Breeding males have a chevron-shaped black blotch at the origin of the caudal fin separated from a dark black stripe along the side, and have orange caudal and anal fins.[2] Distribution and habitatThe fish is the only fish found exclusively in Alabama[3], primarily upland in the Choctawhatchee River system before it merges with the Pea River.[2][4] Orangetail shiners are found in sand-bottomed and silt-bottomed creeks and small rivers. It is often found among debris and undercut banks. It is found in bodies with reduced current, usually under overhanging banks or overhanging vegetation, or around roots or stumps.
