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: Freshwater Fishes of the Carolinas, Virginia, Maryland, & Delaware)
