I've heard its good to have two identical hides but I cannot find two quite the same. I have two hides that my snake fits into really really well; they are not identical but he doesn't know the difference. Is this ok? Is it absolutely necessary that they be entirely identical? If so, where does this logic arise from? I know in the wild they would find similar but not identical spots so I really don't see how that is necessary.
As far as water bowl, I have a young snake about 12-15 inches long and a 20 gollon tank. What size bowl should I get?
