I keep my brazilian on sphagnum moss in a melamine cage that holds heat and humidity well. I keep him at around 82 degrees like my arboreals and the humidity around 90% at night after I spray and then the cage is allowed to dry out to around 65% until I spray again. I haven't found them to be more difficult to keep than my amazons or chondros and my rainbow is really mellow. Even as a youngster he was calm. When I first got him from my friend who bred him I kept him in a regular glass terrarium type cage for quarantine. I had to cover the top with plastic to keep the humidity high enough and the temps were more difficult to maintain. I now have him in my snake room in the custom cages my corns also live in and he does great in there.
