I HIGHLY recommand to not do it. I said that from my own experience.

10+ years ago, I bought a pair of ball python. I was housing them together, but feeding them out of the bin at that time. Well, I lost the female. I think she also had parasite of some sort, but the male was attacking her and she was highly stressed.

Also, if you are getting a new animal, you should put them in different room if possible. Quarantine should be. (In case one of them have parasite or anything that could infect and risk health to the other).

You can use a rubbermaid tub while in quarantine if you want. And when done, you can move to a tank if you prefer the look of a nice enclosure.

good luck !
