Poecilia Wingei - in The Aquarium

In The Aquarium

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. Some of them are determinedly suicidal jumpers, so a cover on the tank is a must.

Endler's may be fed any of a variety of dried, frozen, or freeze-dried foods, as long as the food will fit into their relatively small mouths. They are particularly fond of frozen bloodworms, and will often attempt to consume worms nearly as long as they are.

Endler's are very responsive to light and movement. After they learn that humans equate to food, human movement will trigger frantic "begging", regardless of whether the fish are actually hungry or not. Darkness will signal it is time to sleep. Most Endler's will sink to the bottom of the tank and lie there until the light returns, although in community tanks with larger fish that inhabit the depths, some Endler's will "sleep" near the top.
