These famous fishes make their home in sheltered lagoons and reefs within the Indian and Pacific Oceans. They range in size from 7-17 cm, and live inside anemones to protect them from larger, predatory fish. This fascinating symbiotic relationship benefits both species. In return for protection, the clownfish's bright colours lure other fish into the anemone, which stings and eats them. This is only possible due to the clownfish's thick mucous coat, which protects it from the anemone's stingers.
