question about multiple BP's

[xFenrir]

It's not a good idea, and it's very stressful for the snakes. Ball pythons should always be housed alone (for their permanent homes).

I'm assuming you didn't quarantine the new ones either.

Maybe you should think about a small snake rack, with tubs instead of tanks for your snakes.

Especially the quarantine part. Even if a new snake SEEMS healthy, it doesn't mean they are.
