I have only one BP and she lives in a tank. As I posted in a previous thread, I've not had any temp or humidity issues for a variety of reasons.

However, I'm one of those people who loves to build things, and I do see myself getting 1-2 more snakes in the future. So I plan on building a wooden frame that will house 3-4 40 gal tanks in a stack. I have already started working on plans for this, even though I currently live in an ity-bitty apartment and will not have the space for such a project for a long time. I feel that this will be the convenience of a rack system combined with the beauty of a tank, all the while providing security and happiness for the ones that really matter - the animals.

Honestly, I think that as long as the snake is happy and comfortable, the tank/tub issue is a personal one. If you've got bunches of snakes, tubs are easily the winner but if you've just got the one, then I can't really see the "added effort" of a tank being all that big of a deal. Just my two cents!
