Saddleback Clownfish (Amphiprion Polymnus)

Amphiprion polymnus, also known as the saddleback clownfish or yellowfin anemonefish, is a Marine fish belonging to the family Pomacentridae which gathers clownfishes and damselfishes. The Saddleback clownfish is a small sized fish which grows up to 13 centimetres (5.1 in). Its body has a stock appearance, oval shape, compressed laterally and with a round profile.[3]

Color ranges from dark brown to yellow orange with a thick white bar located just behind the eyes. A large white abbreviated saddle shape or slanted white bar across the middle of the fish's body makes it quite obvious to see how it got the name Saddleback.[4] In some varieties, typically those specimens initially associated with H. crispa anemone,[4] the saddle shape may extend up onto the fish's Dorsal fin with a third white bar or margin located across the caudal peduncle (pictured in taxobox).

Melanistic variation has also been partially correlated with the fish's host anemone. Specimens associated with H. crispa tend to be darker than those associated with S. haddoni. Aquarium specimens have been observed becoming lighter or darker after accepting a new host anemone species, sometimes within a few hours.[4] The external edge of the caudal and the anal fins are underlined with a white line. The snout and the pectoral fin are in any case of color variation orange yellow to brownish orange. (From Wikipedia)
