Bumps on Swallowtail Angel

[Macimage]

I have a swallowtail angel in qt with bumps on her side. She has been in copper power for 1 week. Should I do a water change and switch to prazi pro? Also, I have a hybrid tang and another swallowtail in with her. Is this contagious? They have been together since Feb. 8th.

These look like marks from post injury/puncture. Do you have Urchins or anemones? Other would be bite marks, something clowns would do or tail strikes from a tang.
What fish do you have in the tank with it and have you noticed any chasing or aggression.
This may or may not subside and be prepared to treat in a separate tank with seachem neoplex
In tank would be ruby rally pro

She is in a 45 gallon with a hybrid Tang that hides most of the time. However, the other swallowtail does chase her.
She also spends some time at the surface for air even with a bubbler and loc line agitating the surface.
Can I add ruby rally pro with the copper power?
