Sorry, I'm just waiting for the arguments to start. To be helpful (I'm sorry for my first post not being helpful in the least) I can give you my personal opinion.

Snakes do not need friends. If you are planning on housing them together, you're going to have a lot of people on here arguing about what a terrible idea that is. Personally, again, I have been keeping snakes for...almost 4 years now? I would never house them together. The cons outweigh the pros and I don't consider myself nearly experience enough, nor have the unlimited time to make it work. Being a new snake owner, I would not advise getting your snake any friends.

However, the good news is, you can get another snake! I would get a separate enclosure for it. Can it be done? Yes, but it'll take you more than 4 months to figure out how to do so safely.
