I guess it all depends upon where you're moving. I tore down a tank I really like before moving from Texas to California. It's not at all easy to move tanks, even tiny ones, very far. Now if you're moving down the street, you might be able to do it with much effort and some damage/loss of life. I waited until I was in a stable living situation here in the bay to start working on my new setup, and I am glad I did cause moving a half mile from Berkeley to Oakland was hard enough without having to worry about killing all my pets.
