I suggest you do a search on pictures of Psych Head Wrasse, you'll then see this is a Psych Head Wrasse.
It might possibly be that, but still need a better pic of it, if the red in the tail is gone the orange in the face should be there by now and the spots on the face should be larger by now, it doesn't resemble the male I had. Mine didn't look like that during the change, but like I said a better pic would help or should I say a better colored up pic. How much did you pay for it?
