Yes a tub is much much easier to get things down... I like you started off with glass only to spend countless hours messing with different stuff to get temps/humidity up... I got them right (still use a 40gal for my RTB) but spent extra cash and wasted time trying to do so... I'm much much different than your average BP owner and believe the more space the better... I started my first baby ball off in a 40 gal and never had any problems with feeding stress or anything... It really all depends on your ball... For beginner I would reccommend starting with something smaller just to prevent any possible problems... some people start off with 12qt tubs and others like me like bigger tubs and mine are in 66qt... Its really up to what you would like your snakes to have as long as you know there are potential problems(not eating, stress) with a larger tank. Nothing saying this will def. happen as I have never had this problem but it can be an issue... Youd set a tub up just like a tank... heat pad on one side hooked to a thermostat, 2 identicle hides(zilla makes black plastic ones... I use the smallest for my babies), a water dish, and something to climb on if you would like... Id try to get the snap top tubs just bc they lock somewhat to prevent the lil guy from escaping... I put a small brick on mine to prevent anything like that... I can go into more detail if you need but thats pretty much it...
