Extra slot in my cb70

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.

I think it might be cool to branch out into a bunch of less common species of snakes. I know jjspirko has done this. Maybe he has some input?

Anybody? Anything? Sorry about being impatient.

Dumeril Boa, Blood Python, Taiwanese Beauty Snakes or a Carpet Python.

Carpet pythons are deff cool,
im in love with the Jungle i got.

not to mention the color of them is incredible..

bloods are also really pretty... but dang i saw a pic of a full grown one being held by some one... dang. lol

Macklotts:gj: Out of 27 snakes with 25 of them being BPs, she is still my favorite. Uncommon enough to be something different and they have fabulous personalities.
Dumerils or Carpets would be next on my list after that.
