Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 7.4 range ? - ? cm
Max length : 18.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 86798); common length : 8.3 cm TL 雄鱼/尚未辨别雌雄; (Ref. 12193); 最大年龄: 6 年 (Ref. 72462)
Inhabits rocky pools near riffles in clear, cool creeks and small to medium rivers. Sometimes occurs in lakes in northern part of range (Ref. 86798). Oviparous (Ref. 205), nest spawners (Ref. 52559). Frequently hybridizes with Luxilus chrysocephalus in areas where the ranges of these two species overlap (Ref. 86798).
在清澈寒冷的小溪及小型到中型河川中的急流附近栖息于岩石的水池。 有时在范围的北部中出现于湖中。 在 Luxilus cornutus 与 Luxilus chrysocephalus 之间的杂交时常在两者种的范围重叠的区域中出现。
