship is so close that the independence of Teleocichla has been doubted several times. In a recent study in which 74 species of the complex could be considered (65 Crenicichla […]

  • Maylandia lombardoi

    10. July 2023

    Who remembers art class in school? Among the first things you learn are color temperatures, right? According to this, red, yellow and orange are warm colors, while blue, green and purple are cool colors. In Lake Malawi’s rock cichlids, the mbuna, the territory-owning males usually shine in cool colors (usually blue), and the females exhibit […]

  • Uaru fernandezyepezi

    7. July 2023

    In the Rio Atabapo in Venezuela, from which Uaru fernandezyepezi originates, it is already some weeks closed season, i.e. no fish may be caught there. The beautiful Uaru fernandezyepezi, which we can offer at the moment, are therefore the last specimens of the current season.  There was a time when people hardly dared to import […]

  • Pterophyllum Blue Angelfish 2023

    7. July 2023

    Solid blue-green angelfish are apparently the dream of many angelfish breeders. The body base color blue, a mutation, has been known in angelfish since World War 2, but it was very difficult to establish it in large-scale breeding. It was not until the end of the 1990s that this was achieved. Since then, a wide […]

  • Coptodon gutturosus

    23. June 2023

    Cichlids form new species comparatively quickly when placed in geographic isolation. For them, the speciation process often takes only a few decades or centuries, whereas other groups often need millennia. Lake Bermin in Cameroon is a comparatively tiny crater lake with a surface area of only 0.6-0.7 km2. The lake is located in a former […]

  • Chromidotilapia kingsleyae

    23. June 2023

    The wonderful West African cichlids have been somewhat forgotten in recent decades. In the 1970s and 1980s, on the other hand, they experienced a real boom and a great many new species were discovered at that time because ornamental fish collectors were only too happy to fulfill the aquarists’ desire for previously unseen cichlids. Many […]

  • Placidochromis milomo

    21. June 2023

    Lake Malawi in the heart of Africa is home to an enormous variety of cichlids. Often it is difficult to decide whether in individual cases they are different species or local variants. Extremely popular in aquaristics are the rock cichlids (Mbuna). But also among the non-Mbuna, which in their habitat are not so dependent on […]

  • Bostrychus zonatus

    16. June 2023

    Bostrychus zonatus is a sleeper goby and becomes about 15 cm long. They are predatory fish, which should therefore only be kept together with species that have at least half the body length of the gobies, larger is safer. The beautiful animal is widespread in fresh and brackish water in New Guinea and northern Australia. […]

  • Butis gymnopomus

    16. June 2023

    Sleeper gobies the genus Butis (there are 6 recognized species) belong to the most original members of their kind. They swim around in the aquarium in every imaginable posture, especially often with the belly up, but also upside down or with the snout up. Thereby they imitate a floating piece of wood and are not […]

  • Parasphaerichthys ocellatus

    12. June 2023

    This extremely rarely imported species originates from Burma. The charming fish attains a length of only 2-3 cm. The species is a close relative of the mouthbrooding chocolate gouramis, but P. ocellatus is a bubblenest builder although the eggs look like the eggs of mouthbrooders. In the habitats of P. ocellatus appear heavy day-night changes […]

  • Apistogramma kullanderi

    7. June 2023

    The “Giant Apistogramma” caused a flurry of excitement when it was discovered in 2009 during an expedition to the Serra do Cachimbo (Pará, Brazil). The discoverers, J. L. O. Birindelli and M. Sabaj Perez, reported on this great fish in various journals, initially under the name A. sp. “Gigas”. Then in 2014, Varella and Sabaj […]

  • Microctenopoma fasciolatum

    2. June 2023

    Unfortunately imports from the Congo are only rarely possible. But now it was once again so far and among other species we have received nice wild catches of the Banded ctenopoma (Microctenopoma fasciolatum, formerly Ctenopoma f.). The currently imported form – the exact locality is unknown to us – differs quite clearly in color from […]

  • Sineleotris saccharae

    19. May 2023

    From the Hong Kong area comes this beautiful, but also delicate goby. The maximum length of the species is about 10 cm. The basic temperature requirements are well known from the White Clouds (Tanichthys albonubes), which occurs in the same region: 16-22°C for normal care, somewhat higher for breeding, short-term up to 28°C are tolerated. […]

  • Helostoma temmickii

    17. May 2023

    The kissing gourami (Helostoma temmickii) in its pink breeding form is one of the best known labyrinth fish. It is not actually bred as an ornamental fish, but as a food fish. The species grows up to 30 cm long under suitable (fattening) conditions and is considered delicate. In the nutrient-rich, turbid breeding ponds, the […]

  • Crenicichla zebrina

    12. May 2023

    Crenicichla zebrina is one of the still extremely high-priced fishes, because the finding areas are located far away and it is very costly to transport live fishes healthy and lively from there to the export stations. The wonderful coloration makes the animals nevertheless desirable.

    Unfortunately it is hard to tell the sexes of C. zebrina apart and furthermore randomly mated animals rarely get along. Juveniles, on the other hand, are inconspicuous in coloration and still expensive, but quite peaceful among themselves. A troop of young animals is the best chance to get to a breeding pair. 

    At the moment we can offer once again adult animals (for pictures see https://www.aquariumglaser.de/en/fish-archives/first_import_crenicichla_zebrina_arrived_en/ and https://www.aquariumglaser.de/en/fish-archives/crenicichla_zebrina_en-2/ and also youngsters (actual photos in this post and https://www.aquariumglaser.de/en/fish-archives/crenicichla_zebrina_en/).

    For our customers: the animals have code 674051 (5-8 cm) and 674058 (24-28 cm) on our stocklist. Please note that we only supply wholesale.

  • Rubricatochromis “lifalili” (formerly: Hemichromis)

    26. April 2023

    There is no doubt about it: the Red Jewel Cichlids, formerly called Hemichromis bimaculatus, are among the most popular aquarium fishes. For several generations of mankind they have been swimming in the aquariums of the world and find again and again new, enthusiastic followers – however also aquarists who swear an oath: never again Red […]

  • Heterotilapia buettikoferi (formerly: Tilapia b.).

    12. April 2023

    The large cichlids of South and Central America have a firm place in aquaristics. However, aquarists have a mental problem with the no less magnificent large cichlids of Africa. When the name “tilapia” is mentioned in a fish discussion, everyone immediately thinks of gray underwater lawnmowers with carp format. There is a grain of truth […]

  • Symphysodon discus “BLUE MOON”.

    6. April 2023

    The Real or Heckel Discus (Symphysodon discus) is always somewhat behind its close relatives, the Blue and Green Discus, in popularity. This is certainly only because it breeds less willingly. There is no doubt about its special beauty. The Heckel Discus “Blue Moon” is found only in a rather remote region of the Alto Nhamunda […]

  • Apistogramma psammophila

    31. March 2023

    The two-banded dwarf cichlid, Apistogramma diplotaenia, is one of the dream fish of many Apistogramma lovers. The species originates from the Rio Negro drainage in Brazil. Unfortunately, this fish is also one of the most demanding species of the genus and even minor carelessness – e.g. a missed water change and the resulting increase in […]

  • Thorichthys aureus

    31. March 2023

    The “golden cichlid” is one of the first cichlid species that became known for aquaristics. It originates from Mexico. Already in 1911 the first imports took place. However, the species never really caught on in general, in contrast to its cousin T. meeki, which was first imported more than 20 years later and is still […]

  • Ptychochromis insolitus

    29. March 2023

    One of the rarest animals in the world is this Madagascar cichlid, which was only scientifically described in 2006 and already in 2013 it was feared to be extinct. It existed in only one river on Madagascar, the Mangarahara, after which the perch is also called Mangarahara cichlid. A dam project and excessive water extraction […]

  • Enigmatochromis lucanusi

    24. March 2023

    After many years we received again this beautiful pastel colored dwarf cichlid from Guinea. Only in 2009 the species, which belongs to a group of species popularly also called king cichlids, was scientifically determined, before it was known in the hobby as “Pevicachromis sp. aff. roloffi Blue Fin”. The females of this species show – […]

  • Rhinogobius shennongensis

    17. March 2023

    The brook gobies (Rhinogobius) are as adult fishes pure freshwater inhabitants, which are found at most once in the brackish water of the lower reaches of running waters; but even this is the exception, not the rule. With 140 described species, 72 of which are generally considered valid, there is still a wide open field here for aquarists with an urge to explore. All species can be maintained well in the aquarium. When breeding, there are those Rhinogobius that have tiny larvae that grow in the sea and those that have large larvae that grow in freshwater. All species are cave spawners, the male guards the clutch until the larvae hatch. Brood care ends when the larvae swim free.

    For the first time we could import Rhinogobius shennongensis from China. It originates from the Yangriwan, upper Hanjiang River, Mount Shennnong, Hubei Province. The maximum length is about 5-6 cm, males are larger than females. The sexes are most easily distinguished by the shape of the head. According to their origin, the fish are kept not too warm (18-24°C), in clear, oxygen-rich water with a good current. They are bottom fish, the males form territories. Rhinogobius shennongensis is somewhat quarrelsome; therefore possible tank mates should not be too squeamish. All common ornamental fish food is eaten, although some specimens do not like dry food. Frozen food is always accepted.

    For our customers: the fish have code 453480 on our stocklist. Please note that we only supply wholesale.

  • Rhinogobius sp. “Davidi”

    17. March 2023

    We have the great ambition to open up new species for aquaristics again and again. Therefore it is not excluded that we also import species whose scientifically exact determination is not successful, because simply not enough scientific research has been done about the animals so far. The extremely species-rich genus Rhinogobius is a good example […]

  • Scalare leopoldi Red Spots Peru

    27. February 2023

    From Peru we received wonderful, large angels (Pterophyllum). They have a yellowish to reddish back and many brown-red spots on the flanks. This exceptionally beautiful wild form has been called Pterophyllum leopoldi for decades due to a misidentification in aquarium circles. The “true” P. leopoldi originates from Brazil and is the fish always referred to in the hobby as P. dumerilii, while the “true” P. dumerilii from Brazil is considered synonymous with P. scalare. Other names, equally incorrect, that circulate for Peru scalars are “Peru Altum” or “Pterophyllum peruensis”.

    In fact, the “Red Spots Peru” is a scientifically undescribed species. This has nothing to do with the red spots: this species also exists without red spots. Rather it is the black, comma-shaped spot, which extends as extension of the 2nd body bandage into the dorsal fin, which is characteristic for the species (in the order: eye bandage – 1st body bandage – 2nd body bandage – tail root bandage, thus four dark vertical bands, of which the tail root bandage is often only indistinctly visible).

    Regardless of the name, the red-spotted angelfish from Peru are magnificent animals, which unfortunately can be imported only very rarely and in small numbers. 

    For our customers: the animals have code 699307 on our stocklist. Please note that we only supply wholesale. Only available in limited numbers!

  • Vieja breidohri

    24. February 2023

    The 1980s and 1990s were the high times of traveling aquarists who wanted to shed light on Central American cichlids. And this succeeded more than satisfactorily! One of these amateur researchers in the best sense of the word was Hans-Günther Breidohr (1938-2017). In his honor Uwe Werner and Rainer Stawikowski named a cichlid Paratheraps breidohri, […]

  • Cryptoheros myrnae “Rio Sarapiqui”.

    24. February 2023

    Central American cichlids often require large aquariums. Not so much because of their swimming needs, but because they form territories and are often unbearably aggressive in aquariums that are too small. In large aquariums, on the other hand, this is hardly a problem. But there are also dwarf cichlids among the Central Americans, which – […]

  • Betta splendens – real fighter Pla Kat Luk Maw

    22. February 2023

    It is a well known fact that the Betta splendens kept in the aquarium hobby as ornamental fish do not represent the species as it appears in the wild, but a domesticated fish. Initially this sport has been bred for combats, similar like sports of cocks and dogs. Only in the 1920ies, when supplying ornamental […]

  • Betta strohi

    10. February 2023

    The species status of Betta strohi is controversial. It is a form from the species complex around Betta foerschi (see https://www.aquariumglaser.de/en/fish-archives/betta-foerschi-bred/). Some authors consider B. strohi to be a synonym of B. foerschi, others a valid species. “Technically” the two differ by a rather inconspicuous feature, namely the eye line. In Betta strohi the line […]

  • Scatophagus argus

    3. February 2023

    The Scat is one of the fish species known to science almost from the beginning of scientific naming. Scatophagus argus was already described in 1766. This first description refers to a red scat. The name “rubifrons” for red scats that is always bandied about in the hobby is a purely fanciful name with no scientific […]

  • Glossamia aprion

    3. February 2023

    The cardinalfishes (Apogonidae) are a species-rich (ca. 370 species), mainly marine group of mostly small-bodied, mouth-breeding perch-like fish. Very well known species are the Kauderni or Banggai Cardinalfish (Pterapogon kauderni) or the Pyjama Cardinalfish (Sphaeramia nematoptera), several other species belong to the standard assortment of marine aquaristics. Only very few species have made it into […]

  • Apistogramma sp. Amaya

    27. January 2023

    New catch areas bring immediately new species! That these are also wonderfully colored animals, as in the case of the bright red Nannostomus or the Apistogramma sp. Amaya (also called A. sp. Cenepa II) presented here, is surprising. Because Peru is really well collected! But let’s not be surprised, but enjoy the beautiful new imports! […]

  • Labidochromis sp. “Mbamba”

    23. January 2023

    At first sight one could think Labidochromis sp. “Mbamba” (the species is not yet scientifically described) is a typical mbuna of Lake Malawi: blue ground color, zebra stripes. But in reality Labidochromis sp. “Mbamba” is quite different. It is not a mbuna in the real sense, which are known to be algae/Aufwuchs eaters and aggressively […]

  • Symphysodon aequifasciatus “Royal Green Tefé”.

    20. January 2023

    The kings of the discus fishes are the “Royal” varieties. A discus is called Royal if green or blue pattern elements are spread over the entire body surface.  Among the green discus the Royal from Tefé in Brazil (which is also one of the type localities of S. aequifasciatus, i.e. the locality from which the […]

  • Lamprologus brevis

    16. January 2023

    Snail cichlids are fascinating animals. They have chosen empty snail shells – in Lake Tanganyika there are large accumulations of empty shells of snails of the genus Neothauma – as their center of life. Neothauma snails are with a diameter of 4-5 cm relatively large snails from the relationship of the mystery snails. However, in […]

  • Rubricatochromis: a new genus name for the red jewel cichlids

    23. December 2022

    Red jewel cichlids are among the most popular aquarium fishes of all. For over 100 years, they have delighted aquarists around the world with their blaze of color and wonderful breeding habits. There is disagreement about the number of species, because these fish are very variable. Until now the red jewel cichlids were known under […]

  • Datnioides polota

    16. December 2022

    From India (Orissa) we have received quite adorable tiger perch babies of the species Datnioides polota. Most of the only 1-2 cm long babies still have the dark baby dress, which is only interrupted in the front third of the body by a bright band. But single animals change already into the adult dress, which […]

  • Channa marulius

    12. December 2022

    Which species is the largest snakehead fish? Unfortunately, this question cannot be answered unambiguously, because the expression “angler’s lingo” has already become proverbial for uncertain statements. Anglers (and not only them!) like to exaggerate a little. But indisputable is: Channa marulius from India belongs to the top candidates for the race. The largest documented catch […]

  • Chlamydogobius eremius 

    8. December 2022

    The desert goby (Chlamydogobius eremius) is a wonder of nature in terms of temperature adaptability. Originally it comes from the desert of South Australia. There it can be very hot during the day, but very cold at night. The high heat capacity of the water prevents the fish from having to endure sudden temperature changes, […]

  • Symphysodon wild Nanay Green

    5. December 2022

    The Rio Nanay is a large, left-bank tributary of the upper Amazon River. It is considered a blackwater river. The Rio Nanay is home to Green Discus, which have always been sought after in the hobby. In the past, in the 1950s and 1960s, these precious animals came to us via the Colombian city of […]

  • Geophagus steindachneri

    2. December 2022

    The redhump eartheater (Geophagus steindachneri) from Colombia has had a regular place in the aquarium since it was first imported to Germany in 1972. There are numerous reasons for this. First of all it is very attractively colored. The males develop a red colored forehead hump, which varies very much in size. Over all: the size. In fact, G. steindachneri can grow up to 25 cm long! But sexual maturity starts already with 6 -7 cm length. 

    Geophagus steindachneri is considered to be the most specialized mouthbrooder of South America, because the eggs are taken into the maternal mouth immediately after spawning. Instead of egg spots in the anal fin, as found in many African mouthbrooding cichlids, G. steindachneri have orange spots in the corners of the mouth, which achieved the same effect.

    We have at the moment nice offsprings of the species in the stock, where the males have as a special feature green-golden areas in the area of the gill covers.

    For our customers: the animals have code 678212 on our stocklist. Please note that we supply exclusively to wholesalers.

  • Blue Dempsey Cichlids

    25. November 2022

    The Blue Dempsey is a beautiful blue variant of the normally rather dark colored Rocio octofasciata (formerly: Cichlasoma or Nandopsis octofasciatum). In the youth Blue Dempsey still have relatively many black color parts, the extremely intensive, then almost solid blue coloration develops only with increasing age.  Presumably the animals are descendants of a mutant, which […]

  • Biotodoma cupido Peru

    11. November 2022

    The small cichlid Biotodoma cupido – it reaches about 12-15 cm total length, but is already sexually mature at 6-8 cm – is probably the most widespread cichlid species in Amazonia. Among experts there is cheerful disagreement whether all the different looking animals are only local color variants or independent species. Be that as it […]

  • Badis pallidus

    9. November 2022

    The flood of newly discovered Badis species does not stop. It is astonishing that 23 new species of these fishes have been scientifically accepted in the last 20 years and only four in the 200 years before! Badis pallidus was only described in 2019; it belongs to the immediate relationship of Badis badis and cannot […]

  • Channa aurantimaculata WILD

    7. November 2022

    We have the probably most beautiful of all snakeheads once again available in limited numbers. This species grows up to 50 cm long in the aquarium, but normally they reach only 20-25 cm in the wild; our currently stocked fish are 14-18 cm long. The species is endemic (i.e. only found there) in northern India. […]

  • Apistogramma panduro

    28. October 2022

    In Apistogramma panduro from Peru (drainage of the Rio Ucayali, east of Jenaro Herrera) the females are absolutely emaciated. They are at least as beautiful as the males, if not more so; they fight as if they were males, and they show marked polychromatism. Polychromatism, or multicolorism, is when animals are individually, not species-specifically, differently […]

  • Rocio octofasciata

    28. October 2022

    The beautiful cichlid Rocio octofasciata from Mexico is still known by many older people as Cichlasoma biocellatum. But all over the world young and old know him also under the popular name “Jack Dempsey”, although you have to be quite old to have experienced this legendary heavyweight boxer still in his active time: Jack Dempsey’s […]
