There is even a variety called the Mickey Mouse. They can be a very active tropical fish if given good water conditions. The female Platy is usually larger than the males of the same age. Females can reach a size of up to 2.5 inches whereas the males usually get to be about 1.5 inches. Breeding them is fairly easy since they are livebearers.
Platies will accept most fish foods including flakes, frozen, live and freeze dried foods. Try to vary their diet for optimum health and coloration.
