Well got a reply back this morning....
"He’s full grown, about ten years old.
We don’t generally weight adult snakes unless they look emaciated. No known issues.
He’s easy to handle."
Not a lot of help there.....
So full grown is ???? 6 feet? 8 feet? Longer???
If it's (no clue on sex) 10 years old it another 5 to 10 years in it's life span, maybe more?
It would need a standard terrestrial enclosure or an arboreal enclosure with lots of climbing?
