thanks everyone for your opinions. I've decided that I'm going to stick with the 2 that I have and leave it at that. I realize a rack and tub system is the best, but I enjoy having a tank that mimics the wild environment. They have plenty of space to hide, the entire tank is full of them. I built an acrylic top for it, and it helps me keep the humidity exactly where I want it, within 1 or 2 %, from room RH to 100%. The snakes really don't seem to be bothered, and aside for when she is preggo, both snakes always eat, and LOVE to eat. For now I'm going to stick with just these 2, but maybe one day I'll get the third and leave updates on here on how they are doing with feeding etc. Once again, Thanks for your help!
