Pigmentation: For both males and females, sides are yellow-gold, dorsal surfaces are olive in color, and caudal fins are bright red on the outside and becoming orange at the center.
顏色： 對於雄性和雌性，側邊是黃色的-黃金, 背面是橄欖色顏色，而且尾鰭在外面上是鮮紅色而且在中心變成橘色。
Occurs in sandy to rocky pools and runs of medium to large rivers, and also in lakes. Spawning occurs along edges and midstream areas of riffles, on pebble, cobble, and gravel substrates (Ref. 49090).
出現於中型到大型河川的砂質或岩質水潭與急流, 以及在湖中。 在小圓石，圓石與礫石底部上,產卵沿著急流的邊緣與中央。 (參考文獻 49090)
Spawn in groups with between two and seven males and one or two females. Males pose on other side of a female prior to spawning. Brisk vibrations of the dorsal and caudal fins occur during spawning. Gametes are released while males and females rolled over one another. Mean duration of spawning event is 4.4 seconds +/- 0.5 s. Mean duration between spawning events is 22.2 +/- 5.3 mins (Ref. 49090).北美洲: 五大湖- 聖勞倫斯的河, 哈得遜灣 (在紅河) 與密西西比河流域從加拿大魁北克與佛蒙特州在美國到南方的加拿大安大略省與北方的明尼蘇達州, 而且在肯塔基州，美國南至俄亥俄河。
