Adults occur in small communities. Usually found over rocks either solitary or in aggregation (Ref. 86760). Feed by scraping rock biocover (Ref. 6770). Females brood their young in the mouth (Ref. 7248, 86760).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.0 se; based on diet studies.

Resilienza (Ref. 120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (11 of 100).

Price category (Ref. 80766): Unknown.
