18. Toothcarps: Killis and Livebearers (246)

  • 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 […]

  • Poecilia wingei Blue Star

    25. August 2021

    Poecilia wingei is widely distributed in the hobby after its best known local variant as Endler´s Guppy. It remains much smaller than the normal Guppy and is very popular with many aquarists because of its graceful body shape.  Just as with the common Guppy, numerous local forms can be observed with P. wingei. The ancestor […]

  • Platy Wagtail Pointed Tail

    16. August 2021

    The “pointed tail” mutation, in which the middle caudal fin rays are elongated, appeared relatively late: the first specimens appeared on the market in the 1980s. It originated in the Southeast Asian large-scale breederies. The characteristic, which first appeared in the Platy (Xiphophorus maculatus), can also be transferred to other Xiphos, but the pointed tail […]

  • Guppy Kohaku Koi Tuxedo

    6. August 2021

    Guppy breeders are currently very active again and bring new, attractive strains on the market. The Guppy Kohaku Koi Tuxedo combines two special characteristics: The Kohaku factor, which causes males and females to have a red head combined with a red caudal fin and red dorsum; and the Elephant Ear factor, which causes the greatly […]

  • Guppy Neon Green Lyretail

    9. July 2021

    Aquaristics is unimaginable without the multitude of colorful livebearer breeding forms. However, this also means that there is competition between the different breeding lines for the buyers’ favor. A good name clearly sells. And even if, strictly speaking, the Neon Green Lyretail is neither neon green in color nor has a lyre tail – who […]

  • Xiphophorius variatus “Hotel Taninul” and “Code 1243”

    2. July 2021

    We have already introduced several wild strains of Xiphophorus variatus, which rightly bears its scientific species name (variatus = variable).  Now we have again two new variants on offer, both are German bred ones, descended from wild populations. The first is a pretty speckled fish discovered and brought back on a scientific collecting trip in […]
