Fusilier Damselfish

Found in small to large schools, over current swept patch reefs, of lagoons and seaward reefs. Variable in colour, changing when feeding and disturbed.
They feed high above the reef on zooplankton.

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.
