What ornamental fish can live without oxygen, and what fish can be raised without oxygen

Guppies. Guppies are a common small tropical fish that also requires very little oxygen. Mary Fish.

Mary fish are resistant to low dissolved oxygen environments. Bettas: Betta fish have an accessory respiratory organ that allows them to breathe oxygen at the surface of the water.

Goldfish: Goldfish have a long history of cultivation in China, and the demand for oxygen is not high. Lampfish:

The lampfish refers to the fish of the lamp family, which does not need oxygen.

Guppies are a common small tropical fish, and due to their relatively small size, they require very little oxygen and do not need oxygen to survive. However, it should be noted that if the number of breeding is relatively large and the density is relatively large, there will still be a danger of insufficient oxygen, so don't raise too much.

Mary fish are also small fish, but they are inherently resistant to low dissolved oxygen environments, so they do not need oxygen to survive. This fish also has a more fertile habitat in the wild, and can live in both freshwater and sea, usually on algae.

and organic debris feeding, stain resistance is also relatively strong.

Betta fish are generally divided into Chinese betta fish.

And the Thai betta fish, both betta fish survive in places with low oxygen content, not only them, as long as they are fish of the same family as it, they have an auxiliary respiratory organ that allows them to breathe oxygen on the surface of the water, so they are very resistant to low oxygen, and they don't have to worry about being suffocated.

Goldfish have a long history of cultivation in our country, and they can be cultivated in ancient times without oxygenation equipment, so there is no problem without oxygen. The varieties of this fish are divided into four categories, which are grass species and literature species.

Dragon species and egg species, among which grass species are easier to raise, and other kinds still have requirements for oxygen.

The lampfish refers to the fish of the lamp family, which is not an accurate biological taxonomy.

Rather, they are small, colorful aquarium fish.

can all be called light fish. The common variety is the Pauline lamp.

Traffic lights, red-nosed scissors, etc., because they are smaller, they can feed without oxygen.

If we don't get oxygen, we can raise goldfish. Goldfish are not only very beautiful in appearance, but also very easy to raise, and do not need oxygen, which is a very good choice. At the same time, the horse-vested fish does not need oxygen, and the appearance of the horse-vested fish is small and exquisite, delicate and cute.

1.Goldfish A fish that can live without oxygen, and the first thing that comes to my mind is goldfish. As one of the three most popular ornamental fish in the world, as we all know, goldfish are really very easy to feed, not only do you not have to worry about the water temperature, but you don't have to worry too much about oxygen.

2.Horsetail Fish Horsetail fish are small, delicate and cute, and the most distinctive thing is that they have two long, thin lines of "whiskers" under their heads. They have a black line from their eyes to their tail, and their bodies are covered with white spots, like pearls, which is probably why they are also called pearlfish.

For example, goldfish are fish that can survive without oxygen, and all the fish in my house are just put in the fish tank.

The fish that are not oxygenated or changed the water are guppies, medakas, and moonfish.

1. Guppies.

Guppies are arguably the most famous of the tropical fish. A fish that can burst even if it is thrown into a bucket. Commonly known as the little prince of the bursting cylinder.

It can be seen that his reproductive ability and ability to get started are very strong. Like moonfish, guppies are viviparous. Very reproductive.

4 guppies were raised, and the number increased to more than 60 in just half a year.

2. View the medaka.

The medaka is a popular fish recently, and it can be raised in a container with a very shallow water depth without jumping out of the tank, which is very suitable for raising this kind of fish in the fish tank of landscaping. And he is very leathery, resistant to high temperature and cold, and has raised some medaka on the balcony, without oxygen, without filtration, and is particularly well raised.

3. Moonshine fish.

Moonshine fish can survive even in harsh environments, and it is very worry-free when it comes to reproduction. It is the first recommendation in "Iron Fish". That being said, it is not entirely possible to leave it alone.

The water should also be changed 1 or 2 times a month, or the evaporated water should be replaced. Moonfish is very hungry and can be used for half a month. However, if they are not fed all the time, it will be difficult for them to grow, so it is recommended to feed them every day as much as possible.

They are all tropical fish, and they are relatively small, so they do not require much oxygen and are more resistant to dirty water. There are also fish that are highly adaptable and do not have high requirements for water temperature. So there is no need for oxygen.

Fish in tanks generally do not require oxygen. This tank holds a lot of water, and there are very few fish raised, and they are all slightly smaller fish, and the water surface is in contact with the air, so there is rarely a lack of oxygen. In addition, this kind of cylinder is relatively deep, and the bottom pressure of oxygen injection is high, and there may even be no bubbles.

If you keep some aquatic plants in the tank.

words, through photosynthesis.

It can also produce oxygen.

1. Maintain water quality: The oxygen content in the water is high, which has a certain role in maintaining water quality. It is mainly divided into two aspects, on the one hand, oxygen promotes nitrification bacteria.

growth and reproduction, so as to better convert ammonia nitrogen.

On the other hand, it inhibits anaerobic bacteria.

to prevent the deterioration of the water body.

2. Conducive to breathing: the main purpose of oxygen is to make the fish breathe better, although this animal lives in the water, but also needs to take in the oxygen in the water, in order to maintain the dissolved oxygen in the water, you need to inject oxygen into the water. Of course, a certain amount of oxygen can also be added by means of water change and filtration.

3. Accelerate growth: The higher the oxygen content in the water, the more energetic the fish will be, which will also promote their growth and accelerate digestion. Of course, there are many conditions required for growth, in addition to sufficient dissolved oxygen, water temperature and abundance of feed.

Raising tropical fish does not need to be oxygenated all the time, and the fish tank has a great relationship, the fish tank is small and needs oxygen, and the reasonable tank body is generally filtered, and there is no need for oxygen.

And any living thing needs oxygen to survive, without oxygen there is no life, and the survival of tropical fish is also inseparable from oxygen. The oxygen needed for fish survival is obtained by absorbing dissolved oxygen in the water through the microvessels of the gills, and then brought to and by the blood circulation system, and the carbon dioxide excreted is also carried out through the microvessels of the gills.

1. If oxygen is not required: reasonable water environment. The amount of dissolved oxygen in the water directly affects the growth of the fish, so it is necessary to ensure that there is enough dissolved oxygen in the water.

In addition to being obtained by mixing with water and changing water, dissolved oxygen in water can also be produced by photosynthesis of aquatic plants in water. That is to say, if there is a large enough tank and fruit, there is no need for oxygen.

2. Situations that require oxygen: lack of light. Without light aquatic plants, they cannot photosynthesize, absorb carbon dioxide and produce oxygen, and plants cannot sustain themselves.

However, plants also have certain requirements for light, and if the light is too strong or the light time is too long, aquatic plants will grow green moss, which will affect the photosynthesis of aquatic plants.
