King Brtiish Goldfish Floating Food Pellets are a complete food, ideal for larger coldwater fish. The pellets are 3mm to 4mm across and are water-stable, meaning they remain as enticing mouth-sized chunks rather than dissolving. They are designed to float just below the water surface for several minutes so that they are readily accessible to surface feeding fish. Contain pre-biotics to aid digestion, and 37% protein.
