"I feed our fish a variety of food, but the Hikari bloodworms are the food that every one of our fish eats the fastest and with the most excitement. I've had success feeding it to our oscar when it was still small enough to be satisfied with such small food, my betta, our African cichlid, catfish, goldfish, loaches, and even our plecostomus goes to surface, occasionally swimming upside down so I can drop some straight into its mouth. Not only do the fish love it, but it is very high in protein and is fortified with C, E, and B vitamins."
