The Rosefin shiner (Lythrurus ardens) is a freshwater fish of the family Cyprinidae that grows up to 9 cm.
Description
The rosefin shiner is a slender cyprinid of the family Leuciscidae reaching about 9 cm. Outside the breeding season it is inconspicuously silvery, but the breeding male turns steel-blue with red-orange fins and develops tubercles on the head, from which the species takes its name. The species is native to the fresh water of the eastern USA and lives in schools in clear, flowing rivers and streams with gravel bottoms. It eats drifting insects, zooplankton and algae, taken in the water column and at the surface. In spring and summer it spawns on gravel bars, often over the nest pits of other cyprinids. Through its great numbers it is an important prey fish.
