Moving fish back to DT after copper treatment in hospital tank???

[Aquattro]

For one, the ich is still in the tank, so they may get reinfected. Or not. When I move my fish back, I'll do a larger water change on the treatment tank using tank water. That will acclimate them. I'll then scoop them out of the tank with a container, walk them over to the display, pick them up with my hand and drop them in the display tank. Easy peasy
