The emerald tree boa is aboreal, meaning he lives in trees. You'll want to buy/build a tall enclosure with a lot of sticks for climbing and resting on. They also appreciate a humid environment, as they are from very tropical rainforests. Be careful when handling the snakes, emeralds have a reputation for being pretty nasty biters.
I'd imagine the tree boa has the exact same requirments.
