White spot under carpenter wrasse dorsal fin

[Bassman85]

Hello everybody, this is my first time posting. I need some help with identifying this white spot on my carpenter wrasse dorals fin. I just got him Wednesday night along with a melanarus wrasse and midas blenny. They are all in a quarantine tank. I figured that I would keep them under observation for the next several weeks and if any signs of illness show up start the proper treatment. I just wanted to get your thoughts and opinions on what the white spot could possibly be. I haven’t noticed any signs of it growing. I have not seen any signs of illness on any of the fish. No spots or flashing just the occasional yawn. Thanks for any help much appreciated.

I forgot to mention that the white spot has been there since I first got him.

it looks like injury. Should heal without problem.
