Rosy Reds Pimephales promelas are really nothing more than fathead minnows given a fancy name and sold in aquarium shops as feeder minnows for other fish. The difference being that the rosy reds have an unusual color as compared to the regular drab fathead minnow. These reddish orange fathead minnows are sold under a variety of names such as tuffy, rosy!
These minnow are native to the eastern and central states but their use as bait has had the effect of introducing them into a number of locals outside of their normal range.
