09. Characoids: tetra relationship (364)

  • Pyrrhulina spilota

    12. July 2019

    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 […]

  • Hoplias malabaricus “Venezuela”

    1. July 2019

    We have already mentioned it: currently we have three species of the genus Hoplias from Venezuela in our stock. The common wolf tetra (Hoplias malabaricus) has a huge distribution area, but it is very likely that this “species” proves to be a species complex consisting of several, at least partially undescribed species.  With the “Hoplias […]

  • Hoplias curupira

    28. June 2019

    Right now we have three Hoplias species from Venezuela in our stock. Hoplias curupira belongs to the real rarities and is accordingly sought after among predatory fish fans. With a final length of about 40 cm the stocky species remains relatively small. It belongs within the genus Hoplias to the so-called H.-lacerdae group, which besides […]

  • Moenkhausia simulata

    14. June 2019

    We obtained a somewhat irritating import of a very rare species of tetra last week from Peru. In all probability, it is Moenkhausia simulata; however, our new import differs slightly from the previously known M. simulata in coloration. All other tetra species with a pattern of several horizontal stripes (Astyanax lineatus, A. kullanderi, A. superbus, […]

  • Hyphessobrycon peruvianus

    27. May 2019

    Three species of tetra in northern South America are obviously close relatives to each other and often confused: Hyphessobrycon loretoensis from Peru, H. metae from Colombia, and H. peruvianus, again from Peru. From these, H. loretoensis has been portayed here: http://www.aquariumglaser.de/en/hyphessobrycon-loretoensis_de_1188.html. Currently we were able to import the second Peruvian species once more, H. peruvianus, […]

  • Synaptolaemus latofasciatus

    17. May 2019

    Finally we managed to import again some specimens of this unusual “striped sock” from Venezuela. The species – there is just the one in the genus Synaptolaemus – was long known under the name S. cingulatus, until Britzki et al. discovered that the species described as Leporinus latofasciatus by Steindachner in 1910 was identical with […]

  • Pseudanos winterbottomi

    8. May 2019

    In the past years we received this rare headstander, scientifically described only in 2005, which is known from the Orinoco in Venezuela and the Tapajós in Brazil, only very occasionally as a by-catch from Venezuela. Mostly the animals were found among Anostomus ternetzi or Pseudanos trimaculatus. Now we could finally import some specimens of this […]

  • Tyttocharax cochui

    26. April 2019

    Finally we were able to import once more one of the most charming dwarf tetras at all: Tyttocharax cochui. These very lively and absolutely peaceful blue flashes become only 1.5-2 cm long. The story how T. cochui was discovered is quite interesting.They were imported for the first time in April 1949 to Germany – as […]

  • Hoplerythrinus unitaeniatus “Orinoco”

    26. April 2019

    From Colombia we received an import of the striped wolf tetra, Hoplerythrinus unitaeniatus. The systematics of these almost over the entire South America spread fish is poorly understood. Only the one species, H. unitaeniatus, is recognized commonly, but there are a lot of synonyms, among them the (without justification) occasionally recognized species H. cinereus (Trinidad […]

  • Copella nattereri

    12. April 2019

    It took until the year 2006 that the tetra specialists Axel Zarske and Jaques Géry found out that the species described as Copella nattereri was practically not present in the hobby and that the red spotted Copella, which was named C. nattereri until then, was not known to science yet! So Zarske and Géry described […]
