Onespot Demoiselle

Found singly or in small schools, in moderate, very shallow, surge zones, over reef flats, rocky beaches, and rubble areas, rich in algae growth. Very territorial.

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.
