One starter culture of peanut beetles. Can start feeding immediately out of the starter culture. You feed the larva not the beetles just like mealworms. They resemble mini mealworms, except they have a soft outer shell. One of the most nutritional live food you can feed your fish. Great for fish of all sizes including fry all the way to larger cichlids. Great for conditioning your fish to breed or speeding up the growth of juvenile fish. This is a true set it and forget it live food with minimal care to produce your own, live fish food. Peanuts and oats are all that is needed to feed your culture. One to two times a week is the recommended feeding.
