humidity is super important, if it drops too much you'll have problems. If that happens you may get RI type symptoms that go away with corrected humidity. They should be kept cooler than bp's, I have my rainbow basking spots at 85, and the boas and balls at 92, but you need to read up on their care before you do anything. They're usually considered intermediate snakes because they give some keepers a lot of difficulty. Corallus.com has a caresheet, as does NERD, and there are several other good ones around. Great snakes, I have one that's a real sweetheart. But then again the meanest snake I've ever owned was a BRB, 6 feet of pure fury, but unfortunately I lost him to a stupid cooling accident when a roommate turned off the heat, I felt terribly bad about that.
