My perculas have some parasite?

We have two true perculas and have had them for about a month. They were tank raised and have been in perfect condition until about a week ago.
The female, has some sort of white thing inside of her mouth, and she is unable to close it. we treated it with methenal blue and it got the thing to shrink, but its still there.
now, her and the male are both showing signs of white spotted things growing on them, which arent being effected by the methenal.
Ive come close to ruling out Ich.
I can't find what these external things are, and our perkies are dying.
Weve been doing a copper treatment in the quarentine tank with the perculas.
help!

 

Welcome to 3Reef!!!

I wish it was under better circumstances.

Look up Clownfish disease (Brooklynella)
Also, Marine Velvet (Oodinium)

 

Hopefully it will subside quickly and isn't ich!
