Endler's Livebearer Poecilia wingei

Endler's Livebearer is a freshwater fish native to Venezuela's Paria Peninsula. It is now extinct from its previous stronghold in the brackish Laguna de Patos due to water pollution.

Like guppies, males are smaller, slimmer and more colourful than females, with long flowing dorsal and tail fins. Females are "live bearers" - they give birth to live young rather than laying eggs.

In captivity, Endler's Livebearers have been interbred with colourful Guppies to produce various (male) colour and tail-shape variations, although generally the two species (of the same genus) prefer different water conditions. Most of the many Poecilia species are called "Mollies", except the Guppy and Endler's.
