Abstract

Clown fishes of the genus Amphiprion are a valuable resource from the point of view of the aquarium trade. There are about 27 species distributed widely in the Indo West Pacific region, extending from the eastern Indian Ocean to the Indonesian and Philippine archipelagos and from the coast of northwestern Australia to the Ryukyu Islands of Japan (Allen 1980; Fautin & Allen 1992). Allen (1991) used morphological similarities to designate six taxonomic complexes of closely related species. Apart from colour variation, tooth shape, scalation on the head and body proportions are used to identify the species of clown fish (Fautin & Allen1992).The occurrence of multiple colour variants in most of the species, besides variations in colour patterns between juveniles and adults of the same species, makes unambiguous identification in clown fishes difficult.
