Someone Please Help Me Choose a Tub Size for my Rack

I'm ordering my first rack this week. Think I'm gonna go with Animal Plastics as its more cost efficient for me at the time. I have a male pushing 600 g, a female pushing 600 g, and another female pushing 200 g. I want to get a rack that will fit them all full grown. From what I've noticed, most people get CB70 but I've been talking to someone lately who thinks I should get 32 qt and then put a divider in those for my 200 g female. She seems to think 32 qt will be enough for them even full grown and for breeding. Does this seem right or should I got for the CB70?

***Mind you, I will not just be throwing my 200 g in a CB70, I was thinking about keeping her in a smaller rubbermaid for the time being or possibly fashioning some sort of a divider in it, as well as for my other two snakes. Also, I do not want to build my own rack, I want to buy one.

Thanks in advance!

Get the 32qt animal plastics rack and buy the dividers as well for your smaller one.

I'd buy the CB-70, because eventually you'll have females that could use that space. If you want, you can easily make dividers in the CB-70's as well using wood or plexi glass cut to fit. :)

Or, you can buy the 32 quart and pre-made dividers now, and later down the road invest in the CB-70 for the big girls.
