Maturity: Lm ?  range ? - ? cm
Max length : 11.0 cm TL male/unsexed; (Ref. 2798)
soft rays: 8. Characterized by mottled brown overall color; presence of broad dark grey bar below each dorsal fin; basal part of dorsal and caudal fins with dark spots forming bands; upper 5-7 pectoral rays partly free of membrane, uppermost with 5-7 branches; rounded caudal fin; longitudinal scale series 35-39; predorsal scales 21-23, extending to interorbital space; presence of scales on cheek and opercle; ctenoid body scales, becoming smaller and cycloid on head and anterior body; depressed head, width greater than depth; depth of body 4.2-5.0 in SL (Ref. 90102).
Benthic in rocks and coral of shallow waters (Ref. 58302). Also occurs in rocky pools of intertidal reef flats and exposed rocky shores in 0-2 m (Ref. 90102).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.9 - 29.3, mean 28.2 °C (based on 2181 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00475 - 0.02204), b=3.03 (2.85 - 3.21), 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
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (22 of 100) .
