What aquarium fish live without oxygen and air



11.10.2013 added

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.

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.

To ensure a comfortable life for the fish without additional aeration, it is necessary to choose the right plants and settle the optimal number of inhabitants.

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.

If bacteria and fungi are O2 deficient, then they begin to more slowly cope with the goal. Return balance in the ecosystem, you can only increase the supply of oxygen.

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!

It is necessary to take into account and do not turn off the aerator at night.

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: Fish has an aggressive nature.

Description:

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.

Macropods are long-lived and can live up to 8 years.

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 must be correct: balanced, diverse. This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses.

Article “How and how much to feed aquarium fish” talks in detail about this, it outlines the basic principles of the diet and feeding regime of fish.

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.

Aquarium from a can – keeping aquarium fish in a can

Aquarium from the can

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. I think this article will help you navigate the process and the nuances of creating a mini-canned aquarium.

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.

2. Soil: you can buy a beautiful (colored) small packaging in the pet store, it is not expensive. As the ground, you can also use small pebbles, other river or sea pebbles.

Such a soil should be washed and boiled before being placed in a jar.

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?


Cock, Betta or Boytsovskaya fish

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.


Guppy

Guppies are lively and not capricious fish. They have 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: Aquarium pot – this 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!

Here, the sample – costs 10 euros

Rectangular aquarium TM “Nature” 40x25x34 34lIt is a model of unity of low price and decent quality product. This is a great choice for people who love to sculpt their own dream!
Volume: 34 l, Dimensions (LxWxH): 40x25x34 cm Aquarium shape: rectangular.

Here are the options for decorating mini aquariums.



The life expectancy of an angelfish in an aquarium can be 15-25 years, if you follow a number of requirements. First, be sure to launch these fish into a spacious tank of at least 100 liters per pair (female and male). Secondly, install the compressor and the aerator, the fish saturated with oxygen will only be delighted.

The compressor must be turned on for 20-30 minutes twice a day.

As for the general cleaning in the aquarium, it does not need to be carried out too often. If you remove the remnants of food and rotted plants in time, the water can be changed less often, some people manage to keep the water in crystal purity for more than six months.

Otherwise, water replacement should occur at least 3 times a month. Be sure to clean the soil, wash the walls of the tank and the filter from the accumulated dirt, green algae.

Watch the water temperature – the new water should correspond to all the parameters of the “old” one.


Do not forget that the angelfish will live more years if the feed in the aquarium is not worse than they are fed in the wild. In the wild, they are omnivorous: they feed on insect larvae and insects, zooplankton, and plants. Therefore, they can be fed all appropriately feed: artificial for cichlids, dry, frozen and live.

You can not give bloodworms and tubers, because they do not live in weakly acidic water. You can see how the fish form brownish blisters at the anus – these are the negative effects of feeding the bloodworm and the strawman.

What decorative angelfish eat: micro-worm, artemia, earthworms, snails, koretra, daphnia, cyclop, lettuce and spinach. It is not recommended to give meat to warm-blooded animals that are saturated with fats. Feed pelleted with spirulina can be additional feeding.

You need to feed such portions so that the fish ate the food in 2-5 minutes. Overfeeding is also harmful and shortens the life of fish, food debris can oxidize water, spoiling its quality.
