Green Tree Pythons fit the bill as an arboreal reptile with a dedicated community that surrounds it. This is important to us because they have studied there reptile as deeply as we have studied ours and we can both benefit from each other's efforts. And, if there is one snake that would be a natural transition for us, Green Tree Pythons (or their boa counterpart, the Emerald Tree) would be top of the list for many of us.
