If you go to the ASF forum and look at the tub design, you'll see a real nice setup for mice/asfs. I use the same 50 or 55 qt tub. Mount a water bottle on the OUTSIDE of the tub. And if you're handy, buy some 1/4" screen and try to make a food hopper and mount that to the inside of the tub. The ASF forum really shows a nice tub setup like I said earlier...
