What should i do....

You can also consider buying an inexpensive rubbermaid or sterilite plastic tub as an enclosure. They actually hold heat and humidity much better than a glass tank does anyway.. and only cost a few dollars.

I house two of my bps together and so far I have had no problems. They both eat every week. The both shed normaly. They are not agressive and they do not seemed stressed in any way shape or form. If I start to see signs of stress I'll separate them, but so far all is perfect.

It seems like somehow housing snakes together ultimately becomes the theme of every thread. I'm amazed that people don't do research before buying a living animal. Their captive habitat should match closely to their natural habitat. If they thrive in packs in the wild then by all means house them together because they are social animals. However, snakes are not like that. In the wild they are solitary animaly, so why in the world would anybody think that it is a good idea to house them together in captivity? As far as 'obvious signs of stress', they can't talk. They can't tell you that they want to be alone. Just because they eat and shed regularly doesn't mean that they aren't stressed. I'm sorry, but it you aren't going to properly care for an animal then you shouldn't have one.
