The flakes are small in size and usually float in the water. This gives time for the fish to eat them. Flake foods are usually fortified with minerals.
The size of the flake should be suitable for the fish. Small fish may not be able to eat large flakes.
Flake Foods usually come in sealed containers. They usually have a best-before date.
Store Flake foods in a cool dry place. Moisture and light should not be allowed to reach the flake foods.
