I have 11 of these guys (8 babies yesterday) and they're awesome! I keep mine on shredded aspen, that I get giant bags for 15$ online. It works because I breed my own mice too. All of mine (except the babies) eat fresh-kill and live. I have a mature breeding pair and a sub-adult female. The sub-adult will eat fresh kill small hoppers/large fuzzies, but she sometimes gets pinkies too, which I just feed live. The adult male will do large fresh kill hoppers/small adults, but the adult female prefers smaller prey, so she'll eat the same size as the sub-adult. I keep my breeding pair in a modified 15gal. It would be 15 gal, but it's only half the height since they're burrowing snakes. I am able to take mine out to feed them. The male goes off feed sometimes, but the females always eat good.
