OK I'm officially addicted to Ball Pythons. I have 3(2 in terrariums/1 in a tub) and I'm commissioning my father to build me my first rack system. All of my snakes are still very young at 6-12 weeks. I plan on acquiring more young ones on up to yearlings, and need to know what size of tubs is advised for I guess what would be the first half of their growing period. Up to 3 feet maybe. The adult size 41-45 quart rack will come in the future. Size suggestions?
