Just getting into corns - have a question

What is the smallest corn (in length/inches) that I would be able to get considering the smallest tub set up I have is in a RBI Sweater Box rack.

I am in the process of getting my first corn and would prefer to get it as young as possible so I can raise it up but I understand that I have to consider the tub size.

Any helpful suggestions on this topic.

Thanks.

If it is a 32 qt tub, then you can house a full grown corn snake in there. But I do notice my corns like to cruise around a bit more so I give them a bigger tub. I house my full grown adults in 41qts.

I keep hatchlings in shoebox size tubs and they do well for up to a year depending on growth rate. I then move up to a medium tub size between the sweaterbox and shoebox size then finally the sweaterbox (32qt) my adults are compfy in these and do very well.

Ok, that info helps. I can certainly rule out getting a baby. I have an opportunity to get an 8 month old that is 2 ft long - that may work with my tubs.
