We have BRBs here and have had CRBs in the past. I personally don't keep them very differently. For both species i've found misting twice a day, a large waterbowl, over head heat rather than under belly and a good moisture retaining substrate like orchid bark (or whatever it's called over there) does the trick with CRBs and BRBs. hot spot is maintained around 88-90 with the cold end not being allowed to drop below 75 in a 4ft viv.
