Description

The redfin shiner is a small cyprinid from the central and eastern United States. The species grows to about 9 cm and has a slender, silvery-bluish body; breeding males develop reddish fins and a steel-blue sheen. It inhabits quiet to flowing, often turbid pools of headwaters, creeks and small rivers. As an omnivore it feeds on insects, small invertebrates, algae and detritus. It is an active schooling fish that often lays its eggs at the nests of sunfishes. Owing to its small size the species is harmless to humans.
