I've decided to follow your lead and build my own rack. Based on what I have available locally, I've decided to go with Vision mouse tubs. I'd like to go with 10 or 12 tubs (2 tubs wide and 5 or 6 tubs tall). I'd like to keep 3 or 4 females and one male per tub. Assuming 5 mice per tub, should I go with the small Vision tub (12" x 7.5" x 4" or the regular Vision tub (19" x10" x 6"? The larger size seems like it might be better, but I'm concerned about the mice needing to reach up about 6 inches to get food and water. Is that a problem? Any thoughts would be greatly appreciated.
