Chibi is on a diet of dusted crickets 2-3 times a week, and mealworms on all other days. She's steadily gaining weight but I was wanting to vary her diet a bit. I saw on an info slip at the petstore that leos eat crickets, wax worms, mealworms, and....fruit?

Do leopard geckos eat fruit? If so, what kinds? Also, a friend recommended nightcrawlers as a treat every other week or so. I know that leos like roaches, but I can't have those for a long time, so those are off the menu. Other than pheonix worms, crickets, wax worms, and mealworms, what can you feed to leos?
