Blueline Demoiselle

Found in small schools, over rock, and rubble areas, of sand channels, and steep outer reef slopes, rich in algae and 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.
