This subject has been touched on a lot, if you want to read through pages of responses just search the question. I believe majority of the members on here would say no.
Short and sweet...bps are solitary animals and do not need or want "friends". Having multiple snakes in the same tank can stress them out and stress causing them not too eat. If you want to do it to save money, bps aren't for you, if you want to do it to save space, switch to tubs.
Oh, and my other thought on the matter. Just like the debate over tanks or tubs, breeders use tubs because they work for bps, typically much better than tanks. If bps didn't thrive in tubs, breeders wouldn't use them. If breeders could house multiple snakes in the same tub wouldn't they do so? It would save a tremendous amount of space if they could be housed together, but breeders keep one snake per tub...
