Many novice aquarists seek to reduce their financial costs of the aquarium. Indeed, the equipment of aquarium aeration and filter requires certain cash. In addition, these devices need to be careful, to clean them in time, so that they did not fail. In this regard, many are faced with a question, there are fish that can live without oxygen.
Types of fish living without oxygen
I would like to note that there is not a single living being that can continue its livelihood without air. However, among aquarium fish there are such representatives who can breathe non-oxygen dissolved in aquarium water, but to obtain it from atmospheric air. Macropodovy, beliefs and labyrinths are able to grab the air from the surface of the water and hold it for a while in their body.
Businesses can gain air into the intestines. One of the bright representatives of such fish are Somi corridors. This small fish is about 3-7 cm. On the back of them there is a shell from bone plates. The most common color is gray-olive. These are peaceful fish that get well with other representatives. They love to hide in shelters, often roll the soil in which they are looking for food.
There are about 150 species of corridors. Most common are common as golden, crawled, panda, sand, adolfi, leopard, Venezuell.
The average life expectancy of this type of cattle is 10-12 years old.
Macropodic and maze of fish have a special gills device, which also allows them to fit the air from the surface. Consider the most unpretentious and common representatives.
Gurura
Peaceful fish, the size of about 5-12 cm. Selects a lot of varieties: pearl, lunar, blue, kissing, grumbling, marble, gold, chocolate. The names of the species speak for themselves - in coloring these fish are diverse.
These are very unpretentious in the content, peaceful in relation to other inhabitants of the aquarium, playful fish. A good option for a novice aquarist.
From general recommendations, you want to highlight the following. The aquarium must be at least 50 cm long, but at a volume of at least 50 liters. Fish need space for shelters and games. In eating, they are unpretentious, eating different types of feed, however, it is important not to overpaying them. For spawning, they need floating plants.
Lyalius.
Small fish, about 7 cm. Pugliva, it is best to start a pack of minimum of 3 fish. May live even in a small aquarium with a volume of about 10 liters. However, for comfort, it is still better to purchase a rarative container. Well gets around where there are a lot of algae, vegetation, because they love to hide.
It is not recommended to put an aquarium in a noisy and brightly lit room, since the fish data is afraid of loud sounds and sharp light. In eating unpretentious.

In the aquarium, vegetation must be present, so that the females were where to hide during spawning, as well as from the aggressive male.
Labiosis
These are large quiet fish. They need a minimum of 10 liters of water per resident. Very fond of algae. From the feed prefer fine, diverse. Particular attention in their breeding should be given to the temperature regime in the aquarium. Comfortable for them is the temperature + 25-28 degrees.
McOuropodes
Still fish that can live even in a three-liter bank. They carry cold and spoiled water. Macros of Dracle, do not like smaller neighbors. In eating unpretentious, omnivores. For the soil it is better to use clamzit, large sand.
It is not recommended to place narrow decorative elements in aquarium, since the fish can be stuck and die.
The aquarium should have a lid that does not overlap access to air. In addition, the ideal option will be if the surface of the water is covered with algae.
Akantofthalmus
This fish is satisfied complex in care. They prefer small aquariums. Shelters are needed - stones, squals, castles. Such fish can jump off, so open aquariums are unacceptable. It is difficult to breed them even professionals. Food can be content with the microorganisms from the soil and the waste of the rest of the population of the aquarium, however, will be glad to live and ice cream treatments.
Plug ordinary
Such a fish is called a home barometer, since its restless behavior predicts the onset of bad weather. They are unpretentious, can live in aquarium from 10 liters. There are no special requirements for temperature, it can vary from +3 to +30 degrees. Soil can be both large and small. It is not recommended to use sharp decorations aquarium.
In general, there are many fish, which is optional for vital activity with aquarium filter and aeration. Consider the size and nature of the pets, as well as the water temperature, the quality of the soil, and then the fish will coexist together.
How many can live without air
In the previous section, we found out that no living organism could exist without air.
If the inhabitants of your aquarium are representatives of the species discussed above, you can not worry. They are adapted to accommodation in water without aeration.
However, there are many fish that require oxygen in water, otherwise they will not survive. Sometimes it can happen so that the lights turned off, the instruments in the aquarium do not work. There is a lawsager question - how many such fish can withstand without air.
There is no unambiguous answer. It all depends on the population of your aquarium, the presence of vegetation in it.
If the norms of water per fish are observed, the aquarium is not overcooled, there are living plants in it, then it is possible to say with confidence - several hours of fish will definitely live.
Live algae produce oxygen, which, although in a lesser extent, than special devices, saturates water.
How many fish can be settled
This question is difficult to answer unequivocally. An important role is played both the size of the aquarium itself and the size of pets. The larger the fish, the greater the volume of water should have to one individual. For example, for fish 5 cm long enough of 2 liters of water. If the fish is 8-10 cm, then about 5 liters is already required. For large individuals, the size of which is more than 12 cm, you need about 10 liters of water for each.
However, from this rule a lot of exceptions. If you have a low and wide aquarium, then the number of fish can be increased, since it is better saturated with oxygen. If you plan to make any of the maze varieties of fish, then the settlement density can also be increased. But if you wish to breed goldfish, they will be more comfortable if there will be more water for each individual, as they produce a lot of life waste.
If the fish are sediments, then the water per pet is required less than active, many moving fish.
Filtering and compressor presence also affect the number of fish in the aquarium. If you have all the necessary technique, then the number of fish can be increased, since water in such aquarium is cleaned, and the air is saturated with oxygen.
The form of aquarium is important. Many prefer round aquariums. Indeed, they are beautiful, fit well in 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, about 5 liters, made in the form of a glade, is little suitable for permanent fish living. It is better to use it for a temporary leaning.
In general, for round aquariums, such types of fish are best approached as catfish, cocks, Lyalius. The density of their settlement should be taken into account on the basis of the characteristics of the fish. In addition, do not forget that in the aquarium are not only fish, but also soil, algae. Thus, from the volume of the aquarium, it is necessary to subtract 10-15 percent, and then calculate the number of individuals.
Benefish require more water volume, so they should keep them in large aquariums. Aggressive fish also require a large space.
Talking aquarium, try to have the inhabitants of all the layers.
It is easy to define them: if the mouth is flown up - the top layer is located exactly - the middle, looks down - the bottom.
Given all these recommendations, you can create a real ecosystem in your apartment, which will be comfortable to all its inhabitants.
How to care for aquarium
Aquarium care involves regular washing of the filter sponge. We can not use detergents, it is only water. In addition, it is necessary to purchase a siphon for the soil and with it to clean. Aquarium care involves partial water replacement.
If your aquarium is not equipped with a filter and aeration, it needs special care.
It follows the water in it more often than in equipped devices. On average, this procedure is performed 2-3 times a month. 20-30 percent of water is removed from the aquarium, and pure, spilled water is poured into its place. It is impossible to pour water from under the tap, fish may die. It should be standing for 2 days.
