San Francisco Bay Brand Bloodworms Freeze-Dried Freshwater Fish Food is a popular high-protein treat consisting of freshwater bloodworms that have been freeze-dried for convenience. These small, reddish worms are irresistible to many aquarium fish, including bettas, gouramis, tetras, and other tropical species. Offering freeze-dried bloodworms is a great way to entice finicky eaters to feed, as they retain the natural flavor and nutrients of live bloodworms without the risk of parasites. Use them as a nutritious snack or to supplement your fish’s staple diet – they promote growth and conditioning, and their lightweight texture allows fish to easily nibble them from the surface or mid-water. Available in Multiple Sizes
