Description

The Acapulco damselfish is a damselfish (Pomacentridae) from the eastern Pacific. The species has a deep, laterally compressed, dull-brown body; juveniles are more brightly coloured. Adults inhabit rocky inshore reefs, where they fiercely defend a territorial 'algal garden' against intruders. As a territorial herbivore it grazes mainly the filamentous algae farmed within its territory and fiercely chases off intruders, even much larger fishes. The species is harmless to humans.
