Well when I rescape I turn off filters and heater(s) just in case the water level gets too low then it dont affect them so much. Recently I did a serious deep clean/rescape. I drained half the tank and put the fish in a bucket of tank water with the heater and the filter to keep the bacteria alive. Then I drained the rest of the tank and cleaned the sides. Rescaped and everything else. Filled the tank up. Hooked the equipment. Acclimated fish.
A small rescape should just be on a water change day and then just move things around. This is easier in a non shrimp tank as they tend to get stuck in places and you may not see them again. But if its like just pruning and replanting then you should be fine. No moving fish or anything just prune, replant, and rescape.
