The skunk clownfish is identified by a light orange color, with a single, narrow, white stripe running from the mouth to the caudal peduncle, and can grow as large as 11 cm in length.

[1] Like other anemonefish, the skunk clownfish is a protandrous hermaphrodite, and maintains a hierarchy within the host anemone that consists of a mating pair, of which the female is the largest, and non-mating males which get progressively smaller in size.

A. akallopisos does not have a melanistic variation when associated with Stichodactyla mertensii unlike some other species of anemonefish, including A. chrysogaster, A. chrysopterus, A. clarkii and A.

[7][8] Studies have shown that it is the female that defends the anemone using sound production, as well as a physical charge when other fishes attempt to enter.

[2] A. akallopisos is found in the Indian Ocean from Java and the Java Sea, western and southern coasts of Sumatra, the west coast of Thailand and north to the Andaman Islands west to Madagascar, Comoro Islands and Seychelles.
