Fish also need to have a varied diet in order not to become bored with the same old foods and to avoid becoming addicted to one food, which is undesirable. It is important to offer foods of appropriate size. It is no good feeding tiny flakes of food to a great big fish, just as feeding large lumps of food to a tiny fish is useless.
Generally you should feed your fish two or three times a day with very small helpings - unless they are large carnivores, in which case they will need special requirements and these are dealt with individually later onion the hook. If you are feeding flake food, then give them only a very
small pinch and check that this is all eaten within three to five minutes .Healthy fish are hungry fish. If your fish are always at the surface looking for food, or if they rush to the surface when you approach the tank, then that is a good sign. If you are giving your fish the messier foods, such as blended meats or raw fish, then this should all he consumed within a minute or it will pollute the tank. A quite common practice is to 'fast' the fish for one day a week. This ensures a better appetite and the fish will not be harmed; in their natural state they can go weeks without food.
