Can anyone ID whats wrong with my wrasse

[Eric23]

I have a carpentars wrasse and a few days ago i noticed a little white spot on his head that looked like either someone talk a little nip at him or he got cut on rock. A few days later its looking worse and seems to be spreading. Im not sure what to do or what it is ????

What else fish wise is in your tank?

 

[Eric23]

Melanurus wrasse, percula, neon dotty, and niger trigger

 

[Eric23]

Trigger is tiny maybe 3 inches

I havent noticed any aggression in any of the fish and i spend a lot of time looking at my tank. That said my dottyback is an A Hole and has killed off a few fish

If it is a bite/cut that has gotten infected, it would be best to treat in a QT using Kanaplex. You can add Furan-2 and even Metroplex to the mix if kanamycin doesn't get the job done.

Watch out for the neon Dottyback and Niger. They are very aggressive. If their not now they will be. Just a fyi

It certainly looks like an injury and the dottyback and trigger are top of the suspect list.
