Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 1 - 60 m (Ref. 89972). Tropical; 30°N - 20°S
Indo-Pacific: Red Sea and East Africa (extending to Mossel Bay, South Africa, Ref. 5372) to the Hawaiian, Marquesan, and Ducie islands, north to southern Japan, south to Lord Howe and Rapa islands.
Length at first maturity / Size / Weight / Age
Maturity: Lm 13.0  range ? - ? cm
Max length : 23.0 cm TL male/unsexed; (Ref. 4859)
May be seen in a variety of habitats ranging from rich coral reefs (Ref. 58652) to weedy and rubble covered areas (Ref. 1602). Benthopelagic (Ref. 58302). Maybe found singly, in pairs, and in aggregations that roam over large distances in search of food. Feed mainly by tearing pieces from polychaetes, sea anemones, coral polyps, and algae (Ref. 1602). Oviparous (Ref. 205). 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).
