Puffed up lips, can't close mouth...

I have an older Osellaris clownfish female, she's probably about 4 years old, but thats a guess by size. She's currently got very puffed up lips, can't close her mouth, and is breathing heavier than normal, not eating and lethargy. This cropped up over the last three days. This fish has been in great health prior and was fully QT'd prior to going into my tank. There are no signs of Ich, flukes, velvet, brooknella, etc, etc. I'm thinking this is some sort of bacterial infection, and should treat as such.



I was thinking I should treat with Nitrofuracin Green and see if that works...

Can I treat her in the DT? I ask because the QT is full with a fresh round of Cupramine started on a couple fish, and then this popped up. It will literally be about 3 weeks before the QT is clear, but this clownfish will be dead by then I fear.
