Tubs:
Hatchling - Shoebox
Yearling - 15 to 28qt depending on growth rate
Adults - 41qt

Feeders:
Forget mice, they are a waste of time and money. Get your balls started on rats. Much better for them. Even the smallest hatchlings can take appropriately sized rats. Rule of thumb is as big around as the fattest part of thier bodies or 10-15% of thier body weight every 7 days.
