Yellowtail anemonefish (Amphiprion clarkii). This anemonefish has a symbiotic relationship with many anemones. It is protected from predators by the stinging tentacles of the anemones (to which it is immune), and the fish cleans the anemones by feeding on small parasitic plants and animals. It is found on reefs in the tropical Indo-West Pacific region, and can reach a length of 15 centimetres. Photographed in Kimbe Bay, Papua New Guinea.
