From what I read, smaller often meals are better then one big meal once a week. My guy is 3 inches and he can down 2 large night crawlers or 4 super worms, or even 6 large crickets, lol. I do this feeding every couple days. So you probably could do about 3 crickets every couple days or even one large night crawler, or 2 super worms. It's up to you on how you want to feed him.
