18. Toothcarps: Killis and Livebearers (251)

  • Xiphophorus hellerii “Jalapa”

    5. January 2022

    When you first see this slender, splendidly colored swordtail wild form, you involuntarily think: this is no X. hellerii! And yet, when X. hellerii was first described in 1848, exactly such animals became the type specimens. The traveler of the royal imperial horticultural society Karl Heller discovered and collected the animals in clear streams of […]

  • Xiphophorus nezahualcoyotl

    20. December 2021

    We have just obtained very attractive offspring of the “Northern Mountain Swordtail”. The fish are young adults, i.e. the sword of the males is still relatively short. For comparison we show here also an adult pair of another strain. In former times X. nezahualcoyotl was considered as a local variant of X. montezumae. The name […]

  • Poecilia wingei Campoma No31 Snake Blue

    6. December 2021

    Infinite is the variety of colors, patterns and color combinations possible in wild guppys. In natural biotopes no two males are alike. There are multiple mechanisms, genetic and biological, that ensure this. This is also true for the two wild guppy populations assigned to the species Poecilia wingei: Campoma and CuminĂ¡. However, if individual males […]

  • Filigran Guppys – King Cobra Guppys

    3. December 2021

    The Filigran Guppys belong to the most popular Guppy forms. They have a body pattern of squiggles and dots, which is also called “Snakeskin” or King Cobra. This body pattern sometimes appears in wild Guppys, but it was not until the 1950s that it received more attention and was genetically characterized by M. Dzwillo in […]

  • Girardinus uninotatus

    5. November 2021

    From the currently seven accepted species of the genus Giradinus only G. metallicus and occasionally G. falcatus are offered in the trade. We have now received a small number of G. uninotatus from a breeder. They are really no color miracle, but their pretty apricot color is quite interesting. The species oirginates from Cuba. The […]

  • Poecilia mexicana “Campeche”

    8. October 2021

    The wild mollies are – from a zoological-systematic point of view – certainly one of the most difficult fish groups at all. Not without reason, science has been wavering between two extreme views for over 100 years: the first states that all wild mollies belong to only one, highly variable species, which would then be […]

  • Guppy Endler

    8. October 2021

    No fish species is as changeable as the Guppy. There are no two males in nature that are exactly alike in color. This is true for all four Guppy species (Poecilia reticilata, P. wingei, P. obscura and P. kempkesi), which therefore cannot really be distinguished from each other externally (genetically, however, they can). In the […]

  • Procatopus aberrans

    1. October 2021

    Again we could import the lampeye fish Procatopus aberrans from NIgeria; unfortunately we do not know the location where they were collected. However, we know that our supplier occasionally receives fish from Cameroon. Anyway, the current imports are a bit more graceful in body structure and the upper half of the iris lacks the red […]

  • Guppy Japan Blue and Japan Red

    24. September 2021

    There is a number of tail fin shapes of the guppy, which have been standardized by the guppy breeders. As a rule, however, these breeds are only found at private breeders. In the pet trade the triangle guppies dominate in such a way that aquarists, who do not inform themselves specifically about guppies, could get […]

  • Xiphophorus signum

    24. September 2021

    This species of swordtail is only very rarely offered in the trade. At the first glimpse one may think that they are a variety of the common swortail X. hellerii, but the species X. signum is much more slender. The mark that is responsible for the scientific name (latin signum = sign) is always good […]
