Description

The mountain redbelly dace is a small cyprinid of the family Leuciscidae reaching about 7 cm. Two dark lengthwise stripes run along the flank over a golden-yellow ground. In the breeding season males colour spectacularly: the belly turns bright red and the fins and flanks yellow, one of the finest colour displays among North American stream fishes. The species lives in schools in clear, cool streams and small rivers with gravel in the eastern Appalachian region. As an omnivore it eats algae, diatoms, small invertebrates and detritus. In late spring it spawns over gravel, often on the nests of other minnows. Because of its colour it is sought after by keepers of native aquarium fish.
