Varieties of feed

Aquarium fish eat four main types of food, which must be combined or alternated regularly. When creatures get a varied diet rich in all the essential nutrients it needs, it has a beneficial effect on their health and even their attractive appearance.

You should be prepared for the fact that even fish have preferences, and some of them can feast on only protein or only plant foods.

Separately, mention should be made of those situations when skilled aquarists independently make dry or frozen food, which is difficult to attribute to one of the varieties. Alternatively, it can be chopped squid, shrimp and beef hearts, or microwave-dried cottage cheese or semolina.

In order for the fish to grow and develop, it necessarily requires vitamins of different groups, choline, folic acid, biotin, thiamine and other substances. In order to form an ideal diet for pets, it is necessary to find out how this species eats in natural conditions. Herbivorous fish have a long digestive tract and prefer to consume fragments of plants, seeds, fruits and, of course, algae.

Predators. the owners of a large stomach, they eat live or dead insects, amphibians, molluscs and even small animals. Finally, omnivores are ready to eat anything.

How to properly feed fish in an aquarium?

Properly organized feeding of fish in the aquarium is the key to their health and longevity. Although different underwater inhabitants have different requirements for the daily diet, the common thing is that it should be moderate and varied.

How often to feed?

You need to feed the fish in the aquarium a couple of times a day. in the morning and in the evening. Some aquarists put in more food in the morning than in the evening, but it is correct to offer absolutely equal portions to pets. The feeding schedule is built in such a way that once a week there is a fasting day, during which the pets do not receive food at all. This prevents the development of obesity, especially in those fish that have an increased appetite.

When spawning time comes, fasting days are canceled. Morning feeding is carried out a quarter of an hour after turning on the light, and evening feeding is carried out a couple of hours before bedtime. Catfish and other bottom-dwelling fish are usually fed in the dark when other inhabitants of the aquarium go to sleep.

It is impossible not to mention the feeding of the underwater inhabitants during long trips, for example, on vacation.

In fact, adults and juvenile fry are able to starve without problems for up to three weeks, and some species, which are large in size, even longer.

Alternatively, you can install an automatic feeder equipped with a dispenser in the aquarium, or purchase slowly dissolving briquettes and capsules.

Hand-Feeding Your Fish

How much to give?

Feeding your domestic fish should be done for a limited period. Experts recommend not feeding them more than feeding them excess food, which will further lead to obesity or problems with the gastrointestinal tract in fish. In addition, excess food disturbs the balance within the aquarium. Leftover feed begins to rot, which in turn pollutes the water and provokes harmful algae.

over, the composition of the liquid does not change for the better. the level of ammonia and nitrates rises. The amount of required food can be calculated depending on the weight of the fish. “lunch” should be about 5% of this indicator. After the meal, the leftovers will have to be caught with a net.


In fish, there are three ways of feeding, which are determined depending on the location of the mouth. In a general aquarium, it is still better to combine representatives of the same group, since this greatly simplifies the process of feeding them.

  • Upper. The upper feeding method is typical for fish in which the mouth is located on top. They consume food from the surface of the water, so it is more convenient to feed them with cereals or chips.
  • Middle. Those pets who prefer a medium-sized diet eat the food that is right in front of them.
  • Donny. Fish that prefer the bottom feeding method pick up food from the surface of the soil. In this case, we are talking, for example, about catfish. In order for the feed to reach the bottom, it is necessary to pick up heavy and quickly sinking pieces.


Carnivores have a characteristic large stomach, which indicates that food intake is large and rare (Figure 6). When kept in their natural habitat, carnivorous fish can feed on live or dead small animals, birds, insects, invertebrates and amphibians.

What do different types of fish eat?

Absolutely all fish differ in their food intake and behavior during feeding. Predatory fish species can arrange in some kind of ambush, while hunting for their prey, or freeze in anticipation of the approaching prey. However, other predators can pursue their prey in the desire to overtake and grab prey.

Herbivorous species primarily feed on living or decaying plant tissue. Aquarium fish get food by biting off parts of plants or can swallow them whole. However, among herbivorous fish, there are species that only eat algae.

How much can you not feed aquarium fish

The need for aquarists for summer vacations reflects the natural desire of a person to rest during the entire working year. However, during such periods, the aquarium must be left unattended.

Note: A properly equipped aquarium can do without human intervention for a certain period of time. Aquarium fish creatures are very hardy and can easily withstand a temporary non-receipt of feed.

Before leaving for a long time, you should not acquire new fish and plants (in order to avoid infection of the water space), fry and other small individuals. It is also worth reducing the dosage of food dispensed and completely eliminating foods that pollute the water from the diet. Fish eat only the portion they need, and the remainder will begin to spoil the quality of the water. It is imperative to clean all the aquarium equipment and refresh the water by replacing 1/3 of the total volume. It is not recommended to leave sick fish for a long time in the general aquarium.

Subject to these conditions, the fish can be left without feeding for 7-10 days, depending on the species.

Herbivorous species have a long digestive tract. Its presence confirms the need for frequent feedings, but in small portions. The diet of such breeds when kept in the natural environment consists of various algae, particles of fruits, plants and seeds (Figure 5).

It is precisely because of physiological characteristics that you need to know exactly how many times a day to feed herbivores, depending on their type and size.

Frozen feed

Very often, the sight of live food in the refrigerator causes not very pleasant sensations and emotions in people. An alternative solution to this problem is frozen food. They have the following positive aspects (Figure 3):

  • It is very easy to dose in portions;
  • Easy to store;
  • Do not deteriorate;
  • The composition is the same as that of live feed.

Types of frozen food for different fish species


It is not recommended to make food yourself, as they may not be sufficiently saturated with the necessary substances for the life of aquatic inhabitants.

Live food

Live food is very popular with fish and is considered one of the best. However, it is not necessary to feed the same species on a consistent basis, as the fish require a variety of diets. The most common types of live food are bloodworms, tubifex and corets (Figure 2). However, it has such disadvantages:

  • Diseases can be introduced into the aquarium;
  • Poison pets with a low-quality product;
  • Very frequent bloodworms are not recommended as they are poorly digested.

The simplest and most affordable disinfection for any aquarist is freezing, which can destroy some of the pathological microorganisms in it.

During spawning, live food is very necessary for fish. After receiving a good portion of any kind of live food, individuals are more willing to spawn. Fry raised on such a diet are distinguished by good health and strong immunity in the future.

Note: To date, there is a lot of information about the dangers of tubule, but this data is greatly exaggerated. The tubing can be cleaned by flushing 2-3 times a day for one week. After it has acquired a pink tint, it can be fed.

The tubing can be stored in the refrigerator on the bottom shelf, but it should be placed in a container with low sides and a small amount of water, which must be changed daily. Bloodworms should be stored between two napkins placed in a phytocuvette.

It is recommended to feed live food through special feeders, but do not store it for too long to prevent poisoning.

How to feed aquarium fish if there is no food

There are moments in life when a special feed has suddenly ended and you need to look for an urgent solution to the issue. However, there are ways to feed your pets by using the following tips (Figure 7):

  • Earthworms: The large fish in the aquarium are very eager to eat rain showers, but they must be thoroughly rinsed and chopped before dispensing. You should give the fish only the amount they need to completely satisfy their hunger.
  • Raw meat without streaks of fat can be eaten in the absence of live food. Raw meat should be scraped off with a knife and only in this form should be given to aquarium pets.
  • Cereals, especially buckwheat or semolina, as well as wheat porridge, are readily consumed by all types of cyprinids and labyrinth fish. However, such foods should only be given as a last resort. The groats must be cooked to a state of steep porridge, then rinsed under a stream of cold water and only with the disappearance of all the mucus, strain through a sieve. You can store it in any cool place.
  • Non-living food. It includes: dry daphnia, egg yolk, bloodworms (cut, dried and frozen), raw or dried meat, porridge, etc. You need to use such feeds with extreme caution, as they quickly decompose and begin to spoil the water.
