I don't think a 41-qt tub will work for a large adult, but a juvenile will be fine in it for quite a few years. My adult male and female are both just over 6'. She gave me 25 babies earlier this year. I'm designing a rack for them and my holdbacks based on the Sterilite 74-qt under-bed tubs. Some people also use the IRIS VE-175 Christmas Tree tubs for their adults since they do like to climb a bit and will make use of the vertical space.
Temps from the mid-70's low to mid-80's high. They need high humidity so I use cypress mulch for them with a UTH on a t-stat, no lights, RHP, or CHE.
