Description
The redside shiner is a cyprinid from western North America. The species grows to about 18 cm and has a slender, laterally compressed body with a dark back, silvery flanks and, in spawning individuals, a reddish tinge along the side, to which the name refers. It inhabits flowing and standing pools of headwaters, creeks, rivers and lakes. As an omnivore it feeds on insects, small zooplankton, algae, fish eggs and small invertebrates.
