Short description

Dorsal spines (total): 17; Dorsal soft rays (total): 14 - 16; Anal spines: 2; Anal soft rays: 14 - 16. Color pattern variable, ranging from entirely blackish to uniform pale gray.

Inhabits inshore and offshore coral reefs (Ref. 9710). Also found in harbors, lagoons and outer reef slopes. The only pomacentrid species that lacks a pelagic larval stage. One of the very few marine fishes where fry are guarded by the parents (Ref. 9710, 48636). School as they grow and sub-adults are usually seen in small groups. Adults form pairs and are territorial when breeding (Ref. 48636). Monogamous (Ref. 52884).
