The warpaint shiner (Luxilus coccogenis) is a species of freshwater fish found in North America. It is common in the upper Tennessee River basin as well as in the Savannah River, the Santee River, and the New River in North Carolina. Adults have a mean length of 9 centimetres (3.5 in) and can reach a maximum length of 14 centimetres (5.5 in). The maximum age reported for this species is 4 years. Warpaint shiners live in cool streams with gravel and rubble beds. They feed on aquatic insect larvae and on terrestrial insects they catch on the water surface. The warpaint shiner provides forage for sport fish such as small and large mouth bass. Importantly the warpaint shiner acts as host to the federally endangered freshwater mussels known as heelsplitters.
