Hey Alex Pueblan's are awesome snakes!!!
30 gallon long should be fine for an aldult.
My Pueblan milks are kinda flighty and nervous Other than that I would call them tame.
Temps...approx 75 cool side to 85 on the hot end.
$$ depends on colour phase, size, etc.
If you pay around $100.00 for healthy happy C.B. hatchling. I believe that would be an OK $ . Hope this helps
This is a pic from last year. That my good buddy Joe took!!
