How to feed fish?

Feeding fish is simple once you know how. Just make sure that the dry food you are using is well suited to the fish species, as described below. Once you have found a food that works well and are feeding the fish the right amount, begin supplementing their diet with insects, vegetables, or other nutritious foods depending on the type of fish.
1.Research your fish species. People at the store where you purchased your fish should be able to help you pick out a fish food if you cannot find information specific to your species online. Find out whether your fish are herbivores, carnivores, or omnivores, and ideally the exact % of protein the fish species requires in its diet. Some exotic species require special diets, but most fish can be fed basic "fish food" flakes or pellet. However, don't go rushing to the pet store yet.
2. Find a fish food specific to your fish if possible. Many aquarium fish are fed with a general purpose fish food, or one intended for a broad category such as "tropical fish." As long as you read this section carefully, your fish may do fine with the right type of general food. However, if you can find a fish food specific to your fish species or group of related species, your fish will most likely be healthier and happier. These should be labeled clearly as "cichlid food," "betta food," etc.
3. Pick food that floats, sinks, or slowly sinks depending on your fish's mouth shape. You can ask an aquarium store employee for advice if necessary, but often watching your fish's behavior or mouth shape will be enough to find out what type of food to buy.
