First off when people say thats "way too big" they're just saying what works for them its not a rule or something you HAVE to abide by or else your snake will die... To them its "way too big" but to me it can work just fine... I started my first BP off in a 40gal and never had any problems... Its really not [I]that[I] big once you add in two hides a decent sized water bowl and something to climb on(if you wish to provide your snake with that)... The hardest part with a 40gal is the glass and keeping humidity/heat inside... It can be done its just a pain in the arse especially if you live in the north where humidity is crap during the winter... If your getting a baby I say save yourself the 100$ your gonna spend on a 40 gal and just get a 66qt plastic tub... youll never have to worry about not enough humidity and the heat situation can always be tweaked to get where you need to be.
