The main types of platy fish that are available in the aquarium trade today are actually hybrids of two closely related species: the southern platyfish (Xiphophorus maculatus) and the variatus platy (Xiphophorus variatus).
The two species have been interbred for many generations in the aquarium trade. At this point, it’s almost impossible to tell the two apart since any tank-bred fish was likely hybridized at some point.
