Tank is 110g and has been up and running for 10 months with no probs. I didnt know you were not supposed to medicate fish, the fish lady told me to go ahead, ****.

What should I do now if I want to continue the tank?
Not saying don't medicate fish, saying don't medicate Lion Fish. there are certain fish that can and can not handle certain types of medications. Like you eel for instance, will not make it if you use cooper or even if there is cooper residue in the tank at very low levels. A lot of fish can not handle cooper; but you need to research and check before medicating and trusting your LFS and compare it to what you have in the tank.

QT, QT, QT all new fish and protect your display....dang now i sould like Wet Web Media! LOL

Hate to hear about your looses, but don't give up. Every failure teaches you something!
