Well I've got 36 of them in tubs from babies hatched last season to very big adult females. If tubs weren't okay for them then I'm just not sure why my biggest female whose over 5 feet long and over 3,000 grams in weight would be as big and healthy as she is.

It's good to listen to advice but it's always better to take that information, look around, do your research and then decide if the advice is really valid or not.
