Clown Anemonefishカクレクマノミ
Amphiprion ocellarisLC— Least Concern
The ocellaris clownfish, often simply called the clownfish, is a small orange-and-white reef fish famous for its symbiotic partnership with sea anemones, whose stinging tentacles it is immune to. Native to the eastern Indian Ocean and western Pacific including Japan, it lives in strict size-based social groups where the largest fish is always female, and captive-bred individuals can live well over a decade.
