Help identifying wrasse ailment

[blurry]

I have 4 fish in copper treatment with a week to go. First time qt-omg, lots to learn!

the cleaner wrasse is developing some spots. Earlier last week I noticed a whitish general discoloration on third of the fish.

Now he has spots developing on the top fin and predominantly on the left side.

thoughts on what this might be?

thanks!

What other fish are in with it? Looks like bite marks to me.

Thank you for the responses. It’s a 20 gallon qt with a yellow assessor, small fox face, and a clownfish. I wasn’t expecting hostility with this crowd, guess you never know!

mid it safe to use maracyn two with copper power. Hanna is reading about 1.8 on copper. Fish are doing well, feeding with food soaked with gc, focus, touch of garlic

thanks!
