Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; depth range 3 - 40 m (Ref. 9710). Tropical; - 30°S
Western Indian Ocean: East Africa south to Durban, South Africa (Ref. 5372). Also found in oceanic islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm TL male/unsexed; (Ref. 9710)
Usually seen alone or in pairs (specially during spawning) but occasionally in small groups, particularly in the vicinity of staghorn Acropora and Goniopora (Ref. 5503) thickets. Diet consists of live corals which makes it difficult to maintain in captivity (Ref. 4858). Little intraspecific nor interspecific aggressiveness (Ref. 5503). Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205).

Distinct pairing (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).
