Yes, thank you for the gravel tip. I did read that article after I added it, and couldn't remove it at work. I had a 10 gallon clear plastic storage tote with lid at home, so I cleaned it out and added some coconut fiber and top soil to it. I also added a little water dish, which I have caught him playing in several times lol, and a little hide out made from an old egg carton. He burrowed himself in for the night, and I had to search for him this morning. I went to PetCo and bought some crickets. He ate two, and I put the leftover ones in the fish bowl I bought yesterday, with some fishfood that came with it. So, hopefully, he continues to do well.
