The brassy minnow, Hybognathus hankinsoni, is native to southern Canada and much of the northern United States, but it is not native to Utah. The species has, however, been introduced to Utah and now occurs in the Colorado River system.
The brassy minnow is an opportunistic feeder, eating such items as algae, phytoplankton, zooplankton, insect larvae, and other small invertebrates. The species spawns in the spring, and eggs hatch in about one week. The brassy minnow is a schooling species that is often found in sluggish waters and flooded areas containing vegetation.
