King British Algae Wafers (with IHB) are an extremely palatable, complete, premium food made from high-quality, natural ingredients, including fish, molluscs and crustaceans. King British Algae Wafers (with IHB) have been specially formulated with our unique 'Immuno Health Booster' which strengthens a fish's natural immune system, providing a stronger shield against infection and disease, actively helping fish live healthy, happy lives. King British Algae Wafers (with IHB) are dark green discs which have been developed to quickly sink to the bottom of the tank and remain stable in the water for up to 3 hours, allowing bottom-feeding fish to take their time to eat the food. In addition, King British Algae Wafers (with IHB) have a high protein content of 45%, ideal for the metabolism of bottom-feeding fish, and a low waste formula for cleaner, clearer water. King British Algae Wafers (with IHB) contain added Vitamin A, C, D and E, and will provide your fish with all the essential vitamins, minerals and trace elements needed to support optimum health. King British Food is free from artificial colours, flavours and preservatives. Suitable for plecostomus, catfish and other algae-eating fish.
