Rat tub size...

Are the 32 qt iris tubs too small to use in a rat rack?

I'm building a new snake rack and have leftover tubs from my old snake rack i want to use, I'm just not sure if they're big enough.

They would be okay to use as a maternity rack, but keeping breeding pairs or trios in them really wouldn't work. Rats are animals that need a ton of space, and the cramped size of the 32 quart would cause fighting and possibly health issues.
