About Clown triggers:
Young specimens have large white spots over most of the body and head. The snout is yellow and the fins are pale colored. As the fish grows, a yellow saddle begins to show around the dorsal fin, and this becomes covered in small bluish-black spots. The yellow on the snout recedes to an area around the mouth and this bordered with a yellowish-white line.
