Acapulco Major

Found singly or in pairs, over shallow waters of rocky reefs. Very territorial.
They feed on turfed algae which they guard and farm.

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.
