Adults are usually associated with the corals Stylophora pistillata, Stylophora wehisi, species of Acropora and Porites. Monogamous (Ref. 52884). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
Life cycle and mating behavior

Benthic spawner. Oviparous, distinct pairing during breeding (Ref. 205). Monogamous mating is observed as both facultative and social (Ref. 52884). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). While protogyny was originally proposed for this species, recent studies confirmed gonochorism in the form of non-functional hermaphroditism (Ref. 103751).
