Crickets are one of the easiest foods to feed your fire-bellied toad. They are inexpensive and available at most pet stores. They come in a variety of sizes, so be sure to choose a size that is small enough for your toad to eat without difficulty.
Gut-loading the crickets (feeding them nutritious foods prior to giving them to your toad) is a good option that will help to easily add more nutrients to your fire-bellied toad’s diet. Wheat germ and oatmeal are good gut-loading options, as are powdered instant baby cereals. Nutritious vegetables are also good to include, such as kale, collard greens, mustard greens, and dandelions. Since fire-bellied toads maintain their bright colors by using the carotenes in their food, it is smart to also feed the crickets some bright red and orange fruits or vegetables, like carrots, oranges, or beets.
Mealworms, waxworms, silkworms, fruit flies, black worms, tubifex worms, bloodworms, guppies, and shrimp are also good options. Try to give some variety in his diet, as this is the best way to get close to mimicking what your pet would eat in the wild. No matter what you decide to feed your fire-bellied toad, you should feed at least once every other day, preferably daily, during daylight hours. Fire-bellied toads rarely become obese, but monitor your toad closely to make sure he isn’t losing or gaining too much weight. Also, if his color dulls or fades, try adding some additional carrots and sweet potatoes into the diet of the gut-loaded crickets.
