Marginate Dascyllus

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).
