18. Toothcarps: Killis and Livebearers (235)

  • Aphyosemion australe

    7. May 2021

    The “Cape Lopez” (Aphyosemion australe) is one of the longest serving killifishes. It was discovered due to aquarium imports from Gabon (Ogooué River estuary, Port-Gentil, Cape Lopez, northwestern Gabon), from where it was first brought in 1913. In 1921 Arthur Rachow described it as a new species, then cautiously as Haplochilus calliurus var. australis. The […]

  • Xiphophorus maculatus “Tabasco”

    23. April 2021

    Hearing the name Tabasco, the first thing that comes to mind for a Central European is the spicy chili sauce. However, the Platy (Xiphophorus maculatus) that bears this name is neither particularly fiery nor particularly red – it merely originates, like the chili sauce, from the Mexican state of Tabasco, where this population was first […]

  • Poecilia velifera Silver

    6. April 2021

    Silver mollies are among the most popular livebearers. Most of the silver mollies in the trade are a breeding form of Poecilia latipinna. Since the species Poecilia latipinna, P. sphenops, P. mexicana and P. velifera can be crossed and color characteristics and certain fin shapes (e.g. lyratail) are transferred to the hybrid young, the desired […]

  • Xiphophorus hellerii “Yucatan 2”

    1. April 2021

    From a German breeder we received this extraordinarily attractive wild form of the swordtail. Unfortunately we could not find out where exactly and by whom these animals were collected. It could only be determined that they were originally brought from Yucatan (Mexico). As a distinction to the completely different looking X. hellerii “Yucatan” (see https://www.aquariumglaser.de/en/fish-archives/xiphophorus_hellerii_yucatan_en/) […]

  • Aplocheilus blockii

    26. March 2021

    The Green panchax (Aplocheilus blockii) is one of the tiniest and most beautiful species of panchax in Asia. We were able once more to import the species from Kerala (South India). Its maximum length is around 3 cm, at least as far as wild collected specimens are concerned. Aquarium specimens may become a bit larger […]

  • Poecilia velifera Green

    5. March 2021

    From the sailfin molly, Poecilia velifera, which originates in the hot coastal regions of Mexico, there are mostly cultivated forms in the trade: Golden, chocolate, leopard, dalmatian, black, etc.. The “green” wild form is much rarer, although they are very colorful animals. All sailfin mollies on the market are bred ones. The huge dorsal fin […]

  • Poecilia salavatoris

    15. February 2021

    The Liberty Molly is a long-established aquarium fish that was imported into the hobby before World War 2 and has never disappeared since. However, our aquarist forefathers considered any short-finned molly to be Poecilia sphenops, and so the Liberty Molly was also treated as a variant of this species. Today we distinguish again a lot […]

  • Procatopus aberrans

    15. January 2021

    We obtained very nice Procatopus aberrans from Nigeria. These lampeyes are very peaceful schooling fish that live near the water surface or at least in the upper third of the water column. In contrast to most other species of lampeye that have an iridescent blue zone in the iris, in P. aberrans the iridescent zone […]

  • Poecilia velifera “Dalmatiner”

    8. January 2021

    At least three species of mollies are the parent species of the numerous breeding forms that exist of these fish today: Poecilia sphenops, P. latipinna, and P. velifera. Possibly P. mexicana was also involved, but this is unclear, as this species was long considered a synonym of P. sphenops. Some color and fin characteristics could […]

  • Xiphophorus montezumae

    4. December 2020

    With the swordtails (Xiphophorus), the males carry a sword-like extension at the low end of the tail fin in many species. This is a luxury structure, that serves the intraspecific communication. Sword-bearing males appear especially sexy on the females and especially intimidating on male conspecifics. The also with primates (the ape-like animals) well known game […]
