I don't know about the stress par tor the perfect husbandry thing, but we've had ours for 6+ months now, and he's a fairly easy going guy.
ambient temps of my critter room, UVB, and daily spraying for humidity. A bowl with the bug of the day ( which he never finishes). Not much more difficult than some of our other critters.
Ours is currently around 8" and getting thick in a 30g vert conversion partially planted tank (they can destroy most plants) with a full screen door.
I only have the one picture, because he's not the easiest for pics. http://ball-pythons.net/forums/showt...the-collection
As long as you can get a healthy specimin, these guys can be a good display, but for the most part don't enjoy the handling.
