i heard that the more coverage you offer your snake, the better, maybe think about getting some plants in there too, my corn loves the fake ones. real ones are dangerous, but the plastic plants you can buy at most pet stores are great and my snake spends all day in them. also, dont be alarmed if your snake spends all the time in one hide, it will be a baby and really shy at first, and you also might notice that the hide is over the heat pad or something nice for the little one.
good luck with your new viv!! can you post pix?
