Okay, sorry for the delay! I honestly forgot i posted this. When i say rack i dont mean tub rack. Its more of a big wire shelf and one is on the top shelf and one is on the bottom. They both have dome heaters, so ones conditions are not affecting the other one. I will never try and breed them. I dont want to breed them either, nor will they ever meet. The question was just out of curiosity but that would make a pretty snake!
