While I generally don't believe ball pythons should be housed together, insulting the OP is not going to make them see your point of view.
If both animals are eating and overall healthy it won't kill them to be housed together. Keeping two animals together is more difficult and opens an array of potential problems. If these animals were truly extremely stressed from living together that stress would cause them to either stop eating and/or possibly develop health issues. That doesn't appear to be the case here. These animals don't live completely solitary lives and probably do bump into each in the wild outside of breeding season. Unless you are going to tell me you are a parseltongue and have personally spoken to these snakes I don't think you should insult the OP. If you truly believe these animals should not be housed together why don't you put together a logical argument as to why the OP should separate them.
