Dorsal spines (total): 8; Dorsal soft rays (total): 9; Anal spines: 2; Anal soft rays: 8. Distinguished by having the following characteristics: dorsal fin rays VII-I, 9; anal fin rays II, 8; pectoral fin rays 15; pelvic fin rays I, 5; pored lateral line scales 24; predorsal scales 3; circumpeduncular scales 12; body pinkish brown, with four dark brown stripes on lateral surface of body; third stripe posteriorly not reaching to a black spot on caudal fin base; caudal fin base spot subequal in size to pupil diameter (Ref. 93839).
Commonly occurs in rocky areas near shore and abundant on ledges. Solitary but pair off during breeding. Mouth brooding is done by the male. Nocturnal species (Ref. 7300).
Mouthbrooders (Ref. 240). Distinct pairing during courtship and spawning (Ref. 205).

Estimates based on models
Preferred temperature (Ref.
123201): 20 - 28.9, mean 27.6 °C (based on 1621 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01413 (0.00807 - 0.02472), b=3.17 (3.02 - 3.32), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.56 se; based on food items.
Generation time: 0.5 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
