I have an AP cb70 rack with three slots. I have my boa in on and my BP in another. The boa seems like it will be fine in there for a little while and then I will be getting her a 4 x 2 enclosure probably also from animal plastics. If I were to be getting another reptile what would all of you recommend? I am open to snakes that will eventually outgrow the tub as well as herps other than snakes and I have no immediate plans to breed the ones I already have.
