That's the hard part I cannot move the two big tanks out of the room. That much is certain. I could put Gnag in the Critter Keeper and Bumpy in the 5 gallon, but that would mean I'd not be able to feed the two of them for that period of time and they'd both be cramped in a very small space . How long do you think it would be for it to be safe for me to put them back in their tanks once we'd finished painting? And would I have to completely disassemble the tanks after because of the fumes?
