Most abundant in creeks and small rivers with gravelly or rocky bottoms and strong, permanent flow. Usually found in protected backwaters near riffles or in pools directly below riffles. Often seen in large schools with other common minnows such as bleeding, cardinal, and duskystripe shiners.

One of the most common minnow species in the Ozark uplands.

Life cycle

Usually only live for about three years. Most active in daytime. Ozark minnows spawn late April to early July. Spawning activity peaks in May and June. Like the bleeding shiner, Ozark minnows often spawn over nests of the hornyhead chub. The Ozark minnow and bleeding shiner frequently spawn at the same time and place, and hybrids between them are common.
