Adults inhabit rocky riffles and adjacent pools of headwaters and creeks (Ref. 86798). Herbivorous, bottom feeder (Contreras-Balderas 1974) feeding mainly on diatoms, bacteria and algae (Ref. 79012). Migratory behaviour is undetermined (Ref. 126106).
栖息于河源上游与小溪的岩石急流与毗连水池。

Adult males construct spawning pits by digging into the gravel with their snouts or mouths and remove small pieces of substrate (Ref. 51088, 31216). Mating occurs in the pits afterwhich the eggs are abandoned (Ref. 51087). Males are highly territorial (Ref. 51087). In other occasions, Campostoma species spawn in nests of Nocomis and Semotilus and with each other as nest associates (Ref. 51087).
