Overview

Found in large schools, hiding in the arms of dead and living staghorn corals, over clear-waters of channels, lagoons, and seaward reef slopes.
This fish differs from the Blue-green Chromis-Chromis viridis, because it has a black spot at the base of the pectoral fin.

Damselfish are egg layers.
First they clear a site ready for a nest, then engage in a mating dance with rapid swimming and fin movements, during this time the males will often turn a shade or two darker and may display white blotches. Spawning occurs at dawn.
