Maturity: Lm ? range ? - ? cm
Max length : 14.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 86798); common length : 8.9 cm TL 雄魚/尚未辨別雌雄; (Ref. 12193); 最大年齡: 4 年 (Ref. 12193)
Inhabits gravel and rubble riffles and adjacent pools of clear, fast creeks and small to medium rivers (Ref. 86798). Common in cool, clear streams with rocky substrates. Feed on mayfly nymphs and other aquatic immatures, with some terrestrial insects during spring, while summer food consists mostly of insects taken at the surface, with aquatic immatures (Ref. 10294). Oviparous (Ref. 205), probably nest spawners like congeners.
成魚棲息於礫石與清澈又快速小溪及小型到中型河川的碎石急流與毗連水池;(參考文獻 205) 常見於冷的, 清澈溪流有岩石的底部。 捕食孚游類蛹與其他的水生不成熟的, 有一些陸棲的昆蟲春天時, 然而夏天食物大部份採自表面的昆蟲組成, 具有水生的不成熟的.(參考文獻 10294) 卵生的 (參考文獻 205), 可能築巢像同類的產卵魚。 (參考文獻 5723)
