Overview

Found singly or in small schools, close to the shelter of thickly branching corals, over lagoons and fringing reefs rich in coral growth.

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.
