09. Characoids: tetra relationship (380)

  • Triportheus cf. nematurus

    25. March 2020

    The unusual genus Triportheus contains very interesting, somewhat larger species. Depending on the species these fish attain a length of 15-25 cm. Currently 16 species are distinguished that inhabit all major river systems of South America. From time to time we import members of the genus from Paraguay. Two species can be found there, namely […]

  • Moenkhausia hemigrammoides

    18. March 2020

    From Venezuela we recently received „feather tetras“. This is what we used to call tetras that have a striking black stripe in the anal fin, accompanied by a white line in front of it. In general, however, the term “feather tetra” is alternatively used to species of the genus Hemiodus or Hyphessobrycon copelandi. Our “feather […]

  • Brittanichthys axelrodi

    13. March 2020

    From the catchment area of the Rio Negro these interesting, rarely traded characins reached us. Brittanichthys axelrodi is a true black water fish, which should be kept at pH 4.5 – 6 and low hardness. Filtering via peat can be very helpful here. In addition to improving the chemical parameters, the bactericidal effect of peat […]

  • Pseudochalceus kyburzi

    11. March 2020

    After several years we finally were able again to import this very beautiful tetra from Colombia once more. This species attains usually a length of about 5 cm, the largest one reported had about 8 cm in length. In respect of the general look and the behaviour Pseudochalceus kyburzi can be best compared with the […]

  • Serrasalmus geryi

    8. February 2020

    If ichthyologists were superstitious, they would surely believe that Serrasalmus geryi was sent to them so that they would not despair. No other species of piranha can be identified at all stages of its life as reliably and unequivocally as this endemic (i.e. it occurs exclusively there) of the Rio Tocantins in Brazil. The reddish-brown […]

  • Nannostomus anduzei

    24. January 2020

    Finally we could import one of the smallest fish species of the Amazon basin again: Nannostomus anduzei. They stay – including the tail fin – usually smaller than 2 cm. Our current import came via Manaus, so they are Brazilian animals; the specimens on which the original description was based came from the department Amazonas […]

  • Hemiodus thayeria

    25. November 2019

    Shortly after the first import of Argonectes longiceps we were able to import another feather tetra, which has not yet been seen, at least by us: Hemiodus thayeria. This beautiful, elegant fish comes from the border area of Brazil and Colombia at the Rio Negro. The type specimen was already collected in 1925 by Carl […]

  • Serrasalmus cf. sanchezi “Pará”

    18. November 2019

    When trying to identify piranhas, one often pokes in the dark. The differences between juvenile and adult forms are dramatic, both in terms of physical and color characteristics. Over the decades that we have imported young piranhas from all parts of South America, some characteristics have proved to be quite reliable in combination: 1- is […]

  • Gnathocharax steindachneri

    15. November 2019

    In the natural habitat of the cardinal tetra food sources are very scarce. So it is really astonishing how many species can exist there. However, many of them stay very small. Good luck for the aquarium hobby, for they all make very good ornamental species! Even a predatory species of that biotope is such a […]

  • Argonectes longiceps

    8. November 2019

    We could import a quite unusual tetra for the first time in some specimens from Colombia: Argonectes longiceps. Although the species is inconspicuously colored, it looks quite attractive with its black and white tail fin pattern. They are peaceful animals which, in contrast to the closely related Hemiodus species, have a normal, i.e. horizontal swimming […]
