Description

The rosyside dace is a slender cyprinid of the family Leuciscidae reaching about 12 cm. The silvery body has a fairly large, oblique mouth; in the breeding season the male's flank turns vivid red, with red fin bases, from which the species takes its name. The species is native to the fresh water of eastern North America and lives in schools in clear, cool, flowing streams with gravel bottoms. Just below the surface and in the water column it hunts drifting and suspended insects and small invertebrates. In spring it spawns on gravel bars, often over the nest pits of other cyprinids. It is a sensitive indicator of clean, cool stream water and an important prey fish.
