I got a new tank at Petsmart yesterday because it was on sale. It's a 40gal Kritter Keeper with the sliding lid. It's 36" x 18" x 16". Basically what I'm wondering is when I should try to switch my ball python into the bigger tank. The one I have now is a 20g tall. This new tank sames a lot bigger and I don't want to stress my snake out to much by making the switch. The snake is about two feet long now.
