Panamic Sergeant Major

Found in large schools, swimming above coral and rocky reefs.
They feed during the day, on the surface or mid-water, on filamentous algae and benthic invertebrates.

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.
