Red mosquito larvae or "bloodworms" are a wonderful natural food source for betta fish, discus, eels, angels, gouramis, platys, swordtails, tetras, barbs, and most community fish. Because they are freeze-dried they will maintain their shape, making them more appetizing to picky eaters. With no filler or additives, 100% freeze-dried bloodworms retain their flavor and most nutritional content, and will last as long on your shelf as it takes for your fishes to gobble them up! A great regular supplement for any freshwater carnivore or omnivore staple diet.
