I have 4 different juvenile tangs. They all have ich after introducing 2 new ones. I’m about to move next week. How do I go about QT them, treating them properly for the several months, also how do I treat the DT (I have a reef and anemones), and lastly should I still save my water as planned and put it back in the tank when I move to the new place which is literally a few doors down and one floor away from my current place.
