09. Characoids: tetra relationship (391)

  • Inpaichthys kerri “Super Blue”

    18. November 2020

    There is a nice story about the discovery of the king tetra, which we don’t know if it’s true, but it’s worth telling: In the Instituto Nacional de Pesquisas da Amazônia (INPA), Manaus, Brazil, aquatic plants were kept in an aquarium. Fish were actually not in it. But suddenly, as if from nowhere, cute baby […]

  • Serrasalmus elongatus

    11. November 2020

    This very elongated Piranha can be confused hardly with other species because of its characteristic body shape. Type locality is the Rio Guaporé, Mato Grosso, Brazil. Aquaristic imports are mostly from Peru.  Serrasalmus pingke from Venezuela was described from the Rio Apure. The holotype (54 mm long) is shown in MACHADO-ALLISON (2002); it has a […]

  • Serrasalmus humeralis

    2. November 2020

    The identification of many Piranha species is difficult. One of the earliest described piranha species and therefore with many taxonomic problems is Serrasalmus humeralis. Valenciennes was the first descriptor in 1850, but there is no question that he had received the type specimen, for which he states “Amazon” as the type locality, from Castelnau. In […]

  • Pyrrhulina brevis

    26. October 2020

    The characins of the genus Pyrrhulina can be better compared to cichlids than to other characins in terms of their behavior. The males occupy small territories in the breeding season, color themselves splendidly and defend the spawn energetically until the young hatch. The generic name Pyrrhulina means “small bullfinch” because the males of many species […]

  • Mylossoma aureum

    23. October 2020

    The magnificent pacus of the genus Mylossoma that reach at most approximately 30 cm of length (the average length in the nature amounts to approximately half of this measure), are only with difficulty determinable. The last revision from 2018 (Mateussi et al.) distinguishes 4 species south of the Andes (another species, M. acanthogaster, occurs in […]

  • Jupiaba sp. „Cherry Spot“

    19. October 2020

    Once more we were able to import a new species of tetra from Venezuela which does not resemble to any species known to us. According to the supplier the animals were collected in small brooks in the surroundings of Puerto Inirida. There are no doubts that our new imports belong to the Astyanax relationship in […]

  • Anodus orinocensis

    9. October 2020

    From Venezuela we could import Anodus orinocensis for the first time. As a young fish A. orinocensis often lives in mixed shoals with Hemiodus gracilis. The two species really look amazingly similar, but Anodus is a Aufwuchs eater, and also filters the water for small organisms and swims mostly in “normal” horizontal swimming position, while […]

  • Metynnis lippincottianus

    31. July 2020

    Silver Dollars, which are the piranha relatives that eat mainly vegetable food, usually grow quite large, most species grow to over 20 cm, some to 40-60 cm long. The smallest known species is Metynnis lippincottianus, of which we can offer sexually mature specimens. They are currently 8-12 cm long, more than 15 cm total length […]

  • Serrasalmus immaculatus

    22. July 2020

    In great parts of South America there are large (up to 50 cm) piranhas, which usually become black when they are old. Another common feature of these piranhas is a red iris. It is currently common practice to refer to all these animals as Serrasalmus rhombeus because they are indistinguishable as adult fish. However, young […]

  • Phenacogrammus interruptus

    13. July 2020

    The Congo Tetra, Phenacogrammus interruptus, sometimes also called the Blue Congo Tetra, is the only one of the approximately 350 tetra species in Africa that is always available in pet shops. This is of course due to its beautiful colouring, which shimmers differently on the flanks depending on the incidence of light, the reddish-brown back, […]
