Morphology | Morphometrics
soft rays: 12 - 13. This species is distinguished by the following set of characters: D IX,18-20; A II,12-13; pectoral rays 17-18; tubed lateral line scales 33-48; gill rakers 5-6 + 11-12; opercular spinules 8-11; body depth 2.2-2.6 in SL; color generally pinkish brown, usually grading to yellowish or orange on lower side of body including abdomen; white stripe on midline of snout extending posteriorly on forehead and along base of dorsal fin; fins whitish to semi-translucent (Ref. 85605).
This species is generally commensal with the anemone Heteractis magnificus (Quoy & Gaimard, 1833) at depths between about 4-10 m (Ref. 85065). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
