Habitat requirements and life history:
The creek chubsucker is a native species that inhabits clear,
slow-moving waters of streams, small rivers and lakes, usually
over a soft bottom with abundant vegetation. The creek chubsucker
feeds on small crustaceans, small insects, and algae. It spawns
in the spring, when adults migrate to small pools with a sand
or gravel substrate and a current. The creek chubsucker probably
spawns in groups, like the white sucker. (Source:
