Occur in coral rich areas of clear lagoon and seaward reefs, and feed exclusively on coral polyps (Ref. 9710). Juvenile usually solitary among branching corals, adults usually paired and home-ranging (Ref. 9710, 48636). 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).
