10b. Catfishes: Suckermouths, Plecos and L-numbers (237)

  • 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 […]
