Platy (fish)

Platy is a common name of freshwater fish in the genus Xiphophorus that lack a "sword" at the bottom of their tails. Both species are livebearers, similar to other fish of the family Poeciliidae, such as the guppy and molly. Platies are native to the east coast of Central America and southern Mexico.^[1][2]

The two species, the southern platyfish and the variatus platy, have been interbred to the point where they are difficult to distinguish. Most platies now sold in aquariums are hybrids of both species.^[2]
