Marine; reef-associated; depth range 3 - 30 m (Ref. 9710). Tropical; 36°N - 32°S, 47°E - 173°W
Indo-Pacific: Indonesia to Japan and south to the Great Barrier Reef and Papua New Guinea. Reported from Mauritius, Madagascar, and Reunion (Ref. 4858).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.0 cm TL male/unsexed; (Ref. 9710)
In coastal reef slopes rich with hydroids and anemones. Small juveniles secretive in coral thickets (Ref. 48636). Usually solitary and relatively uncommon. Feed on coral polyps and invertebrates (Ref. 9710). 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).
