When feeding your fish you should only feed as much food as the fish can consume in any two minute period. Once feeding has been completed there should be no food left on the surface of the water or floating around in the tank. If you find there is food floating around then you are feeding too much and need to net out this surplus food . Ideally, you want to feed your fish every day with a small amount to avoid excessive waste. Fish like humans require a balanced diet to stay healthy and retain an effective immune system. A good balance between flake food, frozen food and live food will provide all the nutrition they will need to grow and stay healthy and happy.
