Rosy Red Minnows (Pimephales promelas) are actually fathead minnows, but due to a genetic mutation they are a light "rosy" color.

Most often sold as "feeder fish", Rosy Reds, if cared for properly, can prosper, and provide a clean, live food for your carnivorous fish. Since they are schooling fish and enjoy staying in groups, they provide a attraction in larger tanks, even when there is no threat around.
