09. Characoids: tetra relationship (445)

  • Cyphocharax multilineatus

    21. November 2022

    This interesting species, which we obtained from Venezuela, belongs to the Curimata-relationship. At the first glimps it reminds one strongly to the well known headstander (Chilodus punctatus), but it can be easily recognized by the black stripe through the eye. Moreover, Cyphocharax swims in a “normal” horizontal way. Cyphocharax feed on Aufwuchs and look the […]

  • Charax cf. michaeli

    16. November 2022

    There is a conspicuous group of tetras in South America, which we will call “humpback tetras”. They have attracted the interest of researchers since the beginning of fish science (ichthyology), but proved to be a very difficult group in terms of their relationship classification. There are three genera of humpback tetras, which can hardly be […]

  • Nannostomus eques Peru

    24. October 2022

    The tetras of the genus Nannostomus, called pencil fish because of their somewhat stiff swimming style reminiscent of traveling zeppelins, have been among the most popular ornamental fish for decades. They are very beautiful, usually peaceful and remain small. Three species swim at an angle with their heads up: Nannostomus eques, N. britzkii and N. […]

  • Curimatopsis evelynae

    14. October 2022

    The tetras of the genus Curimatopsis are widely distributed in South America. The prettiest species is C. evelynae. Nevertheless, this attractive fish has hardly found its way into aquariums so far. C. evelynae grows to a maximum length of 4 cm. The males can be recognized by their clearly higher caudal peduncle, furthermore the females […]

  • Hypomasticus julii

    7. October 2022

    In 1996, ichthyologists Santos, Jegu, and Lima described an unusual Leporinus from the Rio Xingu and Trombetas as L. julii. The new species is closely related to L. pachycheilus, an extremely color variable Leporinus species. Unique to L. julii, which was named in honor of Júlio Garavello, is the completely underslung mouth and teeth position. […]

  • Thayeria obliqua

    28. September 2022

    Unfortunately the beautiful penguin tetra, Thayeria obliqua, from the upper Amazon is offered only very rarely, in contrast to its cousin T. boehlkei, which can always be found in the trade. In the trade are only offsprings of T. boehlkei; it originates from the Rio Xingu drainage in Brazil. A third species, T. ifati from […]

  • Pyrrhulina spilota

    2. September 2022

    The tetras belonging to the genus Pyrrhulina combine the advantages of two basic groups of ornamental fish. The first group are the schooling species that are always visible and swim merely in the open water: tetras and barbs. The second group has a fascinating behaviour and takes care for the brood: the cichlids and the […]

  • Carnegiella strigata-vesca

    24. August 2022

    The marble hatchetfish (Carnegiella strigata) is the ideal aquarium fish. It remains small (4 cm), is peaceful and has an interesting coloration. The species is widely distributed in South America (Brazil, Ecuador, Bolivia, Colombia, Guyana, Peru and Suriname) and common. That is why it is almost always found in the offer of the ornamental fish […]

  • Hyphessobrycon epicharis

    19. August 2022

    Since the first scientific description of Hyphessobrycon epicharis in 1997, this species is on the dream list of many tetra enthusiasts. Unique feature of this Rosy tetra is the shape of the shoulder spot, which distinguishes it from all other species.  The specimens on which the first description was based came from the upper reaches […]

  • Gymnocorymbus bondi (formerly: G. socolofi)

    19. August 2022

    It has been a long time since we could import the last time the beautiful tetra Gymnocorymbus bondi from Colombia. Very small animals remind strikingly of the Yellow Tetra (Hyphessobrycon bifasciatus), but with increasing growth the shape changes more and more to the one known from Gymnocorymbus. Now we finally got this orangefin tetra once […]
