Looks like I may be acquiring a pair of BRBs...so, I'm attempting to learn as much as possible in a pretty short time frame. I'm struggling to find a good tub size to use for an enclosure. The current owners use a glass aquarium...but I don't like using those due to the humidity nightmare (and the fact they suck up space)...so these are adults. What size tub would you use? I swear I saw sweaterbox somewhere? But I saw someone else post pics of a regular Sterilite 66 Qt (although that doesn't give 4-6ft of floor space). I think they are in a 30 gallon glass tank now (I have no clue if they are separate or housed together).

Any help is appreciated!
