Hm... I suppose you can fit smaller species in there like sand boas, rosey boas, rubber boas, angolan pythons, spotted pythons, and children's pythons.
Most other adult boa/pythons need more space than a 41 qt tub. You can fit babies and juvies of the larger species in them fine though.
Btw, not everyone reads all the threads. They could have missed the post. Chill......
