How to feed aquarium fish properly

how to feed fish

To have a healthy and successful Aquarium, you have to feed the fish a correctly. Find out how.

Feeding is one of the most important things to do regularly in the aquarium. In principle, feeding is quite simple, but you can do a lot wrong. The wrong feed can lead to deficiency symptoms, for example, and too much food can lead to nitrite poisoning or an algae problem.


The following things must be observed when feeding:

  • Frequency of feeding
  • Time of feeding
  • Feed type
  • Feed size
  • Feed amount

Make sure you have the right kind of feed

There are 3 types of nutrition that differ fundamentally. It is best to keep fish with similar eating habits together. Each type of diet prefers certain types of food.

Carnivores / Carnivores

The carnivorous species include fighting fish and many species of perch. It is very difficult for carnivores to digest plant foods. For feeding carnivores, protein-rich live and frozen food is particularly suitable, and for some species also meat-containing dry food . Normal dry food has a high proportion of vegetable ingredients and is therefore unsuitable.

  • meat-containing, protein-rich dry food
  • Live and frozen food such as Artemia, mosquito larvae and water fleas

Herbivores / herbivores

Herbivorous species have longer and more complex digestive tracts than carnivores. In addition to dry food with plant-based ingredients, you can also feed fresh green food such as zucchini, cucumber or lettuce . Herbivores often make use of the algae growth on decorations and plants. Many species of catfish belong to the herbivorous species. Some herbivores now and then also eat meat containing food.

  • fresh green food
  • Live and frozen food such as Artemia, mosquito larvae and water fleas

Omnivores / omnivores

Omnivores feed on both vegetable and animal foods. Often, however, omnivores have a preferred diet. In the case of omnivores, it is particularly important that the feeding is varied and that both vegetable and animal food is offered.

  • mixed dry food with vegetable and animal ingredients
  • fresh green food
  • Live and frozen food

Make sure you serve them the right feed size

In addition to the type of feed, a feed size that is appropriate for the mouth is important. It is self-explanatory that small fish, such as neon tetra, cannot eat huge flakes. Big fish like angelfish, on the other hand, find it too time-consuming if they have to pick up food that is too small. For small fish, granules are suitable as dry food and Artemia as live or frozen food.

For larger fish, flake food is suitable as dry food and live and frozen food, such as mosquito larvae or earthworms. For bottom dwellers with a downward-pointing mouth, such as catfish, food that sinks quickly, such as food tablets, should be used.

Make sure you feed them often enough but not too much

The frequency of feeding is another important factor. Many beginners tend to feed too much and often. For most species it is enough to feed them once a day. An exception is young fish, which should be fed at least 3 times a day. You can stop feeding once or twice a week and introduce a day of fasting.

Make sure you consider the time of feeding

When it comes to feeding, there is generally little to consider. In nature, fish do not always get their food at the same time. In principle, it doesn’t matter whether you feed your fish in the morning, at noon or in the evening. However, it is important that the aquarium is illuminated for at least 30 minutes before and after feeding.

Make sure you have the right amount of feed
