Amphiprion clarkii
A hardy anemonefish with a dark brown to black body, two or three white bars and a white to yellow tail. It occurs in Japanese waters, accepts the widest range of host anemones of any clownfish, and is easy to keep.
Clark's Anemonefish (Amphiprion clarkii) has the widest range of any anemonefish, from the Persian Gulf to Western Australia, Indonesia, Melanesia and Micronesia, and north to Taiwan, southern Japan and the Ryukyu Islands. It lives in lagoons and on outer reef slopes at 1-70 m. The body is dark brown to black with white bars and a white to yellow tail, and coloration varies greatly by region and host; juveniles are yellow with three white bars. It reaches 15 cm SL and a maximum reported age of 11 years. FishBase records it with ten species of host anemone, the least host-specific of all clownfish. Pairs spawn on the substrate and the male guards and aerates the eggs. It is hardy and tolerant of water quality changes, so care is easy: a tank of 114 L or more is recommended and no anemone is needed. It is somewhat aggressive toward other clownfish and passive fish and will chase anything other than its mate once grown, so keep several only in large tanks. Captive-bred fish are available.
