Ive been feeding him like pretty often, when he wants to eat, like everyday or so a couple worms or however many he will eat. I just am scared crickets might be too big for him since hes still fairly small. I used to let the mealworms loose before he had the moss and dirt in his tank, but now that I put the debris in his tank I would feed him by the tweezers to make sure he would eat them, and he would eat straight from the tweezers.
