Poecilia wingei gets its common name from Dr. John Endler, who rediscovered the species in Venezuela and introduced them into the pet trade. Males get up to 1 inch (2.5 cm) long, are slender in profile, and have all the vibrant colors and patterns. Females can reach 1.8 inches (4.5 cm), have a rounder abdomen, and are usually tannish-silver in color.
 
Are Endlers the same as guppies? No, although they are closely related and able to spawn together to create offspring that are fertile. Poecilia wingei is an Endler’s livebearer, Poecilia reticulata is a guppy, and a hybrid of the two is an Endler guppy.
 
What fish can live with Endlers? They get along with just about any peaceful community fish that are not big enough to eat them, such as smaller tetras, danios, and cory catfish. If you find that the Endler population is growing out of control, you can add some African dwarf frogs or other predatory fish that will eat some of the fry while leaving the adults alone.
 
What Do Endler’s Livebearers Eat?
The good news is that they are not picky eaters and will consume anything small enough to fit in their mouths, such as flakes, pellets, Repashy gel food, and daphnia. They are great at scavenging for food all over the aquarium, both at the water surface and substrate level, and have even been known to pick at algae if they’re hungry enough. Bottom line: make sure to feed them a variety of foods so they get all the necessary nutrients to boost their immune system and display vibrant coloration.
