Breeding males are brassy yellow, bright red along lower side (Ref. 86798).

Adults inhabit runs and flowing to standing pools of headwaters, creeks, and small to medium rivers as well as lakes and ponds. Usually found over mud or sand, often near vegetation (Ref. 5723, 86798). They form schools (Ref. 1998). Fry feed on diatoms, copepods, ostracods, and other small planktonic and demersal crustaceans (Ref. 1998). Diet changes to terrestrial and aquatic insects, algae, mollusks, fish eggs (including their own), and small fishes like other redside shiners, other minnows, and trout (Ref. 1998). Preyed upon by mergansers, loons, and mink (Ref. 1998).
