10b. Catfishes: Suckermouths, Plecos and L-numbers (304)

  • Rineloricaria eigenmanni

    13. June 2024

    There is no consensus among ichthyologists (= fish experts) as to the correct generic name for the whiptail catfish of the narrower Rineloricaria relationship. Some group all species together as Rineloricaria, others divide these fish into Rineloricaria and Hemiloricaria. Rineloricaria in the broadest sense is very species-rich, currently 64 species are recognized and there are […]

  • Hypancistrus inspector “L102, Snowball Pleco”

    7. June 2024

    L102 is one of the plecos that has long been known in the hobby and was given its L number back in 1992. These animals originated from the lower Rio Negro in Brazil and were soon given the popular name “Snowball Pleco” because of the large white spots on a black background. The species was […]

  • Rineloricaria cf. sanga

    7. May 2024

    We received Rineloricaria from the Brazil-Uruguay border region. The genus Rineloricaria is extremely species-rich with currently 72 accepted species and new species are constantly being added. Unfortunately, there is no complete overview of the genus, making identification extremely difficult. The southern Rineloricaria are also particularly tricky because only a few live observations have been made […]

  • Panque suttonorum ( = P. suttoni)

    7. May 2024

    In the 1980s, the blue-eyed Panque was one of the most common loricariid catfishes on the market. Incidentally, the correct name is Panaque suttonorum. For unknown reasons, the animals are hardly available nowadays. There are a lot of rumors that an environmental disaster is to blame or that a madman has poisoned the river or […]

  • Pseudorinelepis sp. L95a

    22. March 2024

    At present, only one species of Pseudorinelepis is recognized by scientists, namely P. genibarbis. According to this assumption, the species is widely distributed in tropical South America and occurs in the Amazon and its tributaries as well as in the Orinoco and its catchment system. According to this theory, the color differences observed in living […]

  • Ancistrus sp. LDA45 / L349

    22. March 2024

    Hardly any other genus of loricariid catfish, often referred to as L-catfish, is as widespread and important in aquariums as Ancistrus. Practically every aquarium is home to a few of these problem-free animals, which do an excellent job of cleaning the glass, look bizarre and hardly disturb other fish. But when it comes to identification […]

  • Panaque from Colombia: L190, L191, L330

    15. March 2024

    We can currently offer all three striped Panaque from Colombia, namely L330 Panaque nigrolineatus laurafabianae (Colombia: upper Rio Guaviare drainage), L190 Panaque nigrolineatus nigrolineatus (Colombia/Venezuela: Rio Meta and lower drainage of the Rio Guaviare) and L191 Panaque cf. titan (Colombia: Rio Caguán, drainage of the Rio Caqueta). We have comparable sizes of all three forms […]

  • Rineloricaria sp. Jacareacanga

    28. February 2024

    We have received a small number of these new, really unusually marked Rineloricaria sp. Jacareacanga – named after the place where they were found on the Rio Tapajós. Many thanks to Ingo Seidel for the information on the origin of these catfish! Our largest animals are about 15 cm long. They are real beauties, who […]

  • Planiloricaria cryptodon

    24. January 2024

    Currently we have wonderful flounder whiptail catfish from Peru in stock. They are currently 10-13 cm long. These sizes give only the body length, as in Planiloricaria there is a filament on the upper lobe of the caudal fin that is as long as the body! Maximum length given in literature is 35 cm. Nevertheless, […]

  • Pseudancistrus genisetiger

    15. December 2023

    This beautiful loricariid catfish was already scientifically described in 1941. The type locality is the drainage of the Rio Jaguaribe in the Brazilian state of Ceará in the north-east of the country. The maximum length published to date is around 13 cm (10 cm without caudal fin). The Rio Jaguaribe is notorious for its erratic […]

  • Spatuloricaria sp. „Black-White Peru“

    8. December 2023

    The genus Spatuloricaria comprises currently 11 accepted species. Members of this genus are large, splendid whiptail cats. There is probably no species that stays smaller than 30 cm in length, some become definitely larger. This means that the fish have to be kept in large aquaria. Spatuloricaria are sensitive against poor water quality. Thus a […]

  • L90a Panaque bathyphilus

    6. December 2023

    The large, wood-eating Panaque species have their loyal fans. Although these animals only reach us in relatively small numbers, they have been on offer from exporters for decades. This includes L90, the variably colored Panaque bathyphilus from Peru, which can easily reach a body length of 60 cm in old age. We have reported on […]

  • Scobinancistrus raonii L82 ( = “Scobinancistrus sp. Orange Spot”)

    3. November 2023

    The beautiful L82 originates from the lower Rio Xingu in Brazil (around Altamira). The species is very variable in terms of spot size and shape. Wild-caught specimens also often have a yellowish-orange spot coloration or shiny green-blue spots (“Opal-Pleco”). A few days ago (on October 30, 2023), the species, which received its L-number back in […]

  • Rineloricaria lanceolata “Albino“

    31. October 2023

    Albinism, i.e. the complete or partial absence of black color pigments in the body cells, occurs widely as a mutation in the animal kingdom. While albinos rarely survive in the wild because of their striking light color, they are particularly popular in commonly bred animals. On many people albinos seem very attractive. The species Rineloricaria […]

  • Squaliforma cf. emarginata L11

    11. October 2023

    Among the loricariid catfishes that are known by scientists for a very long time already is this species. It has been described initially 1840 under the name of Hypostomus emarginatus. Since then it has been placed in different genera, in 2001 in Squaliforma and in 2016 in Aphanotorulus, when Squaliforma has been considered to be […]

  • Chaetostoma dorsale (L147, L443)

    2. October 2023

    The bristlemouth catfish (Chaetostoma) are an exceptionally diverse genus of suckermouth armored catfishes. According to Fishbase (2023), 47 species are currently considered valid. From Colombia, more precisely from the surroundings of the city of Villavicencio, the capital of the department of Meta, Chaetostoma have been exported for decades as common “bread-and-butter fish”. However, it was […]

  • Peckoltia sp. L265/LDA84

    15. September 2023

    There are three forms of orange fringed plecos among L catfishes, namely L76 (tributaries of Rio do Pará, Brazil), L99 (also tributaries of Rio do Pará, Brazil), and L265 (Rio Tajajós and its tributary Rio Jamanxin, Brazil). Thus, all sites are located within the state of Pará. L265 has also received LDA number 84 after […]

  • Baryancistrus xanthellus L81c Sao Felix

    21. July 2023

    The great hype surrounding L catfish has long since given way to normal handling of these beautiful and interesting fish. One of the enduringly popular species is Baryancistrus xanthellus, which entered the hobby under L numbers L18, L81 and L177. The species is common and frequent in the Rio Xingu and its tributaries. Nevertheless, it […]

  • Ancistrus sp. L 267 Pozuzo

    2. June 2023

    The “four-striped Ancistrus” L267 is still a somewhat mysterious species. Even if the first specimen became known already in 1996, this Ancistrus always remained a top rarity in the trade and was not available at all for years. Even the origin remained unknown until now. We get the fish from an exporter in Peru, who […]

  • Pseudolithoxus nicoi

    21. April 2023

    We could import some specimens of the pretty white fringed flying catfish Pseudolithoxus nicoi from Venezuela. This very rarely available species grows to a length of about 12 cm. P. nicoi originates from the Rio Casiquiare, which connects the Rio Negro with the Orinoco. There is great similarity to P. anthrax (L235), which is why […]

  • Loricaria luciae

    31. March 2023

    From Paraguay we received a nice shipment of mouthbrooding whiptail catfishes (Loricaria). Because of the known difficulties to identify species in Loricaria exactly, we first named them provisionally as L. simillima, the aquaristic best known species of the genus, which also occurs in Paraguay. Now that the animals are somewhat acclimated and also the latest […]

  • Lamontichthys filamentosus

    24. March 2023

    From Peru we could import some Lamontichthys filamentosus. This graceful, beautiful species reaches a body length of about 20 cm, the fin filaments can become even that long.  Lamontichthys are very sensitive fish, which need optimal water conditions. In addition, the fish are often difficult to bring to the food. Obviously they are very shy […]

  • Panaque sp. L191

    27. January 2023

    The large wood-eating Panaque of the relationship around P. nigrolineatus are fantastic fishes. Juveniles are almost splendidly colored, so also L191, a species which is still not described scientifically. L191 originates from Colombia. According to the available information the native area is the Rio Caguán in Caquetá. Particularly splendid is with young L191 the green […]

  • Sturisomatichthys sp. Colombia II

    20. January 2023

    The whiptail catfishes belong to the popular and well breedable loricariids. For example, the Real Royal Farlowella (Sturisomatichthys festivus) has been in continuous breeding for almost 50 years, wild catches of this species are very rare. For other species, wild catches and offspring coexist in the hobby.  In former times Sturisomatichthys was considered to mainly […]

  • Soon available: Rineloricaria aurata

    13. January 2023

    From Paraguay we regularly receive shipments of the small whiptail catfishes of the genus Rineloricaria. No less than 65 species are currently recognized, which makes identification in many cases almost impossible without knowledge of the origin. But in the case of Paraguay, there is a recent revision of the species known from this river system […]

  • Ancistomus cf. sabaji L75 offspring

    6. January 2023

    We have received very nice offsprings of L75, which are currently 6-8 cm (26480-L 075x-2) and 10-12 cm (26480-L 075x-4) long. Here the report of the breeder, for which we thank very much:

    Breeding report Ancistomus cf. sabaji L75

    Until breeding L75 was a long way. I tried it for seven years with two groups. It turned out: patience is always the key to success with difficult plecos.

    L75 is a pleco that has fascinated me for some time, so I was happy when I got three adults (two males and one female) in 2014. I had no success with this group, but six years later, in 2020, I bought seven more. Things went very quickly with this group. Several of the males showed interest in the caves, and I was happy to soon find one on a large clutch. The fight for the cave with other males stressed the brooding animal quite a bit, and after 3 days he threw the clutch out of the cave. 

    I managed to recover about fifty eggs, but because of a fungus, only six hatched, all of which fortunately survived. Later I removed four adults, so I ended up with the breeding male and two presumed females. Further reproduction now went very well, with the male mating with both females and taking care of the eggs and young, this time without disturbance.

    The adults are 20-25 cm and are fed an insect-based diet with some fresh fish and mussels. Soft, neutral water, 28-30 degrees Celsius. The number of eggs per clutch was 150-250, depending on the size of the female. The fry grow very well on a varied diet under the same conditions, are gray at first and get the leopard pattern at about 3 cm. All in all, due to its more active behavior compared to other plecos, L75 is a very entertaining species whose care and breeding can only be recommended.

  • Parotocinclus bahiensis and P. cearensis

    6. January 2023

    The genus Parotocinclus currently exists in a kind of shadowy existence in aquaristics. In contrast to their cousins of the genus Otocinclus, hardly anyone knows these equally small loricariids, which are, however, equally zealous algae exterminators. We have received from the Northeast region (Região Nordeste), more precisely from the states of Cereá and Bahia of […]

  • Ancistrus sp. Bushmouth LDA 72

    9. December 2022

    Ancistrus species belonged to aquaristics long before one even thought of the term L or LDA number. Unfortunately, the systematics of the group is complex, there have been and still are misidentifications and – this is especially unfortunate – the species can apparently often be crossed, so that aquarium hybrids have been created unintentionally. Such […]

  • Pseudacanthicus sp. L600

    4. November 2022

    We have received fantastic leopard cactus plecos L600. They are german bred ones. One specimen is as beautiful and flawless as the other! We are extremely enthusiastic about the quality of the animals. They are currently 6-8 cm long. For our customers: the fish have code 26480-L 600-2 on our stocklist. Please note that we […]

  • Parancistrus sp. Rio Araguaia L56n / LDA46

    2. November 2022

    The genus Parancistrus includes only two scientifically accepted species, the Golden Parancistrus (P. aurantiacus), which was erroneously also assigned L-number 56 (this is incorrect) and P. nudiventris, which was assigned L-numbers 31 and 176; this is a black catfish with very fine white spots. In addition, we know L258 from Rio Iriri, a black catfish […]

  • Hypostomus sertanejo

    26. October 2022

    For the first time we can offer this very nice Hypostomus from the Rio Jaguaribe (Cerea State, Brazil). It is a species that was described scientifically only in 2017, although 19 specimens of this species were found in the scientific collection of the Academy of Natural Sciences of Philadelphia, U.S.A., which had been collected and […]

  • Rineloricaria teffeana

    24. September 2022

    The small remaining whiptail catfishes of the genus Rineloricaria enjoy great popularity among aquarists. They have a whimsical appearance, are peaceful, have no high space requirements and can usually be bred quite well. Some species have even really fancy pattern. The most beautiful is certainly R. teffeana. It has no bright colors, but a really […]

  • Parotocinclus jumbo LDA25, now available as German bred!

    24. September 2022

    The cute Parotocinclus jumbo, also known as Pitbull Pleco or LDA25, is a very popular aquarium fish. Unfortunately imports take place only very irregularly and can hardly be planned. Therefore we are happy to be able to offer this nice little fish as offspring now. More information about the species can be found here: https://www.aquariumglaser.de/en/fish-archives/lda25-parotocinclus-jumbo-2/ […]

  • L90a Panaque bathyphilus

    8. July 2022

    The large-growing, magnificent Panaque bathyphilus is very variable in coloration. We have at present quite splendid 16-20 cm long animals in stock. With this they are about half grown, as maximum length for P. bathyphilus about 60 cm are given. It goes without saying that these large fish should only be kept in large aquariums. […]

  • Glyptoperichthys parnaibae

    25. May 2022

    For the first time ever we can offer Glyptoperichthys parnaibae, so far known exclusively from the Rio Parnaiba in Brazil. The Rio Parnaiba is located in the northeast of Brazil and has a high proportion of endemic, i.e. only there occurring fish species, because there is no connection to other river systems. The juveniles of […]

  • L129 var Hypancistrus debilittera

    16. May 2022

    The small remaining, nicely marked Hypancistrus debilittera from the Rio Bita (a tributary to the Rio Meta, Colombia, Orinoco drainage) enjoys a great popularity since years. Already with 7 cm length the males become sexually active, the maximum length is given with about 12 cm. We import this species regularly. Recently we received a “Hypancistrus […]

  • Acanthicus adonis

    6. May 2022

    Now it is season again for one of the most beautiful of all loricariid catfishes: Acanthicus adonis. The species name “adonis”, which is reminiscent of the ancient god of beauty and vegetation, Adonis, is aptly chosen. For like the god described as a beautiful youth, the Adonis catfish is such a beauty only when young. […]

  • Rhinelepis cf. strigosa

    14. April 2022

    The two species of the genus Rhinelepis – R. aspera and R. strigosa – belong with over 60 cm attainable final size to the largest armored catfishes at all and are therefore predestined as show objects in zoos, public aquariums and of course also for owners of gigantic private aquariums. Color-wise they have nothing to […]

  • L92/L194 Lasiancistrus tentaculatus

    7. April 2022

    There seems to be a consensus among armored catfish enthusiasts that L92, which is very widespread in the Orinoco drainage of Colombia and Venezuela and later received another L-number, namely L194, is identical to Lasiancistrus tentaculatus, which was described in 2005. However, L. tentaculatus is described as more or less monochromatic brown, while L92 is […]

  • Hypoptopoma sp. Ucayali

    4. April 2022

    From Peru we could import very nice Hypoptopoma. Most of the import consisted of H. gulare (see https://www.aquariumglaser.de/fischarchiv/hypoptopoma-gulare/), but there were some specimens with very conspicuous, broad bands in the dorsal fin and contrasting caudal fins. Unfortunately the identification attempt based on the current revision of the genus (Aquino & Schaefer, 2010) did not give […]

  • Ancistrus sp. L184 (= L107)

    18. March 2022

    One of the most attractive Ancistrus species is this so far not scientifically identified species from the middle Rio Negro in Brazil. There the beautiful fish is not rare, in some places even very common, but the species apparently prefers biotopes which are avoided by the local fishermen; otherwise it can hardly be explained why […]

  • Rineloricaria lanceolata “Red Dun“

    11. March 2022

    For the first time we can offer the breeding form “Red Dun” of the Chocolate Whiptail Catfish. This new breeding form goes back to a wild-caught male that we were able to import from Paraguay in November 2015 (see https://www.aquariumglaser.de/en/fish-archives/rineloricaria_lanceolata_en/). We gave it, together with some normal females of the same import, to our breeder […]

  • Hypancistrus contradens L201a Big Spots

    4. March 2022

    From the lower Rio Ventuari in Venezuela – the largest tributary of the Orinoco – as well as from the Orinoco itself in the Ventuari estuary comes a beautiful Hypancistrus. It has large, bright spots on a deep black ground. The coloration of the spots is varying between shy white and orange-pink. There is a […]

  • L501 Hypanacistrus sp. Mitu

    25. February 2022

    Snowball plecos belong to the largest Hypancistrus species. They can reach up to 20 cm in length. Members of the group are easily recognized by the conspicuous black fringes in the dorsal and caudal fins.  Distinguishing the aquaristically known form, on the other hand, is tricky and sometimes simply impossible without knowledge of the origin. […]

  • Pseudacanthicus sp. L185 Bred

    18. February 2022

    The cactus plecos (Pseudacanthicus) are popular with owners of large aquariums. L185 originates from the Rio Xingu and is also called Belo Monte Cactus Pleco, because this catfish used to be caught there. We do not know if the species still exists there, or if it was wiped out by the construction of the Belo […]

  • Acestridium dichromum

    24. January 2022

    The strange sucking catfishes of the genus Acestridium – there are currently seven recognized species in the genus – could also be called “dwarf needle catfishes”, because they look like a miniature version of the needle catfishes of the genus Farlowella. Unfortunately, these animals are still an aquaristic challenge, which only very experienced aquarists should […]

  • The sturgeon catfishes of Paraguay: Sturisoma barbatum or S. robustum?

    14. January 2022

    From Paraguay wonderful, partly very large sturgeon catfishes (Sturisoma) are imported. Two Sturisoma species are known from the Rio Paraguay: S. barbatum, described already in 1853 by Kner, and S. robustum, described in 1904 by Regan. The two species differ from each other only insignificantly.  The most important anatomical feature distinguishing the two species is […]

  • Baryancistrus sp. Snowflake LDA 33 / L142

    7. January 2022

    This beautiful loricariid catfish comes from the Rio Tapajós in Brazil. Usually, 4-5 cm long youngsters are imported from these catfishes, which look very attractive with their large, white dots on a deep black ground and fully deserve the name “Snowball-Pleco”. In addition to high water temperatures (not below 28°C), these catfishes should be kept […]

  • Glyptoperichthys gibbiceps

    29. November 2021

    The red highfin sucker is a classic, which found its lovers long before the invention of the L-numbers. Juveniles are really adorable and excellent algae killers. In addition they look very beautiful. Since this catfish easily grows to 30-40 cm in length, there are two camps among aquarists. Some are critical of the animal because […]

  • Rineloricaria parva

    25. November 2021

    From Paraguay we regularly receive shipments of the small whiptail catfishes of the genus Rineloricaria. No less than 65 species are currently recognized, which makes identification in many cases almost impossible without knowledge of their origin. But in the case of Paraguay, there is a recent revision of the species known from this river system […]

  • Ancistrus Orange Brown “LDA16”

    22. November 2021

    This extremely attractive Ancistrus is a breeding form. The actual LDA 16 is a wild form imported in 1994 from Brazil (Rio Puraqequara, a tributary of the Rio Guamá, which in turn is a tributary of the Rio Tocantins) and is uniformly purple-brown in color. We do not know if the orange-blotched Ancistrus descended from […]

  • Hypostomus roseopunctatus L311

    19. November 2021

    Not less than 148 species are counted to the genus Hypostomus, but no five of them appear more often in the trade. Special is of course H. luteus with its sail-like dorsal fin and the bright yellow coloration, but most species are “plecos”, brown or gray with black spots. In addition, most species grow quite […]

  • Pseudacanthicus sp. L273 Titanic

    12. November 2021

    The magnificent cactus catfish L273 Titanic, up to 30 cm long, originates from the Rio Tapajós. Its first import in 1998 was a sensation. Interesting about the animals, which are allowed to be exported from Brazil again since some time, is the very individual body pattern. All cactus catfishes are carnivores; towards non-species fishes they […]

  • Cochliodon sp. L360

    5. November 2021

    We have received some beautifully marked yellowseam catfish. This catfish originates from the middle Rio Jamanxin in Brazil and has not yet been correctly (i.e. scientifically) identified, neither in terms of genus nor in terms of species. However, it is quite possible that this catfish has already been scientifically described; young animals are quite inconspicuous, […]

  • L350 Panaque sp. Black Lyretail

    25. October 2021

    From Peru we received four specimens of a top rarity: L350. This peculiar fish does not fit any genus of loricariid catfish known to date. It originates from deep, turbid, very fast flowing water of the Peruvian Amazon, where it can only be caught with great difficulty and rarely. It is a carnivorous species whose […]

  • Spectracanthicus (= Oligancistrus) zuanoni L 354

    20. September 2021

    Spectracanthicus zuanoni L 354 originates from Rio Xingu and the Rio Iriri in Brazil. It has been described scientifically only in 2014 (see http://www.aquariumglaser.de/en/archiv.php?news_id=1195). The fish belongs to the same species as L 20, with however clearly larger white marks, so that the design reminds of a black net on a bright background. The reddish, […]

  • Curculionichthys sabaji

    1. September 2021

    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 […]

  • Ancistrini sp. L82

    30. August 2021

    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 […]

  • Pseudacanthicus sp. L79

    27. August 2021

    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 […]

  • Acanthicus sp. L155 Furo Maguari

    13. August 2021

    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 […]

  • Loricaria lata

    23. July 2021

    From the larger growing, mouthbrooding whiptail catfishes of the genus Loricaria only the very widespread L. simillima is in the trade from time to time, the others – after all there are 17 recognized plus several scientifically still undetermined species – are absolute top rarities. We have now received L. lata from Brazil. This species grows 20-25 cm long. It originates from the drainage of the Rio Tocantins. Like so many mouthbrooding loricariids this species is polychromatic, i.e. within one population there are quite differently marked animals. Our fish also show this polychromatism. Some are almost completely black, others rather bright with black bands and there are all conceivable intermediate stages; depending upon mood the animals also can change color.

    Among themselves our fish are peaceful. However, they are somewhat skittish and try to hide in the bottom when disturbed. A sandy bottom is therefore useful for the care, even if the fish then look in the close-up as if they had the white spot disease (Ichthyophtirius). We can reassure you: the animals are perfectly healthy.

    For our customers: the fish have code 266563 on our stocklist. Please note that we only supply wholesale.

  • LDA25 Parotocinclus jumbo

    12. July 2021

    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, […]

  • Parotocinclus haroldoi

    9. July 2021

    Perhaps the prettiest and at the same time most suitable otocinclus for aquaristics is Parotocinclus haroldoi. Concerning the coloring – yellow-white, shining spots on black underground – the species resembles the adonis pleco (Acanthicus adonis), remains however with maximally 4 cm (male) and at all-highest 5 cm (female) much, much smaller. Until now this species, […]

  • Pterosturisoma microps

    25. June 2021

    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 […]

  • Aphanotorulus sp. L11

    18. June 2021

    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 […]

  • Farlowella amazonum

    26. April 2021

    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 […]

  • Rineloricaria heteroptera

    9. April 2021

    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 […]

  • Pseudorinelepis sp. L95

    22. March 2021

    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. […]

  • Hypancistrus sp. “Nhamunda” L475

    15. March 2021

    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 […]

  • Lasiancistrus heteracanthus

    10. March 2021

    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 […]

  • Ancistrus macrophthalmus LDA74

    5. March 2021

    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 […]

  • Pseudolithoxus kelsorum L189

    1. February 2021

    Unfortunately this interesting catfish from Venezuela is offered only very rarely. It lives in the tributaries of the middle Orinoco. With a maximum length of 10 cm (only very rarely some specimens reach this size, the normal size is 6-7 cm) the species remains relatively small. Pseudolithoxus species are all quite flat, but P. kelsorum […]

  • Lorcaria simillima Bred

    11. January 2021

    Loricaria simillima has a very wide distribution in South America. It is found in the Orinoco-, Amazon- and La Plata basins. A result of this large area many different color forms are known, which differ clearly regarding coloration and pattern. The species occurs in different water types. Black water forms are more demanding in maintenance […]

  • Chaetostoma joropo (L445)

    18. December 2020

    The dotted Chaetostoma joropo is already for many years a popular sucker-catfish. Before its scientific description in the year 2016 it was given several names, e.g. sp. Spotted, cf. milesi, Villavicencio I, L187a etc. It originates from creeks in the catchment area of the Rio Meta in Colombia and therefore does not need to be […]

  • Parancistrus nudiventris, L31, LDA4, Peppermint Pleco

    13. November 2020

    This pleco from the Rio Xingu is an old friend, however, it received a scientific name only in 2005. It received the L-number 31 already in 1989.  The genus Parancistrus is closely related to the genus Spectracanthicus; the formerly often used genus Oligancistrus is invalid and declared synonymous with Spectracanthicus. The only difference between Parancistrus […]

  • Parotocinclus eppleyi

    6. November 2020

    One of the smallest loricariid species at all is Parotocinclus eppleyi, the Peppermint-Oto. The species is fully grown with a length of 3 cm (without caudal fin), but such animals can already be seen as xxl-format and are extremely rare. Usually the species, which is common in the upper and middle Orinoco, is 0.5-1 cm […]

  • Baryancistrus xanthellus L18, L81, L81n, L177

    14. October 2020

    About from the end of May to the end of September the season of the beautiful Golden Nuggets of the genus Baryancistrus lasts. Although the fish are considered to be extremely common in nature, are also found in shallow water and have been used as food fish since time immemorial, they were only scientifically described […]

  • Panaque cf. titan Shampupa L418

    28. September 2020

    The magnificent panaques of the nigrolineatus complex have long been sought-after aquarium fish. All species seem to grow around 40 cm long. One of the most spectacular species comes from Peru and was given the L-number 418. It is probably identical with the described species Panaque titan, but since this is not completely certain, the […]

  • Hypancistrus sp. L500

    7. August 2020

    In northern tributaries of the Amazon, namely the Rio Nhamunda (L475), the Rio Padauari (L499) and the Rio Uatumá (L500), there are very similar Hypancistrus, which have a relatively stocky body in common. In colour they resemble very much the Hypancistrus furunculus (L199) from the upper Orinoco. All four Hypancistrus are extremely variable in colour, […]

  • Ancistrus claro

    20. July 2020

    One of the smallest Ancistrus species is Ancistrus claro, which was known as LDA 8 before its scientific description. The catfish originates from clear water streams with a strong current in the upper part of the Rio Paraguay-Paraná river basin and becomes at most 6-8 cm long. The sexes are not quite as easy to […]

  • Pseudohemiodon laticeps

    10. July 2020

    Pseudohemiodon laticeps from Paraguay belongs to the longest known mouth-breeding Whiptail Catfish in the hobby, even if this large (up to 35 cm) species with its species-specific broad, triangular head was confused for a long time with the very similar, narrow-headed species P. platycephalus from Brazil. Mostly one sees both species in a fawn-brown colouring […]

  • Panaque schaeferi L203 L90c

    26. June 2020

    Among the largest loricariid catfish are some of the wood-eating Panaque species. Panaque schaeferi is one of them, the species will certainly grow to about 60 cm long. Since P. schaeferi was described on the basis of adult specimens, the assignment to the young animals belonging to it has never been scientifically confirmed. However, it […]

  • Panaqolus sp. L2

    5. June 2020

    The tiger pleco was already imported and presented in 1988; since then, unfortunately, no scientist has yet taken a closer look on the beautiful animals imported from Rio Tocantins in Brazil for the hobby; therefore, this relatively small, maximum 12 cm long, peaceful loricariid catfish still has no “correct” name, but has to be content […]

  • Sturisomatichthys leightoni

    13. May 2020

    Until recently, two genera of closely related whiptail catfish were distinguished according to anatomical features: the relatively short-nosed Sturisomatichthys with four described species and the relatively long-nosed Sturisoma with over 15 species. All species are popular aquarium fish because they are attractive and easy to breed. Unlike most other loricariid catfish they do not breed […]

  • L330 scientifically described: Panaque nigrolineatus laurafabianae

    23. March 2020

    Many fish scientists (ichthyologists) currently reject the concept of the subspecies. They argue that either there are definable characteristics, in which case it is a species, or there are no characteristics, in which case the form cannot be named. However, this concept has only limited relevance to reality; in the case of the large striped […]

  • Hypancistrus sp L471 “dwarf, big spots”

    16. March 2020

    From the Rio Ventuari in Venezuela we have received this extraordinarily beautiful Hypancistrus, which is very similar to H. inspector, H. contradens and L201, but has considerably larger spots, which also appear slightly yellowish. At least wild collected L471 seem to remain much smaller than the other mentioned Hypancistrus and hardly grow beyond 6 cm. […]

  • Pseudorinelepis sp. L95

    9. March 2020

    The loricariids of the genus Pseudorinelepis are the most heavily armored loricariids at all. They are widely distributed in the basins of the large South American rivers Amazon and Orinoco. The imported animals often look a little bit different, but scientifically only one species, P. genibarbis, is recognized at present. The coloration varies greatly individually, […]

  • Pseudacanthicus leopardus LDA7

    17. February 2020

    Species of Pseudacanthicus are also known under their popular name “cactus catfish”, for the species are very spiny and it is no good idea to catch a larger specimen with bare hands. Some species of Pseudacanthicus can reach one metre in length, but there are other species that grow up only to 25 cm. As […]

  • L128 Blue Phantom

    3. February 2020

    There is no „official“ paper that states in which genus this popular species from Venezuela should be placed in, but the catfish community agrees that it most probably is a member of the genus Hemiancistrus. Currently we have very nice youngsters of 3-4 cm length in stock, and some smaller as well as some larger […]

  • Ancistrus leucostictus

    22. January 2020

    From the Guyana states (French Guiana, Guyana and Surinam) there are for various reasons hardly any commercial ornamental fish exports. The ornamental fish originating there, e.g. the glow-light tetra, are therefore practically exclusively traded as bred specimens. This is also true for Ancistrus leucostictus, which was brought back from a tributary of the Mazaruni River […]

  • Hypancistrus spec. L 401

    6. December 2019

    This in the DATZ 12/05 newly introduced very beautiful Hypancistrus variant is currently available in small quantities. The animals remind in their habitus of L 333 and are sometimes confused with them. All in all L401 are more dainty, somewhat more stretched and reach only a total-length of maximum 12 cm, while L 333 can […]

  • Chaetostoma sp. L455 Tiger

    20. November 2019

    After longer time we could import again the beautiful Chaetostoma sp. L455 Tiger from Peru. Generally speaking, Chaetostoma species do not stand out because of their attractive colors, but this species makes a clear exception – at least the males. The females are colored considerably simpler. Some specimens show a red coloration in the tail […]

  • Pseudohemiodon sp. Peru II German Bred

    15. October 2019

    Floundercatfish are very popular with catfish lovers because they combine an interesting appearance with the interesting mouth brood care. Some species become quite big, so P. laticeps from Paraguay, that can become well and gladly 35 cm long, but there are also smaller species. Among the latter are two scientifically seemingly not yet described species […]

  • L134 Peckoltia compta

    13. September 2019

    The L-number catfishes are like us humans. There are pretty, very pretty and extraordinarily pretty specimens. To the latter group belong the L134 (Peckoltia compta) from the Rio Tapajós, which we currently have in stock. P. compta belongs to the most recommendable L-catfishes at all and unites all desired characteristics of this group in ideal […]

  • Ancistrus patronus and Ancistrus sp. “Rio Tocantins”

    13. September 2019

    In small numbers we received German bred specimens of these pretty bristle-noses. Ancistrus patronus is one of the numerous white dotted, black species and was known in the hobby as Ancistrus sp. “Puerto Ayacucho” and A. sp. “Rio Parucito” before its scientific description in February 2019; the numbers L125 and L150 were given to imported […]

  • Ancistrus sp. Paraguay

    28. August 2019

    After Paraguay had closed its doors for half a year for the export of ornamental fish, now imports from the southern country in South America reach us again. Among them also various Ancistrus species, which are often sent mixed. It has become common practice in the trade to call these animals Ancistrus tamboensis, which is […]

  • Zebra Otocinclus

    15. August 2019

    Currently we have two forms of very attractive Zebra-Otocinclus from Peru in stock.  The first species, Otocinclus cocama, is more commonly available. It shows a rather dense pattern of vertical black stripes on a light background and has the code number 274154 (see also http://www.aquariumglaser.de/de/otocinclus-cocama_de_1342.html_de_1342.html).  Only in small quantities and very rarely we get a […]

  • Leporacanthicus triactis VARIETIES

    8. July 2019

    Currently we received an import from Venezuela, which included small, only 3-4 cm long specimens of Leporacanthicus triactis, also known as L91. Among them are an unusually large number (approx. 10) of unusually beautifully drawn variants.  Normally small L91 do not look much different than the adults, only a little lighter in basic tone. But […]

  • Sensational: Red Pseudohemiodon apithanos!

    3. April 2019

    Recently we received red chameleon whiptails (Pseudohemiodon apithanos) from Colombia. The coloration of the eight specimens (a ninth was a “normal” apithanos, which we also received) is really fantastic. Red variants can be found in different loricariid catfish, think of Hemiloricaria and Ancistrus, but for the genus Pseudohemiodon they are not known yet.  The individual […]

  • Peckoltia sp. L135

    27. March 2019

    Currently is season for one of the most beautiful members of the genus Peckoltia, namely L135. The species originates from the Rio Negro and can be easily recognized by the “wormline-pattern” on the head. Only two other species of Peckoltia show a similar pattern: P. braueri from the Takutu river and P. sp. L121 from […]
