Amphiprion ocellaris

The ocellaris clownfish — star of Finding Nemo — is the most popular saltwater aquarium fish and one of the best choices for beginner reef keepers. Captive-bred specimens are hardy, readily available, and don't require an anemone host (though they will happily adopt one). They are one of the few marine fish that breed regularly in home aquariums.
