Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 13; Dorsal soft rays (total): 11 - 12; Anal spines: 2; Anal soft rays: 11 - 12; Vertebrae: 26. Diagnosis: Ventral edge of the suborbital scaled over. Dorsal and anal soft rays usually 11; pectoral usually 18. Tubed lateral line scales modally 17; gill rakers 20-23, usually 21-22. Body depth 2.4-2.95 in SL. Caudal fin and posterior part of dorsal fin yellow; anal fin mainly yellow without small blue spots; pectoral fin axil with a black spot, continuing as a prominent wedge shaped spot above the fin base; a black spot covering all but ventral part of pectoral fin base. There is a black spot as large or larger than pupil over first lateral line scale (Ref. 57550).
Collected and observed on coral reefs or rocky bottom (Ref. 57550). Life history characteristics for the family specify that this group is oviparous, with distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
