Blackbar Devil

Found singly or in pairs, sheltering in the arms of staghorn corals, over clear water surge zones of lagoons and seaward reefs rich in coral growth.
Adults have a yellow tail and juveniles a white tail.

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.
