So what I have found out for you is they do like damp substrate do not have it soaking wet though, if you take a handful and squeeze it, it should feel wet but no water should be dripping from it. Also they like to burrow, like a lot, so it will definitely need more substrate. I can also confirm that these guys do prefer it cooler, what are the current temps of you're room as they could be fine, anything from 64 to 72 is sufficient.
