I don't know.. This is how I see it, pretty simple.
Ball pythons are not social animals. Therefore, do not force them to live with another snake. The only reasons I've ever heard to house snakes together is pure selfishness from the owner, since they just want things to be "easier."
They don't like it. So why would you do it? Yeah, animals can live and be "fine" in a situation they are not meant for, but why would you want to do that to them?
