Most "P. wingei" from the Campoma region found in the hobby today are descended from those originally collected by Phil Voisin (Philderodez). The most popular collecting site in the Campoma region for "P. wingei" has been the Campoma bridge location. "P. wingei" phenotypes collected from the Campoma bridge location are identified by a numbering system from 1 through 70. "Poecilia wingei" from the Campoma region are also known as the Campoma guppy. "Poecilia wingei" from the Cumana region were originally known as the Endler's guppy. Ender's livebearer originally discovered in 1975 by John Endler and are found in Laguna Patos and in the lagoon's connected streams and canals, was actually a micropoecilia species that are believed to extinct. In 2009 the Schories et al. publication broadened the definition of "P. wingei" to include Endler's livebearer. Most "P. wingei" from the Cumana region found in the hobby today are descended from those collected by Armando Pau and were line bred and distributed to hobbyists by Adrian Hernandez (AdrianHD). "P. wingei" from the Cumana region are also known as the Cumana guppy. El Tigre are "Poecilia wingei" collected from the El Tigre stream in the Campoma region of Venezuela. The El Tigre stream is not connected to Laguna Campoma so the El Tigre belong to their own distinct population. All El Tigre found in the hobby today are descended from those collected by Phil Voisin (Philderodez). Endler's livebearers are hardy and undemanding in the aquarium, though they prefer hard, warm water. The warmer the water, the faster they will grow; however, this also seems to shorten their lifespans. They can be kept at 18–29 °C (64–84 °F), but their optimum temperature seems to be 24–27 °C (75-81 °F). This is slightly higher than their guppy cousins, which prefer 23–25 °C (73-77 °F). They do best if kept in tanks with plants (preferably live plants, but fake will do) to give them hiding places and (although they may be less likely than guppies to eat their own young) give the fry a better chance at survival.
