Family

Cyprinidae (minnows) in the order Cypriniformes (carps, minnows and loaches)

Description

Dark stripe along midside extending from nose to tail; an iridescent greenish-brown back with a narrow, lighter-colored band above the lateral dark stripe; silvery-white lower side and belly. Breeding males have bright red fins, cheeks, and underside of head and body. Tip of snout is blue. Similar in appearance to bleeding and cardinal shiners, but the ranges for these species do not overlap with the duskystripe shiner.

Size

Total length: 3 1/2 to 4 1/2 inches; maximum about 4 3/4 inches.

Habitat and conservation

Typically found in stream pools in mixed-species schools with a number of other minnows. Most commonly found in Ozark headwater streams with swift riffles and pools with clean gravel bottoms. Unlike the similar cardinal shiner, this species can be found in headwater streams.

Foods

Aquatic and terrestrial insects. Researchers have also found in the stomachs of this species algae, leafy and woody material and seeds from land plants.

Distribution in Missouri

In Missouri, only found in the White River system of southwest and south-central Missouri.

Life cycle

Few live beyond four years. Peak activity is at dawn and dusk. Spawns over the gravel depressions around the mound nests of hornyhead chubs, usually in close association with another minnow species: southern redbelly dace, Ozark minnow and rosyface shiner. Sometimes hybridizes with those species.
