Food for aquarium fish at home.

It is very important to know the diet of each species so that you have an adequate diet with all the nutrients and vitamins.

Fish eat differently when they live outside their ecosystem. In their natural environment, these animals usually hunt and eat other smaller aquatic creatures., such as larvae or other invertebrate species. In most cases, typical fish are carnivores. However, they may also sometimes feed on plants or other types of algae. The situation changes markedly when we move these animals into aquariums, and their diet varies depending on the species and habitat: freshwater, marine, tropical or demersal fish.

It is important to know the diet of each species in order to provide them with adequate food containing all the nutrients and vitamins they need to stay healthy and live for many years. As in all areas of life, fish food can be purchased or prepared independently. If you make it yourself, you will save a significant amount of money, plus you will probably feed your fish better.. Below is all the information on how to prepare homemade fish food:

What do fish eat?

It depends on the type of species, e.g. Cold water fish are very easy to care for and feed. The use of flakes and granules is highly recommended.. We can also give them fresh foods such as shellfish meat, protein-rich worms and raw meat or fish, avoiding those that contain too much fat or blood. It is highly recommended to consume fish eggs and vegetables such as spinach or lettuce.

Tropical fish feed on living and dry organic matter., such as mosquito larvae, shrimp or small worms. We can also serve them cereal or kibble that provides them with nutrients, protein or fiber. However, bottom fish cannot eat foods with scales. Try giving them round tablets and discs because they are the most used food for these species.

Homemade food ingredients

Now that we know what these pets eat (or usually eat) in general, These are the ingredients from which you can prepare homemade food suitable for all types of fish. what we have in our aquarium. It will take you little time, you will feed your animals well and, as we noted earlier, you will save a large amount of money, in addition to food for at least two weeks.

To prepare it we will need the following components:

  • Half a kilo of fish meat without scales
  • Half a kilo of beef liver and beef heart, which should be added without fat and nerves.
  • sweet paprika
  • boiled egg
  • Carrot
  • beet
  • Lemon juice
  • Head of peeled garlic
  • Four tablespoons of rolled oats, two of a multivitamin and one tablespoon of soy lecithin, plus a quarter tablespoon of sodium benzoate and one glycerin for hydration.

From these materials we can prepare homemade food for our aquarium pets:

  1. Once all the ingredients are mixed, we will start grinding until we reach a consistency typical of porridge, to which we will have to add water until we get a semi-liquid liquid.
  2. From here, a tray on which you can spread the porridge in a thin and even layer until it is covered will be very useful.
  3. After this, the next step is to place it in the oven at a low temperature, not exceeding 100 degrees, so as not to destroy the vitamins that are in each of the nutrients.
  4. As soon as the moisture of the porridge has dried, we begin to remove it from the oven, using a spatula and trying to prevent the food from sticking to the baking sheet. If it is not possible to remove it because it sticks too much, we recommend leaving the porridge in the tray outdoors overnight to allow the ambient moisture to act and seal the food from the tray.

The amount of ingredients varies depending on the needs and number of fish living in our aquarium. If our fish are more carnivorous, we can reduce the amount of vegetables.. If the fish are more accustomed to plant nutrients, they will have to be increased.

Some fish develop eating disorders when transferred to aquariums. If this happened, It is recommended to stimulate appetite with a vitamin complex., which we can get from a pharmacy or a veterinarian. Before purchasing, you should consult with a specialist.

How many times a day should you feed your fish?

Most of the time, people feed their fish at least twice a day; one in the morning and one in the afternoon. This is incorrect because we should be modeling the timing and amount of food they would eat if they were in their natural state. The best thing to do would be to provide them with food in small quantities four to six times a day.

To feed your fish, you need to imitate their natural state.To feed your fish, you need to imitate their natural state.

It is very important to control the quantity so that they do not die from overfeeding. Otherwise, the fish may become infected with diseases, pollute the water, and even die. The quality and sufficient quantity of food we give him will determine his good growth and development. A pinch of food will be enough. As much as possible, you should try to get all the fish to eat more or less the same thing.

How long can a fish go without food?

The length of time these pets can go without feeding depends on various factors: the species, their health, the care they have received since leaving their natural state, the quality of the water they live in, and the diet they have consumed. , etc.

However, we can get a rough idea. Assuming the fish are in good condition, they can survive without nutrients for two to three days.. After this time, the animal may feel some weakness due to loss of protection. If this happens, the fish may develop health problems and become infected with various diseases.

Fish can go without food for 2-3 days.Fish can go without food for 2-3 days.

Some rumors are passed down by word of mouth, suggesting that the fish can go without food for up to a week. This may or may not be true, but it is very difficult to achieve. When fish need to eat, this can be seen in their behavior, as they tend to be more restless than usual and rise to the upper layers of the water in search of food. It is likely that their skin and scales will lose their shine and color and become damaged.

Caring for aquarium fish

Food is not the only element that we need to take care of to feed our pets. Aquarium, lighting and water are other factors that should not be neglected. after all, the more the natural habitat of these species is imitated, the better. We can use lighting to play with temperature. If it is very lit, it will affect the temperature of the water, which is very important for these animals. Playing with light and dark will allow us to create a variety of environments in the aquarium, and the fish will decide which one to choose.

Water is also important, to say the least. Tap water is not the best for fish as the chlorine can directly affect their gills. We have to adjust the pH of the water and change it often. If we do not have the basic knowledge about the type of fish and water that each species should have, we must seek the necessary guidance from people who know and have experience keeping these animals.

There are many recommendations for aquarium fish.There are many recommendations for aquarium fish.

It is recommended to use biological water filters as this allows existing waste to decompose. Gravel can also be used as a filter and also helps to properly preserve plants in aquariums.

It is very important to know that Cold-water fish cannot coexist with tropical fish.and if we have both species, we must separate them into different aquariums with colder water (for cold-water fish) than for others (tropical). The same goes for marine and freshwater fish.which obviously cannot survive if we place them in another type of water to which they belong by natural origin.

Finally, pay attention to swim bladder disease. We see our fish suffer from this when it swims face up, appears clumsy and does not move naturally, or when it collides with objects around it, as well as many other symptoms. Sometimes, This occurs as a result of several reasons such as improperly maintained water conditions, viral or bacterial infections, sudden changes in temperature.or, in some species, poor nutrition may result in the bladder being unable to inflate and deflate as the fish wishes.


The health of our fish starts with a suitable place to live, the right water quality and proper nutrition. Cold-water fish are easier to keep as they usually have a large appetite., although this does not mean that you can feed him anything. As an animal species, they need a diet that is suitable for their digestive system. On the other hand, tropical fish food should contain sufficient amounts of proteins, fats and vitamins that you would take if they were in their natural habitat.
