I have my BCI and BCO in tubs right now. They're only in the 150-200 gram range though so they are small now, but i will be putting them in 4x2's soon. I keep all my herps in the same room. My ball python, my jcp, and the boas. Humidity is about the same range as bp's, just a little higher. My other advice would be, get a RTB. They are awsome. Dont get too large and have great temperments. And they are beautiful.
