The creek chub, Semotilus atromaculatus, is a nonnative minnow that is rare in the upper Colorado River system of Utah. The creek chub is native to much of the central and eastern United States, as well as to much of southern Canada.

The creek chub feeds opportunistically on both plants and animals, including small fishes, but the majority of its diet is composed of invertebrates. The species spawns in late spring and summer; males build nests and guard the eggs until they hatch, which usually takes about six days. The creek chub is a schooling species that prefers to occupy small slow-moving streams.
