You would be heart broken if you took this snake, and put them together without quarantine - and then something happened to your first one.
Can they be housed together? Yes - if you're experienced enough to read the subtle signs of stress. Ball pythons don't cuddle - they compete for the perceived best spot in the tank - when "cuddled", one is being dominant, and one is being stressed by being dominated. Even when given huge enclosures - when they're "cuddling", they're competing - kinda like two kids playing - one kid doesn't even realize he wants to play with a particular toy, until the other kid decides to play with it - then suddenly - it's the best toy in the room.
Do we recommend that someone new (and just a year is new) to ball pythons do it? No - not really.
Think about it - wouldn't breeders save space if they could house multiple ball pythons in one enclosure? Do breeders do it? Nope. We prefer to keep them one to an enclosure, except when pairing for breeding. And then, it's only for a few days at a time.
