Nope its not a clown wrasse, just by looking at the fins, you can clearly see its a juvenile bluehead wrasse.
This is a male adult bluehead.
They are hermaphrodites, and hard to care for if no sufficient space. He MIGHT stay like that until you find another one, then he becomes the colorful bluehead(first image). If you get another one it will change its sex to female and its color to this (the first one you got will change the color according to the first image):
This is a female bluehead.
There are TONS of them over here in Puerto Rico, they are cool and colorful but definitely not worth it.
