Amphiprion sandaracinos, also known as the orange skunk clownfish or orange anemonefish, is a species of anemonefish that is distinguished by its broad white stripe along the dorsal ridge. Like all anemonefishes it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host anemone. It is a sequential hermaphrodite with a strict sized based dominance hierarchy: the female is largest, the breeding male is second largest, and the male non-breeders get progressively smaller as the hierarchy descends. They exhibit protandry, meaning the breeding male will change to female if the sole breeding female dies, with the largest non-breeder becomes the breeding male.
A. sandaracinos is one of the smaller anemonefish, which grows up to 11 cm as a female and 3 to 6.5 cm as a male. Its body has a stock appearance, oval shape, compressed laterally and with a round profile. Its coloration is bright orange, with a white stripe on the dorsal ridge from the superior lip, passing between the eyes and ending at the caudal fin base. All the fins have the same coloration as the body except the dorsal fin which is partially white. Its iris is bright yellow.
A. sandaracinos is found in the center of the Indo-Pacific area, known as the Coral Triangle, from the Philippines to Indonesia and New Guinea.It is also found in north western Australia, Christmas Island, Melanesia and to the Ryukyu Islands of southern Japan.A. sandaracinos typically lives in small groups on outer reef slopes or in lagoons at a maximal depth of 20 metres (66 ft).
