Length at first maturity / Size / Weight / Age
Maturity: Lm 7.4  range ? - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 86798); common length : 8.3 cm TL male/unsexed; (Ref. 12193); max. reported age: 6 years (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).
