Thai Damsel

Found singly, or in small schools, over coral reefs, in lagoons and over coastal shorelines.
Eastern Indian Ocean - Andaman Sea

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.
