This is our newest, just brought him home. We adopted him, I think he's about 2.5 years old and about 40 inches. Thus far he's been real active, I rearanged his enclosure and he's been exploring it since. Tomorrow we'll change the bedding and give him another heat source. I've temporarly put one of my thermooters in there, just to see how the temp is and what the humidity stays around. Right now he's got a solid screen top, I've not had much luck keeping the humity high enough, so we'll have to see. More pictures to come as soon as we get his enclosure put together. Maybe tomorrow he can come out and enjoy our 'snake tree'...
