Hello i will be receiving 4 07 babies from adam at 8ball soon and have some issues. First I originally thought I could put them in the same sweaterbox rack in 15 qt tubs and not take them out and that was quarantining. Well I wasn't aware I needed to put them in totally different tubs not near my existing snakes. Well I'm planning on ordering 4 tubs from reptiletubs.com. So what I need help with is the whole ordeal with setting up each tub. I'll order flex-watt from rich at reptile basics and get the appropriate size for each tub. But i'm a little confused as to how to stack all the tubs with the flex-watt under all of them. Do I weave the flex-watt through out the tubs just like they are in a rack system for belly heat?
