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 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 head.

Is it difficult to keep aquarium fish? Such a question is often asked by novice aquarist lovers. They are afraid that they will not cope with the care, feeding, settlement of pets.

Like any living creature, aquarium fish requires attention and care, but how to create comfortable living conditions for it, if you don’t know enough about the aquarium business? In this case, your pets can become unpretentious aquarium fish. They are easy to maintain, unpretentious fish are considered very hardy, tenacious, get used to the person.

If you are very busy, and you do not have enough free time to care for animals, then the most unpretentious aquarium fish will significantly reduce the time for employment of the aquarium.

What unpretentious aquarium fish successful for a beginner who does not have much experience in maintaining the aquarium? When there is a desire to create good conditions for their pets, you can choose small and beautiful fish with a peaceful disposition, who can live in not very capacious tanks.

Guppies are one of the most popular decorative pets in an aquarium. Outwardly very bright, cute, have a beautiful tail. You can keep in small tanks of 40 liters, are able to transfer changes in water parameters.

Some guppies can withstand the lack of filtration, aeration, plants, although such a settlement is not strongly recommended. Guppies are prolific, viviparous fishes. Perfectly get on with small and peaceful fishes.

For this reason, they have been popular in our country for many years. In addition, the variety of color patterns is striking – you can choose a school of fish of different colors, whose offspring will be even more colorful.

Watch a video about the content, care and reproduction of guppies.

Swordtails – they are easily recognizable by the tail fin, which in males ends with a “sword” in the lower base of the tail. There are also many types of swordtails: color variations, sizes, behaviors prove that these are very interesting pets.

The main advantage – they are hardy, livable with many ornamental fish, do not spoil the aquarium decorations. It is advisable to settle in a 20-50 liter tank, where there are many shelters and dense vegetation. Swordtails can stand up for themselves – they can be accommodated with active fish that love to disturb their neighbors.

Swordsmen are survivable because the female of this species suddenly becomes a male, which saves her in a critical situation.

Somiki corridors – unpretentious inhabitants of home aquariums. As you know, catfish are generally undemanding in maintenance, they are even ready to help in cleaning the tank – they eat up the remnants of undernourished food, eat algae. Do not bother their neighbors, because they float in the lower layers of water.

Corridors can be called “two-breathing” fish, except for gill breathing, gather air in the intestine, which helps them survive in the absence of aeration. The nature of the fish is calm, peaceful, they can be settled even with larger fish.

It is better to have a flock. The minus of these pets – some individuals carry with them parasites, if kept before the purchase is wrong.

Their sizes are small – from 3 to 10 cm, so you can settle in small aquariums.

Mollies are viviparous fishes of the Pecilia family. Rather hardy, maintain small changes of parameters of water. However, their bodies do not withstand bad biological stress – dirty water, low water temperature, fresh water.

Prefer salted ponds and bright lighting. Some mollies may conflict with the swordtails, barbs.

The character is peaceful but unpredictable.

Tetras are another popular fish of the Kharacin family. Unlike corridors and guppies, they will not be able to survive under stringent conditions of maintenance – they need a lot of dissolved oxygen in pure water.

Schooling fish, you can settle in a common tank with a capacity of 35 liters, a flock of 5-6 individuals.

Gourami – easy-to-keep fish, suitable for beginners. Need a portion of atmospheric oxygen, so you have to follow the aeration.

Gourami are able to stand up for themselves, they eat live, frozen and vegetable food. Sometimes gourami can show aggression towards the fish of their own species.

See how to contain pearl gourami.

Barbus – easy to care for and keep pets, but with what character! Considering the fact that they are schooling fish, they can reach other neighbors, especially bright ones with lush fins.

These are pirates of domestic aquariums, they can disturb even large cichlids, they are not suitable for a small common aquarium. Advantages of barbs – endurance, livable, beautiful appearance.

Deciding what kind of fish to start first in your tank can be sudden, and can be thought out. Unfortunately, novice aquarists are often guided by the very first impulse, completely without understanding the fish.

And then, instead of joy and pleasure, they get a headache and problems. You need to choose the fish wisely, because their life and your comfort depend on your choice.

Before you go to the store or to the market, study all the available information about the fish that you liked.

What kind of fish is not worth buying for beginners, we have considered here. And the top 10 unusual fish here.

And in order to make it easier for you to navigate, we have compiled a list of the best aquarium fish for beginners and briefly described them. All of them are distinguished by unpretentiousness, tolerance to conditions in an aquarium, peaceful nature, livableness and modest size.

We hope that it will help make your choice easier!
