Black-banded Demoiselle

Found singly or in small schools, over silty, sandy bottoms, close to rocks, rubble, and sponges, of lagoons and coastal reefs.
Juveniles often found hiding in sea anemones.

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.
