i checked out reptiletubs.com and they had the ve series which is huge, but i was just wondering if sterilite, or rubbermaid had any large tubs. i picked up a 90 qt sterilite from walmart, at it's pretty much the same size as a 20 gal tank (12x30x12). i was just wondering what some of you guys use for your boas. my guy is about 3.5-4" right now. i plan on getting a RBI 4x2 cage, but at the moment i just need a tub for him. thanks for the help.
