I currently use 15 quart sterilites for the younger snakes until they reach 300 grams or so then its into a 32 quart they go. I'm currently drawing up a design for a rack that will hold 12, 60 quart tubs for the females (and one male who I don't want to put into a smaller tub long story) as they get older. Adult males should be just fine in 32 quart tubs, I'm putting my females into 60 quarts once they hit a certain weight. These are all sterilites that have the purple handles too.
