Thanks everyone. They are in a hospital tank but apparently what i am doing is not working as they keep dying anyways. I have thrown the u.v on the main display to try and help kill any that are in there. And the fish we'll i guess all i can do is sit and watch them dye. I have put the copper in but it doesn't appear to be helping. I checked the copper levels and they are sitting at optimum treatment levels so it should be working. I wonder if they are all just to far gone???
The regal is the only one that looks okay. I may move her back into the main display and hope that she makes it. Maybe the hiding spots will be less sressful for her and maybe she will fight it.
I don't know
I am at a loss.
