Adults occur usually in shallow sandy runs and pools of creeks and small to large rivers (Ref. 86798). Oviparous, probably open substratum spawners like congeners (Ref. 205). Migratory behaviour is undetermined (Ref. 126106).

生命周期和交配行为 成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
The pelagic-broadcast spawning behavior consisted of males pursuing a single female and nudging her abdominal region. When the female was ready to spawn, a single male wrapped around the female at which time eggs and milt were simultaneously expelled. Reproduction usually consisted of several individual spawning episodes with at least 10-min intervals between events (Ref. 35784).北美洲: 密蘇里，阿肯色州，紅色，布拉索斯與科羅拉多河流域從蒙大納與達科塔北方部南至新墨西哥州與美國德州; 從密蘇里河口到俄亥俄河口的密西西比河。
