You shouldn't be housing them together or breeding them for a number of reasons, a lot of which saphhire stated. And while I am glad you are so exited about having another snake for a while, you should be prepared to house them seperately. If I were you I would seperate them right away. It doesn't cost that much at all to modify a rubbermaid to be a good enclosure for the snake. (If they can be kept in rubbermaids, I'm not sure.) But please seperate them soon, and moniter them to make sure no one is sick!
I would give more advice, but I really need to sleep.. I can barely understand what i'm typing.
Anyways, get them seperated, and make sure they're healthy. Good luck.
