Welcome to the site. I think you will find tons of useful info here
As for what you can house with a bp....I would say nothing. Snakes really should be housed alone with the exception of breeding. Do a search and you will see why. Some of the issues include: if one gets sick, the other will likely get sick, if you have a regurge you can't tell which one, and cannibilism.
I hope you enjoy our little community, as there are many many experienced keepers and breeders here.
