Thank God they are in my QT tank right now. I have 4 tiny fish in my QT, they are all small. Firefish, R. Gramma, Tailspot Blenny, Randalls Goby. All are still eating pretty well. I'm going to use a cupramine base treatment instead of hypo. I'm likely going to do a FW dip before they get introduced to my DT after treatment. Do any of these fish not really react well to Copper? Bottle says 2 week treatment, then I add another 2 to view and make sure it isn't present? Wish me luck.
