Using this NorthFin Carnivore Formula fish food is easy. Just sprinkle the appropriate amount of 10 mm slow - sinking pellets into your aquarium according to the number and size of your carnivorous fish. Don't overfeed; a good rule is to give only as much food as your fish can consume in a few minutes. Store the fish food in a cool, dry place away from direct sunlight to maintain its quality. Make sure to seal the package tightly after each use to prevent it from going bad. And always keep an eye on your fish's health and adjust the feeding amount if needed.
