Poecilia reticulata
The scientific name for a black molly is Poecilia sphenops. It is a species of fish that belongs to the Poeciliidae family.
Poecilia reticulata is the current taxonomic name. They used to be Lebistes reticulata.
Yes, guppies are freshwater fish. Their scientific name is Poecilia reticulata.
Yes, guppies are Freshwater Fish. Their scientific name is Poecilia reticulata.
The guppy was "Lebistes reticulatus" for many many years but now the taxonomists in their ultimate wisdom, have decided that the guppy should be in the same classification as the Molly. Now the Guppy is correctly called "Poecilia reticulata".
I had some success breeding a male Xiphophorus helleri(swordtail) with female Poecilia reticulata (guppies) back in the early 1990's. Although of different genera, these two freshwater aquarium fish are in the same family. Hybridization may be possible, but it is doubtful that the offspring will be able to reproduce.
Platys are Xiphophorus sp. Mollys are Poecilia sp. As you can see they are of entirely different species and so obviously they can not breed with one another.
