Here's my thoughts on this matter...

You wonder if it's OK to keep two ball pythons together. (Supposedly both of them male...hopefully they've been sexed correctly!) And yet...with all the good advice given about why it's a bad idea you persist in insisting that it's "fine" and you're going to do it anyway. Which leads me to believe that you didn't really wonder if it was ok or not...you just wanted to get a rise out of people.

That being said...I believe there are a LOT of good reasons for keeping them separate. And I've yet to hear a single good reason for why they should be kept together. But it's up to each individual to sift through all the responses and decide what they believe is fact and what they believe is nonsense. It's up to each individual to decide who is worth listening to and who is speaking out of ignorance. None of us can make those determinations for you. All we can do is present the facts as we understand them, and offer our opinion on those facts. What you choose to do with them is up to you.
