if the tree boa is not a huge one, a 20 inch cage would work. most of the time he's going to be wrapped up on something any way. the 24 inch wide one would give a little more thermal gradient from side to side. i use ceramic heat emitters on arboreals, they work great. you can arrange the perches/branches to give him different spots to bask. the barrs you can get with 2 perches that allows them to choose where they want. always use a thermomstat, they really work!
