Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 5723); common length : 12.2 cm TL male/unsexed; (Ref. 12193); max. reported age: 4 years (Ref. 12193)
Inhabit clear, fairly deep, rocky pools (usually below riffles) of creeks and small rivers. Large males often found in rocky riffles (Ref. 5723). Juveniles feed on mayfly and dipteran larvae, while the adults consume caddisfly larvae (Ref. 10294). Eggs are found buried in the substrate (Ref. 7043).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00235 - 0.01227), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (tmax=4; Fec=750).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
