i just moved 2 weeks ago and i have a few tanks too. I left everything in there in my 29 gal except the filter and air things. i have 7 fish in there and they all survived . they were the last things i took and the first things i set up. I got all the advice from the nice peeps here and it was all good. I also drove embarassingly slow too but you have to so they dont get swached around in there , but i kept my decor and fish in the tank.
