Saddleback Clownfish

"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. In some varieties, typically those specimens initially associated with H. crispa anemone, the saddle shape may extend up onto the fish's Dorsal fin with a third white bar or margin located across the caudal peduncle."
