   The keels on the caudal peduncle are larger in males than in females and the males also have longer filaments growing from the caudal fin. The overall colour is grey, with a dark snout separated from the grey head by a yellow bar at the eyes. The dorsal fin is yellow with a thin blue edge and a black band inside that. The anal and pelvic fins are dark brown. The plates on the caudal peduncle are vivid orange separated by a patch of white.
