What fish can live without oxygen and filter :: aquarium fish breathing atmospheric air :: Aquarium fish
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 store. Business is not going. What to do? “- 2 answers
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 don’t 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 dubbed “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 cockerels. 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 head.
Aquarium Aquarium: Methods and Methods of Enriching Aquarium Water with Oxygen
Everyone knows that equipment for aeration of aquarium water is paramount and vital.
However, many beginners and even already experienced aquarists do not know how it works, they do not fully understand why it is needed and what happens in an aquarium with a lack or excess of oxygen.
In this article, I would like to try in a simple narrative manner to lift the veil of aquarium aeration secrets, to bring excerpts from the already written material of Runet, and also to tell about some of the “secrets” of O2 supply to the aquarium.
I think I should start with a short story about mechanical aeration, by which I mean the process of mixing air with aquarium water using aquarium equipment (pumps and compressors).
The principles of operation of such equipment are well known and understood by everyone, so I will not focus on them. It is more interesting to tell about two misconceptions of newcomers of the aquarium craft, connected with the aeration of the aquarium water by mechanical means:
1. Usually everyone thinks that the enrichment of water with air occurs through bubbles, which the compressor will drive into the water. However, it is not! Mixing air with water occurs on the surface of the water.
The aerator creates vortices and vibrations from bubbles on the water surface, as a result of which mixing occurs. We can say that the saturation of aquarium water with air (oxygen) is not due to the bulbushes, as such, but from their intensity and water flow, which improves the absorption of oxygen from atmospheric air.
2. The second important nuance of mechanical aeration is its continuous operation. A big mistake for beginners is to turn off aeration for the night, so that it does not rustle.
Such an action can lead to fatal consequences, because overnight asphyxiation will “earn” not only fish, but also all hydrobionts, up to nitrifying bacteria, which leads to a disturbance of biobalance and, as a result, a “dead bog” is obtained from the aquarium, which is infested with disease-causing bacteria and live algae!
With that said, it should be noted that you should not save money when choosing and buying equipment for aeration of the aquarium, it must be of good quality and sufficient power. It is desirable that it had various nozzles and created a good “purge”.
A huge role in the “aeration of the aquarium” is played by live aquarium plants. Aquarium plants are perhaps the only natural source of “pure” oxygen – O2, which is released during photosynthesis.
The presence of abundant vegetation in an aquarium will have a favorable effect on its climate and, in particular, on the concentration of oxygen in the water. However, the plants are not a stable and unconditional supplier of oxygen to the aquarium.
It is worth saying that the process of photosynthesis, in which plants emit oxygen is possible only if there is sufficient illumination and the necessary amount of CO2 (carbon dioxide). As soon as the light in the aquarium turns off, the process of photosynthesis stops and the opposite happens – the plants begin to consume oxygen.
From the above, we can draw two conclusions:
– aquarium plants are not replaceable helpers “oxygen supply in the aquarium.” I generally keep quiet about their use in setting up the biobalance and their participation in the fight against NO2NO3.
– Alas, aquarium plants are not a panacea. Many people are mistaken in thinking that plants need only carbon dioxide, no!
They also “breathe” and oxygen is vital for them at night.
Well, now, before disclosing “aquarium-oxygen secrets,” let’s determine
Aeration, enrichment of aquarium with oxygen interesting video
The distinguishing feature of the labyrinth family of fishes is the structure of their respiratory system. Adapting to living in oxygen-poor water, the fish of this family developed a nadzhaberny body – the so-called labyrinth.
The system of channels in the cavity of the gill arch is called a labyrinth organ.
Fish from this family gasp air through their mouths, which enter the nadzhaberny body, where blood is enriched with oxygen in the air. Lingering in the labyrinth, the air allows these fishes to remain without water for some time or live in water that is poor in oxygen.
Since the air such fish grab from the surface, then in a tightly closed container, they very quickly die. This specificity must be considered when transporting them.
When these fish are transported in closed cans, labyrinth aquarium fish without oxygen die very quickly.
Most of the fish in this family have beautiful coloring and original body shape. Many fish have an original feature – they touch various objects with the help of modified threadlike fins. The natural habitat of most labyrinth fishes is standing or slowly flowing water bodies, rice fields or irrigation ditches, densely overgrown ponds and shallow rivers.
The water in these bodies of water is usually very dirty, with a low content of oxygen, which served as the formation of a labyrinth organ.
Most labyrinth fish do not pose any problems in their content. The volume of their place of residence is not particularly important. Like fish that do not need oxygen, they suggest some conditions of their maintenance:
The temperature of the aquarium water should be 24-27 ° C.
The soil used should preferably be of a dark color – this enhances the color of the labyrinth fish, which emphasizes their beauty.
For females of this family, dense vegetation is needed, so that there is where to hide from aggressive males.
Labyrinth fish are not particularly picky to feed and willingly eat both live food and dry or frozen.
Keeping them together with representatives of another or one’s own fish species is often problematic. Many adults (often males) show aggression towards the fish of their own species.
Especially often this happens when the volume of the aquarium is small.
In order for peace and tranquility in an aquarium, the water must be “old”; water replacement provokes the breeding instinct and causes aggression.
