Tub with a rtb?

I am looking to get a RTB at the Hamburg show and have a tub ? for a baby, can he be housed in a 41qt tub for a time till i build a new enclosure with a rhp. till how big can he be housed in a 41qt tub?

A baby would be fine in a 41q. Our boas are about 9 months old and currently in 15qt's. I will probably be bumping them up to a bigger size, probably 40ish qt, before the summer comes. In general, they are the opposite of bp's though. If they can be comfortable in a 15-70qt range, if you can , go for the bigger end of the spectrum.
