Types of fish living without oxygen

I would like to note that there is not a single living creature that can continue its vital activity without air. However, among the aquarium fish there are such representatives who can not breathe oxygen dissolved in the aquarium water, but receive it from the atmospheric air. Macropod, loachwinds and labyrinths are able to catch air from the surface of the water and keep it in their body for some time.

How much can live without air

In the previous section, we found that no living organism can exist without air.

If the inhabitants of your aquarium are representatives of the species discussed above, then do not worry. They are adapted to living in water without aeration.

However, there are many fish that need oxygen in the water, otherwise they will not survive. Sometimes it can happen that the lights are turned off, the instruments in the aquarium do not work. There is a logical question. how many such fish can survive without air.

How many fish can be settled

This question is difficult to answer unequivocally. An important role is played by both the size of the aquarium itself and the size of the pets. The larger the fish, the greater the volume of water should fall on one individual. For example, for a fish 5 cm long, 2 liters of water is enough. If the fish is 8–10 cm, then about 5 liters are already required. For large individuals, the size of which is more than 12 cm, you need about 10 liters of water for each.

However, there are many exceptions to this rule. If you have a low and wide aquarium, then the number of fish can be increased, because the water in it is better saturated with oxygen. If you plan to start any of the labyrinth species of fish, then the population density can also be increased. But if you want to breed goldfish, then they will be more comfortable if more water comes to each individual, since they produce a lot of waste.

If the fish are not mobile, then the water per pet is required less than on the active, many moving fish.

Filtration and the presence of a compressor also affect the number of fish in an aquarium. If you have all the necessary equipment, then the number of fish can be increased, because the water in such an aquarium is cleaned, and the air is saturated with oxygen.

The shape of the aquarium is important. Many prefer round aquariums. Indeed, they are beautiful, fit well into the interior. But, It should be borne in mind that not all of them can be equipped with the necessary devices. For example, a small round aquarium, measuring about 5 liters, made in the form of a glass, is not very suitable for permanent residence of fish. It is better to use it for temporary jigging.

In general, such types of fish as catfish, Betta Fish, and lyalius are best suited for round aquariums. The density of their settlement must be considered based on the characteristics of the fish. In addition, do not forget that in the aquarium there are not only fish, but also soil, algae. Thus, the volume of the aquarium should be deducted 10-15 percent, and only then count the number of individuals.

Schooling fish require more water, so you should keep them in large aquariums. Aggressive fish also require a lot of space.
