09. Characoids: tetra relationship (368)

  • Metynnis maculatus

    19. November 2018

    There are two rather similar species of the silver dollar genus Metynnis with a pattern of black spots. They differ mainly by the (externally not visible) number of the gill rakes and the number of scales along the long side of the body, but also somewhat in relation to the body shape. We currently call […]

  • Moenkhausia heikoi

    12. October 2018

    For the first time we could import, even if only in very limited numbers, this tetra from the Rio Xingu described only in 2004. The animal became known in 2001, when Rainer Stawikowski presented the fish as “Hemigrammus sp. Xingu” in the journal DATZ. The scientific description took place in 2004, twice and almost simultaneously: […]

  • Serrasalmus compressus – a very interesting piranha from Peru

    8. October 2018

    Recently we obtained a shipment of piranhas from Peru. The fish are 5-9 cm long. At the first glimpse the shipment could be told apart into two phenotypes. First, there were fish with comparatively small spots, a lot of red coloration in the anal fin and a comparatively thin black border on the caudal fin. […]

  • Serrasalmus rhombeus

    26. September 2018

    From Brazil we received wonderful, 12-15 cm long Serrasalmus rhombeus. This species grows 35 cm, maybe even 50 cm long, making it one of the largest piranha species of all. One can recognize adolescent S. rhombeus quite well by the combination of ruby red eye, a shoulder spot which is not substantially larger than the […]

  • Jupiaba sp. „Cherry Spot“

    29. August 2018

    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 collector 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 the broadest […]

  • Acestrorhynchus heterolepis and A. microlepis

    24. August 2018

    For the first time we were able to import Acestrorhynchus heterolepis, which has been described scientifically as early as 1878 by Cope from Peru. Our specimens originate from Venezuela; it was a mixed shipment of these fish and A. microlepis*. A. heterolepis has two dark horizontal bands, thus reminding a bit in A. isalinae; however, […]

  • Aphyocharax paraguayenis

    22. August 2018

    This small, about 4.5 cm maximum length reaching tetra belongs to the most attractive species of tetra at all. The species is very hardy and undemanding and can be easily bred in huge numbers. It is a fish of the subtropical regions and doesn´t even require a heater. In the wild, water temperatures between 16 […]

  • Catoprion mento

    17. August 2018

    In autumn last year we were able again to import wimple piranhas (Catoprion mento). We kept some of the fish, which had at the time of importation a length of 2-3 cm in our fishhouse and now we can offer them in an optimal size – 5-6 cm long. In the wild, C. mento is […]

  • Pseudochalceus kyburzi

    10. August 2018

    After many 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 […]

  • Hyphessobrycon herbertaxelrodi „Smoke“

    27. July 2018

    This is a very interesting and beautiful new sport of tetra. One can only guess that it belongs to the species Hyphessobrycon herbertaxelrodi, but there is no other species known in the hobby that fits better. Two characters make this fish very desirable: the extraordinary strong schooling behaviour and the intensive dark coloration of the […]
