I live 2 years without a table to eat at because of the number of tanks in my apartment. We moved so we would have more room.
Now, we have an entire side of the garage dedicated to a R/O water tower, two tanks in the garage (a 100 and 180), I have 3 tanks in the living room so that half of it is designated to just fish, and we are looking at a 600 gallon build very soon here.
For the move, we had to get everyone over in one weekend which meant moving about 3,000 lbs in a matter of 1.5 days down from the third floor and moved to a new home. I dont remember sleeping much that weekend. Also, because of the amount of effort we were putting into getting all the fish settled at this place, we literally sent the first two weeks here sleeping on a blow up bed. I didn't loose one fish of the probably 150 or so, which included everything from 25+ discus, to 15" TSN's and hybrids, to more random guys than I could hope to count.
I never want to move fish again, but it inevitable. But now we are prepared, and we don't live on the third floor.
