I am thinking about switching to tubs but i want a set up for two tubs on on top of the other in a rack made for two. Whats better for the tubs the belly heat or the back heat? And what should I lay down in the tubs? Newspaper? etc.

Yea I hate those bulbs in my tank too but he seems to be smart around them yesterday I got freaked out when I saw him go near it and I watched him he bumped his head into it lol and took of hell of quick. So I think he is somewhat smart but I still want to get rid of that tank and get me the two tubs so that when I get my girl or my new male which are going to be about 2 feet in lenght or more. What size tub would I be looking at that will last me forever and I dont need to keep on upgrading tubs?
