Description

The southern redbelly dace is a small cyprinid from the central and eastern United States. The species grows to about 9 cm and has a slender body with two dark lateral stripes; in the breeding season males turn brightly coloured with a red belly, to which the name refers. It inhabits rocky, often spring-fed pools of headwaters and creeks with clear, cool water. As an omnivore it grazes algae and diatoms from stones and eats small invertebrates. It is a peaceful schooling fish. Owing to its small size it is mainly prey for larger fishes and is harmless to humans.
