False clown anemonefish (Amphiprion ocellaris) in its host anemone. Anemonefish have a symbiotic relationship with their host anemones. They are protected from predators by the stinging tentacles of the anemones (to which they are immune), and the fish clean the anemones by feeding on small parasitic plants and animals. Photographed at Misool, Raja Empat, West Papua, Indonesia.
