Bluntsnout Gregory

Found singly, or in pairs, defending their territory, amongst the branches of dead, staghorn coral patches, over very shallow areas, of coral reefs. Aggressive to other fish, taking "nips" from divers if too close! They emit a clicking sound during aggressive encounters.
Indian Ocean fish have an Ocellated spot.
They feed on filamentous algae from the bases of the dead coral they are defending.

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.
