I've had a new Foxface Rabbitfish in my 20g QT for 2 weeks. I treated him with prazi and maracyn for a week, did a water change yesterday, and did a half treatment of copper, as part of quarantine. When I got home today, I see him lying down on his side. He's camo, is breathing extremely rapidly, and is flapping his wings still a little.
He looks like he's dying. What do you think?
