These guys dont get much fatter than a broom handle * a little, but not really* My BIG girl is about 4 years old and is at about 45 inches. ( a little under 4 feet) Alot smaller than a ball python, for sure.

I have three of these guys and save for the Neonate Girly they are ANGELS. As with all snakes, each one can be different, but really once i have the little girl out, shes fine. not too much fuss, and mostly shes all bluff. I see it as shes much much much smaller than me, and Im a huge big tree with grasping fingers, of course shes going to hiss and try to look bigger!

Enclosure stuff:
Temps. Keep them just like Bps and most other snakes. 85-88 hot side, and 75-78 cool side.

Include hides, they will use both.

These guys prefer to climb, if you let them. But do fine in a rack system as well. They absolutely will utilize any branches provided though if you decide to give them a more airy enclosure. * just be sure to provide plenty of floor room too*

Feeding:
Great feeders, all three of mine eat for me every time i offer food. Without hesitation, and actually have a pretty strong feeding response as well, so watch those fingers

I do not think there are any downs to keeping these guys, Just feed them LESS. They do not really do well on a weekly feeding schedule ( for adults at least) I feed every other week, sometimes longer. Boas do much better on a more reserved feeding regimen.

( I recommend Buying directly from Gus. Gus got all three original animals when they were first imported * no others were*, and if i recommend anyone, it will be him. )
