Hi! I have one enclosure with 1 ball python, he (or she, we haven't taken him to the vet yet since it's very cold outside and I didn't want to risk anything in transportation). He's about 6 months old, I've had him since about a week after hatching. I was wondering how safe would it be to introduce another ball into the enclosure? How old would it have to be? a hatchling or find one about the same size? could it be a morph, or wildtype (like mine), I've never seen morphs mixed in a pet store, but I don't know if there's a reason.

Anyways, thanks for all your help!
