Don't stress out over it. I moved 26 tanks just 3 years ago when I moved to my house. The advice I'm about to give you will give others a heartattack. The day of the move, I woke up early and put all the fish in bags just like I was shipping them. I boxed them up, then drained the tanks. I left the gravel in them, with just a little water. If the tanks were too heavy, I took everything out. When I moved, I set up all the tanks and started filling them as fast as possible. A garden hose worked well. Fill buckets with hot water and dump in the tanks to get the temp adjusted as fast as possible. Float the bags for 30 minutes, then add to the tanks. Load those suckers up with chemicals and you'll be fine. Don't worry about beneficial bacteria or all that other "mumbo jumbo". Its an easy process, don't let it give you a head ache. All fish are a lot more durable than you think. If people can ship them in boxes for days at a time, moving them 1 day won't kill them. I never lost a fish doing what I did...I did 15 discus, 2 flowerhorns, 30 rams, MANY tetras, africans, SA cichlids, CA cichlids, and a whole bunch more. Good luck with your move!
