Commonly found on reef flats (Ref. 9710). Usually solitary or in pairs in areas with rich coral growth. Monogamous (Ref. 52884). Feed mainly on coral polyps (Ref. 4858). 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).
