Amphiprion polymnus
An anemonefish with a dark body, a white head bar and a saddle-shaped white patch on the back, and as the Japanese name suggests a reddish head. It lives with Haddon's carpet anemone on silty inshore bottoms and occurs in the Ryukyu Islands.
The Saddleback Clownfish (Amphiprion polymnus) ranges across the western Pacific from the Ryukyu Islands to Taiwan, the Gulf of Thailand, Indonesia, the Philippines, northern Australia and the Solomon Islands. Unlike most clownfish it inhabits silty lagoons and harbors at 2-30 m, living mainly with Haddon's carpet anemone (Stichodactyla haddoni) and the leathery anemone (Heteractis crispa). The dark brown to orange-brown body has a white head bar, a saddle-like white patch on the back and a white edge on the tail; the reddish head gives the Japanese name. Maximum length is 13 cm. It is a protandrous hermaphrodite that spawns in pairs on the substrate, with the male guarding the eggs. It has been reared in captivity and captive-bred fish are traded. It is hardy and easy to keep; a tank of 114 L or more is recommended. A host anemone is optional, but a tank with open sand shows its natural behavior. Keep one pair, as several clownfish of the same or different species fight over territory.
