That looks interesting Steve, but I'm sticking with crikets, mealworms and the occaisional waxworm treat for now. I haven't fed him mealworms yet, but plan on buying them--quantities of 50, gut loading for a day or two, then refrigerating them. He's been eating 5-7 crickets/day. He shed about a week ago when I brought him home.
I have ceramic tile in the tank now with two hide rocks like the ones you have--one on the warm end and one on the cool end. I don't have anything under these rocks right now, but plan on putting damp paper towels under them and changing them frequently during the shedding process.
He seems very happy overall, is eating well (though sometimes ineptly!) and is really good about being handled (only about 5 minutes/day).
