Yes a 41-quart tub will be way too big BUT if you clutter it up with fake vines and hides you can make it work. Boas seem to adapt better to oversized enclosures than ball pythons do.
Agreed. ..I have a 8 month old in a 41q and she has no problem. .she could definitely go into a 28 qt but I have an open 41 so why not .
