Johnston Damsel

Found singly, or in small, loose schools, sheltering in the arms of Acropora and Pocillopora corals, over clear water inner and outer reef crests and slopes 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.
