If this worked, this is a couple of my breeding racks. I usually keep 2 females per tub, and cycle a male through all the tubs. Bottles can be used instead of the auto watering system, but I like low maintenance, and this setup can go 2 weeks with no maintenance if needed. I have to find a picture of the totes still.

Edit: Best I could do was a link, I can never get pics to load right for some reason.
