Maturity: L_m 7.4 range ? - ? cm
Max length : 18.0 cm TL Männchen/unbestimmt; (Ref. 86798); common length : 8.3 cm TL Männchen/unbestimmt; (Ref. 12193); max. veröff. Alter: 6 Jahre (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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00871 (0.00449 - 0.01691), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±0.2 se; based on diet studies.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (tm=1; tmax=4).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
