What fish can live without oxygen and filter

Many fish intended for keeping and breeding in captivity, can not do without oxygen and filter. But not all! There are wonderful aquarium fish that freely do without an aerator. Name them - betta, or cockerel.

The question "opened a pet shop. Business is not going. What to do?" - 2 answers

Instruction

1. The main advantage of these fighting fish is that they can live without oxygen and a filter. The fact is that cockerels breathe atmospheric air. Moreover, they do not even like to live in an aquarium equipped with a filter, since such a “dwelling” is oversaturated with oxygen, and the current created by the compressor only scares them. Of course, one should not argue that cockerels can live well in three-liter jars, but the fact that they feel great in a small aquarium without any filtration and aeration is an indisputable fact!

2. That's just the breeding of these fish can cause some difficulties, and not everyone wants to become a professional breeder. Many people generally keep cockerels for enjoying their beauty. The cockerels are not whimsical in the rest of the service: they feel great in stale water, and also have no increased appetite. However, this does not mean that the males need to change the water every six months and feed them once a week. Not!

3. Betta aquarium fish (or cockerels) are members of the labyrinth family. It is no coincidence that these fish have been christened "cockerels". The fact is that their color and combative fighting character reminds of beautiful and cocky cocks. For example, if you put two betta males in one aquarium, then a real cockfight with loose fins and tails can begin. If time does not separate the "fighters", then one of them will die.

4. In general, cockerels are descended from Vietnam, Indonesia and Thailand. There they live in warm and small reservoirs with stagnant and silted water. That is why an aerator is not needed for saturating an aquarium with cockerels. Males have an oval body, elongated in length and slightly compressed at the sides. The length of the calf of males reaches 5 cm, and in females it is 4 cm. Dark stripes are arranged along or across the body of the males. Upper fin has a rounded shape. The bottom starts from the head and comes to the tail. The pectoral fins of cockerels have the correct pointed shape.

5. It is believed that the beauty and uniqueness of color is not equal to these fish. The males are motley, and their colors shimmer from red to pink, from pink to yellow, from yellow to orange, from orange to green, taking all sorts of shades. Especially bright color can be observed in males, arranging a "cock" fight. It is curious to watch the fish even when they inflate their gills in an excited state, forming a kind of bulging “collar” around their heads.

Do I need a filter in the aquarium

For the aquarium to delight the eye, and its inhabitants are always healthy, it requires careful maintenance and the use of special equipment. One of the required attributes of a densely populated aquarium is a filter.

Aquarium without filter

Is a filter always necessary in an aquarium? No, if there are few inhabitants and there are about 10 liters of water for one fish up to 5 cm in size. In this case, biological balance will be established in the aquarium even without a filter, and with regular removal of debris accumulating at the bottom of the garbage and a weekly change of 1/10 of the water, the fish and plants will feel quite good.
In an aquarium without a filter, there must be aeration, it contributes to the saturation of water with oxygen and the oxidation of harmful substances. If the population of the aquarium is large, a filter must be provided.

Aquarium Filters

There are several types of filters used by aquarists. The simplest is a foam sponge, put on an air dispenser. The rising bubbles cause a weak flow of water through the sponge, particles of debris are deposited on its surface. From time to time the sponge should be carefully removed and rinsed.
Another option filter - air-lift. The principle of its operation is as follows: the air diffuser is placed in a tube with a diameter of 1-2 cm. The lower end of the tube is located at the very bottom, the upper end is displayed in a small cuvette located above the water surface at the back wall of the aquarium. A number of small holes are drilled in the bottom of the cuvette, they are covered on top with a small plastic mesh on which a layer of sand 1-2 cm thick is poured.
When aeration is turned on, the water along with the air flow through the tube enters the cuvette. In it, it passes through the sand and drops through the holes in the cuvette into the aquarium. Such a filter has several important advantages: first of all, it purifies water very well. Cleaning takes place both mechanically, due to the passage of water through the sand, and as a result of the appearance of bacteria in the sand, which decompose harmful substances. From time to time - for example, once a week, this filter is washed. Namely, accumulated debris is removed from the top, once every few weeks you can change the top layer of sand.
Such a filter will be even more effective in combination with a bottom filter. In this case, a sheet of plexiglass with a lot of small holes drilled in it is placed on the bottom. In one of the corners in the sheet a hole is made for the airlift tube. Lining is placed under the sheet so that there is a distance of at least 1 cm between the bottom and the sheet. The lining should not impede the flow of water and can also be made of pieces of plexiglass.
A fine plastic mesh is laid on the sheet of plexiglass, the ground is poured on top. When working airlift water comes from under the plastic bottom, with all the soil acts as a filter. Such a filter not only perfectly cleans the water, but also promotes the growth of aquarium plants.
There are external external filters that provide very high quality cleaning. Water can be supplied not only by airlift, but also by a special pump. In stores, you can buy factory filters of any type, both internal and external. The choice of a particular filter is determined by the population of the aquarium and the preferences of the aquarist.

What aquarium fish live without oxygen and air


WHAT FISHES LIVE
NO OXYGEN
At first, I would like to make a reservation right away. All life on earth can not live without oxygen, or rather without air. Therefore aquarium fish that live without oxygen simply do not exist, there are only fish that, with the help of special organs (gill labyrinth or intestinal respiration), can breathe atmospheric air, and not oxygen dissolved in water.

And so, the fish breathe oxygen, which is contained in the water. This happens with the help of a special organ of respiration - the gills, which in turn come in various shapes. As a rule, the gill slits are located on the sides (about 4-5 pairs of gill lobes). The water washing and passing through the gills gives up the oxygen dissolved in it and carries away the carbon dioxide that has been emitted. Next, the "extracted" oxygen is spread throughout the body of the fish.

However, some species of aquarium fish can breathe skin or take in air into the cavity of a floating bladder. In addition, there is the so-called intestinal breathing, which is possessed by aquarium catfish (speckled catfish corridoratus) and loachworms, which can get air into the intestine with the help of the anus. I think that all those who have speckled catfish have seen how they rise from the bottom of the torpedo to the surface of the water and back - this is exactly the same thing - intestinal breathing!

And now we are getting to the question that interests us! Some species of fish have special organs with which oxygen is absorbed. One of these organs is the gill labyrinth, whose owners are classified as LABYRINTH FAMILIES. A labyrinth is a specialized respiratory organ that allows you to absorb oxygen directly from the air. Labyrinth fish take the air by "swallowing" it from the surface of the water. Therefore, such aquarium fish aeration is not needed! However, if access to the surface of the water is closed, such a fish will soon die.

What kind of labyrinth fish can live without oxygen, here they are:

Cock, Betta or Boytsovskaya fish

In Asia, a lot of rice fields and it is there that live fish adapted to breathing atmospheric air. These are, in particular, labyrinths that have a labyrinth labyrinth organ (labyrinth). It consists of winding canals, the walls of which are formed by bone plates covered with films with blood vessels. Contract labyrinth enters the perch-shaped detachment.
The labyrinth organ makes it possible to survive in water, where there is practically no oxygen. Moreover, if labyrinth fish interfere with breathing air, it will die even in oxygen-saturated water. Therefore, keeping such fish in an aquarium, it is necessary to ensure that floating plants do not completely cover the surface of the water. And there is also the African labyrinth fish - Ktenopoma.

Bottom filter for aquarium

The bottom filter is a whole water purification system that is used in aquariums of various sizes. Its main principle is water filtration in a natural way, that is, through the ground. However, there are many questions and disagreements about this method, because the main garbage remains on the surface of the ground, so it has to be periodically washed. So, we will consider everything in order.

Bottom filter design

This type of filter is an unusual system. It consists of

  • lattices with small cells (either from a thin plate with small holes),
  • pumps
  • tube systems.

The tubes are located at the bottom of the aquarium, the grid or plate is placed on top, and then a layer of soil.

It should be noted that in this case it is impossible to apply sand and shallow soil, because it will clog the holes through which water is circulated. At installation of the bottom filter small pebbles or small pebbles are poured on top.

How does the bottom filter work?

The principle of operation is very simple:

  • the pump drains the water out from under the grate,
  • then it is cleaned through a special filter element and returned to the aquarium;
  • then the water re-seeps through the ground, undergoing a rough cleaning, and the process begins anew.

In the tubes, which are located at the very bottom (under the plate), there are small holes through which water is drawn. Optionally, you can optionally install a tube with an aerator. Thus, not only the filtration, but also the aeration of the whole soil will be carried out.


Advantages and disadvantages

Before installing the bottom filter should be familiar with its features. Of course, the first minus will appear immediately. To install the system, it is necessary to completely drain the water from the aquarium, remove the soil and all the decorative elements, which takes a lot of time.

The indisputable advantage of such a filter is:

  • continuous circulation of water from the entire aquarium;
  • when passing through the soil, it stagnates at the bottom;
  • Such a water cycle allows you to avoid rapid contamination of the aquarium and the emergence of various kinds of infections.

Aeration of the soil helps the algae to strengthen and develop their root system, but when the soil is oversaturated with oxygen, leaf growth slows down. In addition, in the soil there are no nutrients for algae, they go along with the water. Therefore, this design solution is not recommended for use in an aquarium where a lot of greenery grows.

Even when using a bottom filter, dirt particles still remain on the ground surface. They do not pass through it due to its large size. Therefore, as mentioned above, you have to wash the pebbles. But you can avoid unnecessary mess with changing water and washing the soil.

For this you need to put an additional filter element that will have time to drive through all the water. Or you can buy a device - a siphon, which removes large particles of dirt from the surface of the soil (this procedure is preferably carried out weekly).

Another drawback of the system is that the holes in the tubes quickly become clogged with debris. To clean them, you need to completely pour water from the aquarium and disassemble the entire structure. For a small container (up to 50 liters) this will not cause a particular problem, but for a large aquarium it is very difficult and hard work.

How to make a bottom filter yourself?

There are several ways to build the structure itself. The most optimal of them is the method of using ordinary plumbing pipes.

Measure the length and width of the aquarium. Based on these parameters, it is calculated how many meters will be required for the manufacture of this system. It is better to take a plastic pipe of small diameter (up to 3 cm).

So, for the water intake system will need

  • 3 main pipes (their length corresponds to the length of the aquarium itself),
  • 4 connecting corners,
  • 2 tees
  • 4 small segments (they will interconnect the main tubes),
  • You will also need a plastic separator and a small funnel (a filter will be installed in it).

You can take Plexiglas as a grid, cut the required size and make holes with a drill (it is better to do this with a soldering iron, because it can burst during the drilling process).

The holes should be about 1 cm in diameter and located as often as possible towards each other. Also in Plexiglas, you need to cut a circular hole for the main pipe into which the pump will be inserted. The latter can be purchased at the pet store.

After assembling the pipes into the desired structure, holes should be made in them. The pump, which will pump water, is installed on the main pipe. Accordingly, the closer the holes are to it, the stronger the thrust will be. So that the water is pumped out evenly from all sides, it is best to drill a little more holes on the opposite side of the pump.

So, the pipes are soldered together, the plexiglass and the main pipe with a pump are installed on top. When the whole structure is assembled, after a couple of hours it can be installed in the aquarium. After its installation, the ground is poured from above and water is poured. The system is then turned on and tested for several hours. And finally, you can please the result of the inhabitants of the aquarium.

Is there an alternative to the bottom filter?

Many aquarists claim that bottom filters can already be left in the past. Of course, they quite effectively clean the aquarium from contamination, but to maintain cleanliness, additional methods of care are required. There are alternative devices: external and internal filters.

Each model is designed for a specific volume of the aquarium. Also filters can include the device for aeration of air - the compressor. Such devices are able to pass through themselves the entire volume of the aquarium in just 10-15 minutes.

The advantage of such filters is quick installation and easy maintenance. To make cleaning, it is enough to disassemble it and wash all the structural elements under the faucet.

Conclusion

The bottom filter is an effective way to filter water, which allows it to be cleaned naturally (passing through the soil). This type of construction has both advantages and disadvantages, which is why many aquarists do not dare to acquire it. But why spend money if you can build yourself a bottom filter from inexpensive materials?

This type of filtration was known at the end of the last century, but it is still used today. Difficulties in installation and maintenance make fans switch to more modern methods of water purification using external and internal filters (the latter are attached to the inner wall of the aquarium).

Can you keep an aquarium without a filter?

Can you keep guppies in a small aquarium without a filter, compressor and heater?

Catena

It is possible, but in this case, you must have aquarium plants !! ! and light !! ! (and if there is light, the water from the bulb also heats up, as the heater becomes useless, I have a heater, and what's the point, I haven't even turned it on for more than a year, the water heats up well from lamps), otherwise they will die . And how small is the aquarium? It would be better, of course, that the filter was (which also drives the air), then the compressor is not needed.
As for the water change, so do not listen to anyone who would advise to change the water. Guppies love hard water, so they will feel better, if water is not replaced, but only topped up with something that evaporates, but since there is no filter, you need to siphon the soil at least once every 2-3 weeks. In this case, once the aquarium is small, the water that you pick up from the aquarium with dirt must be drained, for example, through several layers of gauze, and back out into the aquarium, otherwise the fish will hurt.

ELENA ORLOVA

My friend, of course, has all this, but also living algae, imagine how often you will have to change the water, if it is without a drainage (filter) and how is the temperature maintained, the boiler at a time?
