Well -- I am bit stressed because I really blew it in my QT -- I treated with prozipro following the instructions and it killed them all. And I had a cockatiel die just a few weeks ago from something piercing her gut, I have lost a mandarin, 2 tangs, an angel fish and perhaps the neon gobies in QT, and I have a friend who has an aggressive cancer that just showed up suddenly all over her body. I think I am getting paranoid... justifiably. Sorry .. I guess I am saying too much just because a fish would not eat another fish....
