01

Overview

Found in pairs, family groups, and large schools, sheltering in the arms of staghorn corals, over lagoons, coral, and rocky reefs. Geographical colour variations.

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.
