Fish That Live Without Oxygen In The Aquarium

What aquarium fish can live without oxygen

At first, I would like to immediately make a reservation. All life on earth can not live without oxygen, or rather without air. Therefore aquarium

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).

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.

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, the owners of which are referred to as the labyrinth family.

Fish That Live Without Oxygen In The Aquarium

A labyrinth is a specialized respiratory organ that allows you to absorb oxygen directly from the air. Labyrinth fish take the air "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.

Fish that can survive without oxygen in the aquarium

It’s no secret that oxygen is present in the aquarium in a dissolved form. Fish constantly consume O2 and emit carbon dioxide. When an aquarium is artificially highlighted, the fauna highlights it during photosynthesis.

The most common problem is considered an imbalance in the number of green spaces and fauna. In the event that plants are not able to cope with providing all residents with oxygen, aquarists are forced to resort to using special devices for aeration.

The presence of oxygen in water is the main criterion for the life of almost all aquatic organisms. Aquarium fish are demanding on the saturation of water O2. This indicator can be called one of the main in determining the chemical composition.

Oxygen is essential for both fish and other creatures and plants. Each type of underwater inhabitants has its own requirements for aqua saturation. Some of them easily carry oxygen-poor water, others are sensitive to minor fluctuations.

Few people know that an excess of oxygen can also have a detrimental effect on fish. How to determine the optimal indicator? If there is not enough oxygen, the growth of the fish slows down. This is primarily due to the wrong process of assimilation of food.

Creating an ideal ecosystem, consider that in addition to fish, oxygen is consumed by other organisms from the aquarium: ciliates, intestinal cavities, mollusks, crustaceans, and even plants in the dark period. It is not difficult to guess that the more inhabitants, the more oxygen they consume.

It happens that the wrong organization leads to the death of the fish. In the process of oxygen deficiency, fish begin to choke due to accumulated carbon dioxide.

Causes of oxygen deficiency:

  • High density of inhabitants;
  • High salinity and temperature of aqua;
  • The consequences of improper treatment;
  • Alkalinity jump.

As a result of the increase in the thermometer, the processes occurring in the body of the fish are intensified. This leads to an increase in oxygen consumption. If the figures have crossed the mark of 28 degrees, then the fish begin to consume more O2 and emit a large amount of carbon dioxide, which leads to starvation and, if it is not urgent to react, then to the death of pets.

Lack of oxygen in a polluted aquarium is also dangerous. Various oxidation processes will occur in it, which will have a negative effect. It is very important to monitor compliance with the number of tailings and water quality. Try to provide pets with high-quality filtration.

It is worth saying about bacteria, which are an integral part of the underwater world. The increase in the number of inhabitants leads to a large amount of excrement, which leads to an increase in the ammonia content of the water.

All wastes that are subject to mineralization are carefully treated with bacteria. Thus, the more organic elements, the more bacteria that also need oxygen. As a result, the circle closes.

But there is another side to the coin. Thus, high oxygen saturation leads to an increase in pH. This situation is not welcome in the aquarium, because the difference in the water being replaced will be too global.

Pay special attention to the flora of your aquarium. Because plants are an amazing and very important part of creating the right microsphere. All plants produce oxygen during the day, but consume it at night!

The edges of the round aquarium

Experienced aquarists prefer rectangular aquariums, while skeptics are considered to be round tanks. You can hear that the round aquarium is inconvenient to maintain, it is dangerous to the health of the fish, and caring for it does not justify itself.

In fact, the content of the flask has several disadvantages. But the observance of certain rules and knowledge of which fish are suitable, will allow for many years to ensure a comfortable life for the inhabitants. And, of course, it will be an excellent interior decoration.

disadvantages

For a start, it is still worth to identify the main disadvantages of a round aquarium.

  • Small volume The standard sizes of round containers are designed for 10, 20 or 30 liters. A small round aquarium may be beyond the strength of an inexperienced aquarist. A round container must also be equipped with a filter and other devices.
  • The size. The volume will not allow to keep any kind of fish. With plants to roam, too, will not work.
  • The number of inhabitants. A space of 10, 20 or 30 liters will allow you to contain two or three fish. Plus, these fish should be small in size and have a number of qualities that will be discussed below.
  • Distortion. The glass aquarium has curved walls, they will reflect the light and create a shadow, causing the illusion of movement. Fish, prone to stress, will suffer.
  • Inconvenience. Caring for such an aquarium is more difficult. It is necessary to carefully monitor the filter – it becomes dirty more quickly. Its maintenance is troublesome, and frequent water changes and wall cleaning will be an extra stress for fish.
  • Oxygen. Due to the shape of the oxygen layer in the flask is small. There will be less dissolved oxygen in the water, so the fish demanding such a parameter should not be chosen.

Equipment

Required equipment includes:

If you are interested in a round aquarium, it is worth considering its drawbacks carefully, but not to be afraid of them. First, decide on the volume. As mentioned above, the average volume of round aquariums is 10 liters, but you can buy containers for 20 or 30 liters.

You will need special equipment to create a cozy environment. This compressor, bottom filter and heater. It is also necessary to provide the glass aquarium with illumination, but it will be difficult to install it yourself. In order not to complicate your life, it is better to purchase a container with a built-in lamp.

In addition to the equipment you will need a cover for a round aquarium. She has several tasks at once:

  • prevents fish from jumping out of the tank;
  • serves as protection from curious cats that may wish to eat fish;
  • A lighting fixture is attached to the cover.

The popularity of round aquariums and goldfish is due to two main factors – goldfish are among the most hardy and unpretentious aquatic inhabitants, and round aquariums are in harmony with any interior and are easy to clean.

Macropod fish: content, compatibility, photo-video review

Order, family: labyrinth.

Comfortable water temperature: 20-25 ° C.

Ph: 6.0-7.5.

Aggressiveness: aggressive 40%.

Macropod compatibility: with moving fish of the same size (gourami, crescent, zebrafish). Not recommended to settle with the "Golden Fish".

Personal experience and useful tips: The fish is aggressive.

The birthplace of the fish is the reservoirs of Korea, China, South Vietnam, Taiwan.

The body is elongated, flattened laterally, flexible. Dorsal and anal fins long. In the male, in contrast to the female, the ends of the dorsal and anal fin are more elongated and pointed. Fish size up to 10 cm.

The fish belong to the labyrinth order and, like all members of this genus, they breathe atmospheric air through the gill labyrinth.

Moving fish of similar size can be neighbors. Strictly contraindicated neighborhood with the family of "Goldfish". Fish tend to jump out of the water – the aquarium should be closed.

Comfortable parameters of water for the content: dH up to 25 °, pH 6.0-7.5, t 20-25 ° C. Aeration is not necessary for fish. Filtering can be put.

Feeding any aquarium fish should be correct: balanced, varied. This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses.

In this article, we note the most important thing – feeding fish should not be monotonous; both dry and live food should be included in the diet. In addition, you need to take into account the gastronomic preferences of a particular fish and, depending on this, include in its diet ration either with the highest protein content or vice versa with vegetable ingredients.

Popular and popular feed for fish, of course, are dry food. For example, hourly and everywhere can be found on the aquarium shelves of food company "Tetra" – the leader of the Russian market, in fact, the range of feeds of this company is striking.

In the "gastronomic arsenal" of Tetra are included as individual feeds for a certain type of fish: for goldfish, for cichlids, for loricarids, guppies, labyrinths, arovan, discus, etc. Also, Tetra has developed specialized foods, for example, for enhancing color, fortified or for feeding fry. Detailed information on all Tetra feeds, you can find on the official website of the company – here.

It should be noted that when buying any dry food, you should pay attention to the date of its production and shelf life, try not to buy food by weight, and also keep the food in a closed state – this will help avoid the development of pathogenic flora in it.

conditions of fish in the bank

And who said that the first aquarium should be immediately "fildepersovy". I am sure that almost all the gurus of akriumistiki started with a small aquarium. My first aquarium was 35 liters and this did not prevent me from developing in this direction, on the contrary allowed me to taste the aquarium world and get the first experience.

Therefore, if you want to try doing aquarium fish or just don’t want to pay money for expensive aquarium and equipment, I suggest you consider creating an aquarium from a simple can.

Section 1: What you need to create an aquarium from a can.

1. Can / bottle: you can use a 3 liter bottle, but I draw your attention that the larger the can, the better. I know that there are banks of 5 and 10 liters. In addition, glass decorative flowerpots are being sold now – you can adapt them.

3. Compressor: necessary for supplying oxygen to the aquarium, it is not expensive at about $ 6. If the aquarium can is large (from 10 liters), you can purchase a filter with aeration – this will relieve you from the routine care of the first aquarium.

4. Decor: should not be large, I think one seashell will be enough.

5. Fish and plants.

Section 2: The process of creating an aquarium from a can.

1. My jar of soda, pour boiling water, wash everything thoroughly.

2. Fall asleep ground.

3. Install the decor.

4. Fill the water.

5. Planting plants.

6. We adjust biological balance.

7. Run the fish.

Section 3: The nuances of creating an aquarium from a can, what to look for?

First, the bigger the pot the better. Try to get a can of as large a volume as possible. The larger the bank, the better the fish, the easier it will be for you to care for it.

Secondly, in no case use a plastic jar or bottle as an aquarium. Plastic poison the fish, but also it is less transparent than glass.

Third, since the filter does not fit into a small jar, you should perform its function weekly – siphon the bottom, wipe the jar with a clean sponge from the inside, and replace it with a little fresh water.

Fourth, fill and replace only the separated water.

Fifth, please note that the aquarium pot can not be put on the window sill or other sunny place. From this, the aquarium will bloom, and the fish will die.

Sixth, try to maintain the temperature required for the fish. Buy a thermometer and see that the temperature is not critical.

Section 4: Fish in the bank, which fish can you keep?

The unconditional recommendation would be a fish – Cockerel or Betta. This very beautiful unpretentious fish that does not need aeration (compressor), as it swallows air from the surface of the water with the help of a special organ – gill labyrinth.

Guppies are lively and not capricious fish. Possess beautiful tails. I happened to see a mini aquarium with gopashkami without the slightest care (aeration, filtration, etc.) – and they lived. If you create comfortable conditions for guppies, they will also bring you posterity, because they are viviparous and breed like rabbits.

Here is another series of fish that can live in aquabank: swordtails, neons, tetra, catfish speckled, mollies, danios pink.

As an epilogue: an aquarium bank is certainly an option for the first steps in the aquarium kingdom. But it is also indisputable that the small fish in the bank will closely and adjust the biological balance in such a vessel is also difficult.

The cost of aquarium bottle will cost you a penny, in fact for nothing. But still I suggest you to think about an aquarium for $ 15. This aquarium will greatly facilitate the care of pets and will only please you!
