Recommend me a tub size for leos

I am looking into putting together a small rack and am wondering which size tub you would recommend that could provide a good size home for a leo through all it's life phases? ( hatchling, juvi & adult )

Thanks in advance guys

I would put a pair or trio into a 32 quart tub. A 16 quart is acceptable for a single leo, but some of the larger varieties may feel a bit cramped.
