To use this GloFish food, simply sprinkle a small amount into the aquarium once or twice a day, depending on the number of fish. Make sure not to overfeed, as uneaten food can dirty the water. Keep the food in a cool, dry place to maintain its freshness. Check the water quality regularly, as a clean environment is important for your fish's health. If you notice any changes in your fish's behavior or appearance, adjust the feeding amount accordingly.
