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. Ref: https://www.fishbase.se/summary/5725
