Inhabit fast gravel runs, sometimes riffles, of creeks and small to medium rivers. Often found near brush (Ref. 5723, 10294). Young are found in shallower gravel riffles (Ref. 7043). Juveniles feed on midge and blackfly larvae; adults consume caddisfly and mayfly larvae (Ref. 10294). Males are larger and darker in color during breeding (Ref. 69400).
While in captivity, males exhibit tail-beating while infront of a large female aside from color changes as prespawning behavior (Ref. 69400). 'The generalized condition of a midventral row of specialized scales suggests that the male mounts the female and aligns his body with hers during fertilization and deposition of the eggs' (Ref. 69400).
