I've had a new pair of blue throat triggers in my QT for little over a week and this am I saw them both with Ich spots. I dosed Cupramine. Do I gain anything by taking the fish out of the QT, cleaning out the QT tank completely and then refilling it with water from my main display system (water that would normally be thrown out during a water change)? Will that help the chances of survival or should I wait until I see if they survive the cupramine dose?
