臀鳍软条: 9 - 10. Anal fin with 9-10 rays; ventral-fin origin before dorsal-fin origin; large, forked caudal fin; pharyngeal teeth 1,5-4,1; scales absent; wide, flat head; body compressed at rear; subterminal mouth on long, rounded snout; barbel at corner of mouth; fairly small eye high on head; dusky gray above; brilliant silver side, often with blue sheen, sometimes faint yellow at paired fin bases; breeding males with pink lower side (Ref. 86798).
Occurs in fast sandy runs and pools of small to medium rivers, usually in warm turbid water (Ref. 86798). Most commonly found in shallow, moderately flowing water over shifting sand substrates (Ref. 26186). Spawning in the Virgin river begins in April to May and continues through August (Ref. 26186).
栖息于小型到中型河的快速多沙的支流, 通常在温暖的浑浊水。 有时在水池中.(参考文献 5723) 改变沙子底部之上最普遍发现于浅且流动和缓的水。 (参考文献 26186) 产卵在处女河中在四月到五月开始而且继续过八月。 (参考文献 26186)
