oh no... the medication caused the death of all your fish or the disease did?
A couple weeks ago, I saw a few salt-like crystals on my puffer and he was exhibiting erratic scratching and darting behavior... Since my QT is currently occupied I used kick-ich in my FOWLR tank. I have kept up the treatments religiously and have only two more left before it's completed. I haven't really noticed a difference in the puffer's scratching behavior but I can't see the salt-like spots anymore ... what worries me is that I may have been imagining the spots all along, since they were only in a few places. Am I endangering this fish by adding the kick-ich? Or is the concern just that I am not effectively treating what he's had.
Also, the fish has never shown ANY sign of loss of appetite or heavy breathing. He looks entirely healthy except for occasional scratching.
