I have a 75 gallon fowlr tank, and need some help. My tank that just started leaking at one of the seams, I know how to fix this but I would need to take most of the water out. I had had just finished cycling a few days ago. I only have one fish in there at the time and that is a less than 1" yellow tang. I was wondering if I could keep him in a 5 gallon bucket for 3-4 days. I would just take some water out of my current tank and add a filter, heater, and powerhead. Would that be OK?
