What size tubs for racks?

I want to go to a rack setup and want to know what size tubs are normally used for the following.....

Adult females = how many qt tub?

Juvy = ?

I have no problem building/purchasing a rack setup but dont want the adults to bee to confined or the babies to have a tub too large.

Any links or comments on how your full rack setups are would be greatly appreciated.

Adult females are generally kept in 41 qt tubs although mine seems content in her 32 qt.

Juvies around 16 qt.

I currently have 6 qt, 15 qt, and 32 qt tubs. I expect as some of my females get bigger than their "just barely adult" size, I will want to move them up to 41 qt. I know some people never go larger than 32 qt, but to me it seems like it would be kinda cramped for a really big female and a male put together during breeding season.

I use Animal Plastic racks. I like the 32 qt rack for juvies/subadults. Each shelf holds 2 15qt tubs or 1 32 qt. So mine hole 7 sub adults or 14 juvies depending on how I set em up. I will be ordering a 41qt AP rack for my adults soon

Awsome just what I needed. Perciate it guys!
