I got a regal tang with a slight case of ich yesterday. I got it at no charge and wanted to see if I could cure it. In my QT, I treated it with melafix and pimafix. It looked okay when I got home this evening but I continued the treatment. The course is 5-7 days I believe. 2 hours after the second treatment, it's laying on it's side and barely breathing. I took it out of the treated Qt and placed it in another QT. Why would this have happened? Could I have overdosed it? I'm using professional strength meds and I'm treating in a 5 gal QT. Is there anything I can do at this point?
