I had one for an undetermined amount of time - Very reclusive creature. I did nighttime feedings a couple times a week, dangling a piece of food in front of his cave. One day it just stopped showing up for meal time. I moved last year - no body / shell / etc was ever discovered. One of those cool/pretty critter if you're lucky enough to see it...I would look at something else, but that's just my two copper pieces.
