I have all my snakes in tanks at the moment. but it went from 2 to 7 snakes in 2 months... So next month Im welding a snake rack and putting them all in tubs...because I have alot of humidity issues in my house and Im running out of room for tanks. I kindof prefer tubs. It saves space, the ambient air temp stays up, humidity stays up and I think it may make them feel a little more secure IMO
