Ok been doing some home work. I found some tubs that I think will work with a little engineering. I'm fairly handy as I've made most of my own melamine bp racks. However with the size and weight I am going to try my luck with pvc. I will be working with dumerils and Colombian boas so for adults would 60" x 36" x 12" be large enough tubs? as for new babies I'm planning on using 41 quart sterelite tubs. Probably over kill on baby tubs but I like giving them plenty of places to hide and regulate.
