Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 9710); common length : 16.0 cm TL male/unsexed; (Ref. 48636)
Occur in small groups in reef flats, clear lagoon and seaward reefs (Ref. 48636). Benthopelagic (Ref. 58302). Feed on soft and hard corals, also on polychaetes, small crustaceans, and filamentous algae. In Indonesia, usually seen at moderate depths, usually swimming in small groups. Adults are mainly in depth 20-60 m (Ref. 48636). Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Distinct pairing (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).
