White back anemonefish (Amphiprion akallopisos )

The white-backed anemonefish ( Amphiprion akallopisos ) lives in the coral reefs of the western and the eastern Indian Ocean. It has there two disjoint distribution areas, in the western Indian Ocean along the African coast of Mozambique to the tip of the Horn of Africa, in Madagascar, the Comoros and the Seychelles, as well as Indian in the eastern ocean in the Andaman Sea, in Sumatra, in the Java Sea and on the coast of southwestern Thailand. It is missing in the central Indian Ocean in Sri Lanka and the Maldives.

Features

The body, anal and pectoral fins are orange. Dorsal and caudal fin are white. A white streak starts at the snout and runs along the base of the dorsal fin to the caudal fin. The dorsal fin has eight to nine hard and 17 to 20 soft rays, the anal fin two hard and twelve to 14 soft rays. Amphiprion akallopisos becomes up to eleven inches.

He is very similar to the orange clownfish ( Amphiprion sandaracinos ) and differs from it by the different number of spines, the white tail fin, which is the orange clownfish oranges, as well as the narrower on the head white vertical stripes. The teeth of the white-backed anemonefish are designed as incisors, while the more of Amphiprion sandaracinos a conical shape. In the wild, both species can be confused only on the coasts of Java and the southeast of Sumatra, since the distribution areas overlap only there.
