Fox face sting or ich?

[Dev795]

So yesterday i watched my foxface and hippo tang chase each other around the tank(they have been together and fine for three months), while the foxface had its spines out. Today I’ve seen a few white spots on the hippo tang. Could it be ich? Maybe stung by the fox face??? I haven’t added anything to the tank in three months and go through a qt before adding anything to the dt
I’ll try and get some photos and post them
What do you think?

Definitely pics would help. I have heard of Foxface stings killing other fish or causing discoloration but personally never white spots.

Qt and treat with coppersafe. Assure adequate oxygen .

Looks like a wound, bacterial infection And velvet to me.

So i have had the hippo tang along with the other fish i have in a qt tank running copper keeping it at the .5
It seemed to have resolved it self with medication but now it’s back on the fin on one side, today is two weeks, i know there are stages of ich i am still learning but how much longer should i keep treating with copper? All other fish are doing fine with no return as of yet

Thanks!
