OK so in two years with no issues will you allow me to say that they can be kept in larger enclosures?> So in your long history of keeping BPs how many times did you set up a 66qt tub for a baby and test it out? How many times did you stray from the norm of a 12qt tub and try something new? Im going to guess prolly very few times if ever... set up a 66qt for your next baby... try it out... then come back to me... Ill bet you all 11 of my snakes you dont have a problem as long as proper heat/humidity is met... To say a 66qt tub is too big is rediculous.
