Rubbermaid tub sizes

I'm about to build a rack and wanted to ask a question before I spent 40-80$ on tubs. Is a 31qt shallow tub good enough for an adult ball, and it a 16qt shallow good enough for a hatching- around two year old ball? These are the 6.9" tall rubbermaid tubs, and I'm using them because to me they look to be built better than most I've seen.

Those will work just fine. A really huge adult female may want something slightly bigger than 31 qt, but I know a lot of people get away with putting them in 31 qts their whole lives.

Alright thanks! I've got one that a sterlite and is about 15" longer I was going to keep for a large female.

Good question, I've been trying to decide what size rack to buy next. :D
