Another fish

I have a purple tang which is beating the crap out of both the yellow fish. The purple tang has been in the tank for only two days.

Should I remove the yellows or should I give little more time to see is they get along?

We need a bit more info, like what's the tank size? I see you have at least 4 tangs?

I have a naso, blond naso, desjardini, hippo. All of them are quite peaceful

I had both yellow tangs for a long time
Decided to introduce a purple. I knew that the yellows won't like him. So pulled yellows out of the tank for couple of days before returning them back together. The purple is very fiesty. The attack has subsided today but didn't completely stop. Worried they may catch ich.

Looks like a battle wound from a scalpel

Can something be done about it? Should I pull him out of the tank?

I would probably take out the aggressor and you might want to think about a quarantine situation with copper to kill off the Ick.
