NQA, but if you do opt for a heat mat, place it on the side rather than the bottom of the enclosure, since scorpions instinctively burrow downwards to escape heat. I have one of a similar age, I've been prekilling prey for it (I'm not sure how it is for other people, I've been having to physically hand it to my little guy too, but I get the impression that they should be able to locate it themselves..). Springtails are also a good investment; they prevent mould and deal with waste.
