And if anyone wants to know, we use the Sterilite 1996 (74 qt. 44x 19 3/4x 6 3/8) in the rack my hubby built. We have Iris tubs in the hatchling rack Neil Golli sold us, I do favor them because they are nice and smooth on the inside...although its a hatchling rack with one baby in it so it hasnt had the chance to get dirty yet. Havent had any problems with the Sterilite yet....although we have only had the snakes racked for about a week now.
