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).
棲息於快速的礫石小支流, 有時急流, 小溪及小型到中型河川。 時常在灌木的附近發現。 (參考文獻 5723,10294) 稚魚吃蚊與黑蠅幼生; 成魚消費 caddisfly 與孚游類仔魚。 (參考文獻 10294)
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).北美洲: 密西西比河流域從俄亥俄州與西維吉尼亞到伊利諾州東部而且南至在美國的路易斯安那; 從在阿拉巴馬州的黑武士河到哥德洛普島河在美國德州的海灣流域。
