Keep them seperated for at least 3 months.. I hope the MOD that has the pic will see this and post the pic of a BP that ate another BP in its enclosure and the end result was they both died.

Males will fight. Even a female which has never seen another snake in her life may bite the newcomer. My female bit her first boyfriend when introduced during breeding season. I kept seeing these little bite marks on him. She did it quite a few times before they locked up and she figured out what his purpose was.

Also keep them apart for health reasons. What if one gets an RI? The other will mopst like get one too if housed together and drinking from the same bowl ETC..

What if the new one has IBD? Not as common but a reality none the less.

It really is best to keep them apart. In the wild they are solitary animals. They get no "enjoyment" out of having another animal in their den with them. It is not better for them. On the contrary.
