How do goldfish breathe, what to do if a goldfish doesn t open its mouth to breathe?

Summary. One should be that the fish are very comfortable, and the dissolved oxygen in the water is very high, and the water is not allowed to be changed; There is also a bad thing that the fish has enteritis, so you should hurry up.

When the oxygen content in the water is low and the ambient light is dark, the fish tend to sink to the bottom! Take a closer look and make your choice! As long as there are no obvious wounds or diseases on the fish, it is good to swim healthily after a while!

I put the fish in the tap water that I just connected, and at first he opened his mouth to breathe, and then he didn't open his mouth at all.

It may be that the oxygen content of the water is too low.

So what should I do?

First, it's best to control the temperature of the fish tank reasonably. If an aquarium fish prefers water of 26 to 30 degrees Celsius, we would rather choose 26 degrees than 30 degrees, because the lower the water temperature, the greater the amount of dissolved oxygen.

Second, it's best to plant some aquatic plants or water plants in the fish tank. The more plants there are, the higher the dissolved oxygen in the water, and at the same time, the plants can absorb nitrates from the water, so that we can reduce the frequency of water changes in the fish tank.

Can it be solved by raising it with warm water?

No. The water temperature should be low, just room temperature water.

Okay, thanks, I'll give it a try.

Turn on the aeration pump and agitate the water layer. In fact, the efficiency of the aeration pump to provide dissolved oxygen to the water body may not be higher than that of aquatic plants, but in those aquariums without aquatic weeds, the aeration pump can only be used to compensate for the gap in dissolved oxygen. In fact, the aeration pump has an additional benefit, that is, stirring the water layer to fully mix the upper, middle and lower water, so that the dissolved oxygen in all positions in the fish tank is as consistent as possible.

Can I raise fish at room temperature with hot water mixed with cold water in the bath?

Just the temperature of the tap water is fine.

It's not so much trouble.

Can I <> that too?

<> can also be, that is, the temperature of the cold water.

Goldfish is a small ornamental fish that many people will raise, which is easy to feed and looks good, so it is the first choice for many people to raise fish. When we raise fish, we should pay attention to changing the water regularly with new water, or use some tools to help dissolve more oxygen in the water. If we find a goldfish floating on the surface of the water to breathe, it is likely that there is a lack of oxygen in the water.

In this case, you should be careful, it is likely because of the lack of oxygen in the water, if you have not changed the water for a long time, you must change the water in time. Usually, in the absence of oxygen, the goldfish will float their heads, that is, float to the surface of the water to gasp, at this time, it is necessary to take remedial measures quickly, such as changing the water and using a filter, otherwise the goldfish will easily die. Because the water used to raise fish at home is generally free of plankton and other plants, there is usually a lack of oxygen.

So it is necessary to observe the performance of the goldfish in the aquarium at all times.

1.When the oxygen level in the tank is insufficient, the goldfish will float their heads, swim to the surface, and then stick their mouths out of the water as if desperately trying to breathe air. If there are a lot of fish in the water, but the space of the whole tank is small, it will easily cause hypoxia in the water environment, causing the goldfish to foam.

In addition, there is too much food residue and the accumulation of fish excrement, which leads to the deterioration of the water environment. If the water is not purified well for a long time, the oxygen in the water will gradually decrease. When oxygen is insufficient, goldfish will surface and spit bubbles.

2.When there is a serious change in the water quality environment (such as water pollution, etc.), the pH value will change. At this time, the goldfish will also swim to the surface and remain in a state of spitting out bubbles.

3.Goldfish may also spit foam on the surface of the water when the water temperature changes. Goldfish are suitable for living at a temperature of about 20-28. Once the water temperature changes and the goldfish is unable to adapt to the situation, other abnormal problems are prone to occur.

If the goldfish is hypoxic, it usually floats on the surface of the water and its vitality is not very vigorous. But if the goldfish is hungry, it is not necessarily on the water, and it is also very energetic. In the daily breeding process, as long as there are not many fish, often pay attention to water change, there is rarely a lack of oxygen.

To be on the safe side, you can prepare an oxygen pump that allows the air head to enter the fish tank to increase the total dissolved oxygen.

Goldfish come to the surface to breathe, and the exogenous source is oxygen in the water. This is also called "floating head" in the industry, and "floating head" is a manifestation of many fish, which refers to the phenomenon that the head of fish and other animals rises to the surface when the dissolved oxygen in the water body falls to the fish or aquatic animals can not breathe normally.

The dissolved oxygen required by general goldfish is 5 mg per liter, and individual enriched oxygen fish requires 7 mg per liter. Normally, fish with less than 1 milligram of dissolved oxygen per liter in the water will float their heads, less than milligrams per liter will suffocate to death, and highly nitrox fish will die before 05 milligrams. If the dissolved oxygen is less than 5 mg for a long time, even if the fish does not die, it will grow slowly and become lighter in color.

This forces the fish to come to the surface to breathe.

1. The water in the fish tank is shallow, the water is shallow and the dissolved oxygen is uniform, and the fish can have more oxygen even at the bottom of the water. If the water is deep, there will be a large difference in the amount of dissolved oxygen above and below the water, with more in the upper layer and less in the lower layer.

2. The mouth of the fish tank should be as large as possible. The large mouth of the tank, the contact surface between the water and the air is large, and the oxygen dissolved in the water is more, which is conducive to the goldfish to breathe more oxygen and reduce the floating head.

3. Fish farming in small tanks should pay attention to controlling feeding, and it is advisable to eat once a day and within 5 to 10 minutes. Feed less on rainy days and don't feed at night. Fish need to consume more oxygen to digest food, and the low air pressure in rainy days and evenings will reduce the oxygen dissolved in the water, so feeding the fish may lead to severe lack of oxygen in the water and the fish will die.

Most of the dead fish occur at night, and severe lack of oxygen in the water is one of the main causes.

Fourth, the bait must be clean. Feeding unclean bait can easily lead to deterioration of water quality, and the deterioration of water will increase oxygen consumption and fish diseases.

Fifth, keep the water clean. Goldfish eat a lot of food, consume a lot of oxygen and excrete a lot of waste, which pollutes the water and exacerbates the lack of oxygen in the water. Therefore, it is necessary to renew a part of the water every day, and it is best to change the water at night to survive the low oxygen period at night.

6. Do not bring greases into the water. The oil will float on the surface of the water to isolate the air, so that the oxygen in the water cannot be replenished, which will cause the goldfish to die of lack of oxygen. Eating meat or applying hand cream to your hands can bring grease into the water and should be carefully avoided.

In order to solve the problem of breathing in rapid movement, tuna put the gills on the go.

Open. As long as you swim quickly, the water passes through the gills of the fish to get oxygen. This type of breathing is tuna's unique percussive breathing.

The faster the tuna swims, the more water hits its gills and enters its body, giving the tuna the oxygen it needs to move at high speeds.

The gill muscles of tuna have degenerated, and they always have an open mouth and swim constantly, getting oxygen from the fresh water flowing through their gills.

If the tuna stops swimming, it will suffocate and die due to lack of oxygen. This type of breathing, in which the mouth opens so that the water flows directly through the gills to breathe oxygen, is called impact breathing, and tuna belongs to this category.

So the tuna will swim and sleep at the same time.

Goldfish can breathe in the water and absorb oxygen dissolved in the water, but they cannot directly absorb oxygen from the air because the respiratory organs of fish are gills.

1. The gills of fish are born on the head, which is generally covered by the gill cover. The gill lift is composed of gill filaments closely arranged like a comb, and the gill filaments are flanked by protruding gill patches that are densely covered with microvessels.

2. When the water passes through the gill filaments, the microvessels on the gill patches absorb the dissolved oxygen in the water, and at the same time discharge the waste gas and carbon dioxide in the body. As a result, water flows through the gill slits and the fish can breathe continuously.
