Black anemone fish (Amphiprion melanopus) hidden in the tentacles of a partially bleached sea anemone. This fish, also known as the fire clownfish, is found on the coral reefs of the tropical Pacific Ocean. The anemone fish has a symbiotic relationship with the sea anemone. The sea anemone provides the anemone fish a safe haven by protecting it from predators through its stinging tentacles. The fish is immune to the sting and cleans the anemone by feeding on parasites such as algae and zooplankton. Photographed in Milne Bay, off Papua New Guinea.
