OP, I had my large male in a 61qt tub that measured 39"L X 17"W X 6"T. Almost the same floor space as a 40 gal breeder.
It was easier to maintain temps and humidity, plus the small vertical space may feel more burrough like. The biggest thing I noticed when I moved mine into tubs was that their feeding response went from "indifferent" to "highly enthusiastic"...
