When you purchase a frog from a retailer they will give you options of food for your frog. More than likely they will suggest you feed your frog crickets, mealworms, insects and larvae. There are also powdered vitamins that you can supplement with. Something to remember is that when you feed your frog it should consume all food within 15 minutes. If it does not, then you are overfeeding and should cut back the amount at a time.
