As long as you give them alot of egg crates and paper towel rolls to hide in. My enclosures are 30gal tall tanks and I have well over that in them, but you need to make sure your male population doesn't get out of control.
Cool if you use the rubbermaid tub make sure that it is clean and free of any type of residue and that it is not scratched up inside. And just cut out a small portion of the lid and secure some screen over the hole.
But I still suggest glass it just seems safer to me. :wink: See when I started mine I was very worried just like you about escapees taking over my house.
