18. Toothcarps: Killis and Livebearers (265)

  • Micropoecilia picta Red Surinam

    11. November 2022

    At first sight the Micropoecilia species resemble the Guppy; however, they are not closely related. Nevertheless Micropoecila picta is often called “swamp guppy” in Surinam, because the species is not only very common in general, but also very common in swampy habitats. Now one could think, the care of such fish of slightly disreputable origin […]

  • Poecilia (Mollienesia) sphenops Marble Ancient

    19. October 2022

    The livebearers are the backbone of aquaristics. The hobby would be unimaginable without Guppy, Platy, Molly and Co. We notice two trends in the breeding of these fish: one deals with the wild forms, which were very rare or not available at all in the trade; and the other develops new, colorful breeding forms, but […]

  • Lamprichthys tanganicanus

    16. September 2022

    With a maximum length of 14 cm, the Tanganyika lampeye fish is the largest lampeye fish at all. It is found exclusively (= endemic) in Lake Tanganyika, where it lives in huge schools along rocky coasts. It is a breathtaking sight when such a shoal, comprising several thousand individuals, comes swimming around a cape like […]

  • Aphyosemion (Chromaphyosemion) bivittatum “Funge”.

    16. September 2022

    The Funge is a river or, rather, estuary in southeastern Cameroon in the district of Ndian. The Funge is less than 40 km long and is part of a system of coastal marshlands whose best known outlet is the Rio del Rey. This in turn is in contact with the Cross River drainage, which forms […]

  • Poecilia (Mollienesia) sphenops RED

    9. September 2022

    The breeders in Southeast Asia have realized a new color variation of the good old Black Molly, which they call “Red”. This is not a solid red fish, like for example a red swordtail, but the breeding form “Red” of the Molly has red spots in different intensity on the scales. When viewed from above, […]

  • Guppy Endler “Smoky Mary“

    17. August 2022

    Breeders can’t get enough of creating new color combinations in Endler guppies. The latest thing is the “Smoky Mary”, an Endler in which the entire back appears covered in smoke, which intesivates to a deep black during courtship. Even though we don’t know the breeding way: the females of Smoky Mary are normally light colored, […]

  • Xiphophorus signum

    12. August 2022

    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 […]

  • Nothobranchius rachovii ALBINO

    11. July 2022

    Rachows Nothobranch (named in honor of Arthur Rachow, therefore in the common name with “w” at the end) belongs not only to the longest serving, but also to the timelessly most beautiful Killifishes in the aquarium. The orange color form of Beira is the most common in the trade, and has been continuously maintained in […]

  • Xenotoca doadrioi

    1. July 2022

    In the past, this particularly pretty goodeid (Xenotoca doadrioi) was known as “Xentotoca eiseni San Marcos”. Unfortunately, the species, which was only “officially” described as a distinct species in 2016, is highly endangered. More than 50% of the originally known populations have already disappeared, with the rest showing a steady downward trend. The causes are […]

  • Nothobranchius patrizii

    1. June 2022

    The nothobranchs (Nothobranchius) represents with N. furzeri one of the shortest-lived vertebrates of the world. Only the marine goby Eviota sigillata tops it, with it (in nature) never an animal became older than 59 days. In the case of N. furzeri, the time between hatching from the egg and death from old age is also […]
