I've also wondered about this. When people post pictures of their setup in a glass tank, occasionally you'll see the comment "That tank is too small for your adult." But, I've seen more pictures of racks/tubs that are, imo, small, for adults. Alot of people have said they just use 41qt tubs for their adults I think? Those seem too small, to me anyway. They seem perfect for my juvies, but for adults... Is there a reason for this?
I'm just trying to figure out the right size tubs to get for my rack..
A 41 qt will comfortably house your largest ball python. I house all of my adults in approximately 41 qt tubs, sub-adults in 32 qt tubs, and hatchlings in 6qt tubs.
