Whether you’re feeding common goldfish, fancy Orandas or koi, Aqueon Goldfish Foods provide daily nutrition. Available in flakes or granules to accommodate the various goldfish feeding habits throughout the water column. Granules sink to the bottom of the aquarium faster than the flake variety and are sometimes preferred for larger fish that can accommodate a larger food portion. The color enhancing food formula has a higher concentration of ingredients that bring out the colors in fish such as: spirulina, marigold powder, chili powder, and more!
