Moon, No one really knows the parentage of all the aquarium mollies, especially blacks. Black morphs of several molly species occur in the wild, but the most common are from Poecilia sphenops. Some are also from P. latipinna. The sail fin on the fish you bought suggests latipinna, velifera (or other tropical) heritage, but the red margin on the fin suggests some other parentage also, even including sphenops. The short of it is, mollies in the aquarium trade are derived from lineages long ago established from a variety of parents. Unless you bought fish from a breeder who could document his fish, I would just call them "black mollies." That is sort of like saying that your pet dog is a dog.
