What is the reason why goldfish always float to the surface and spit bubbles?

When there is no oxygen in the tank, the goldfish will float their heads, they will swim to the surface of the water, and then poke their mouths out of the water, blinking and blinking, as if desperately breathing oxygen in the air.

There are many reasons for the lack of dissolved oxygen in the water, for example: there are many fish raised in the water, but the space of the whole fish tank is small and the water is small, so it is easy to lead to a lack of oxygen in the water environment, making the goldfish spit bubbles.

There are too many food residues in the water environment, and the excrement of the fish accumulates, resulting in the corruption of the water environment, and the water quality is not better purified for a long time, and the oxygen in the water will gradually decrease, and when the oxygen is insufficient, the goldfish will have bubbles.

Goldfish have a mild temperament, generally live for about 6 years, and there are longer ones, goldfish belong to an omnivorous carnivorous freshwater fish, with well-developed throat teeth, can swallow harder bait.

Goldfish have a strong ability to adapt to water temperature, but can not adapt to the drastic changes in temperature, its suitable water temperature is 18-26, too high or too low will affect the feeding and growth and reproduction of goldfish.

Goldfish prefer weakly alkaline water, and the pH value of the water body is more suitable. At the time of the transition of spring and summer in northern China, when the water temperature begins to rise, goldfish also enter the breeding period, and the water temperature during this period is controlled at about 20, which is more conducive to the spawning and hatching of goldfish.

1. Hypoxia. The lack of oxygen can cause goldfish to float or spit bubbles in the water, and they can also poke their mouths out of the water, as if they were breathing oxygen in the air.

2. Indigestion.

Goldfish will also spit bubbles when they have indigestion, just like people burping, usually because they are overfed or eat indigestible food.

3. The water quality is too poor or the water temperature is too low.

Although goldfish do not have high requirements for water temperature and water quality, too low water temperature or poor water quality will also cause goldfish to float on the surface of the water and spit bubbles.

Precautions for raising goldfish

1. Try not to buy goldfish during the change of seasons.

Goldfish can easily get sick if the temperature difference is too large during the change of seasons, and if new aquarists don't pay much attention to this problem, they will suffer unnecessary losses, and don't buy them in the middle of summer and cold winters.

The temperature in the middle of summer is too high, inexperienced aquarists may cause goldfish to die of lack of oxygen in the process of buying fish, and the goldfish in the cold winter season are basically in a state of hibernation.

2. Goldfish like old water, don't go to a large area to change the water for goldfish.

Among all the ornamental fish, goldfish are the fish that do not like new water the most, and it is better to be stuck in water for at least three days, so that goldfish will better adapt to the water quality.

Your fish is foaming because of a lack of oxygen in the water.

Once there is a lack of oxygen in the water, the fish will float to the surface, the mouth will open and close, and when there is a slag, it will make a "horn, horn" sound, trying to breathe oxygen from the empty oxygen, and then spit out the air inhaled into the mouth, forming a bubble.

The main causes of hypoxia in water are as follows:

1. Less water, more fish are raised, resulting in a lack of oxygen in the water.

2. There are many residual bait or excretes in the water, and the water quality becomes poor, and the aerobic bacteria compete for oxygen with the fish, resulting in a lack of oxygen in the water.

3. After feeding more, the metabolism of the fish is vigorous after being full, and the oxygen consumption increases, resulting in a lack of oxygen in the water. Lead matching.

4. Weather changes, low air pressure, and reduced dissolved oxygen amount, resulting in hypoxia in the water.

5. Oil or detergent is brought into the water, isolating the air from the water, and unable to dissolve oxygen into the water, resulting in a lack of oxygen in the water.

In addition, if the fish are weak or sick, and shortness of breath will also float to the surface and spit bubbles.

1. To raise good fish, you must first learn to buy good fish: healthy fish swim and forage in the middle and lower layers of the water body, with bright colors, natural and leisurely swimming posture, and clear and transparent tail fins. Those who sink to the bottom, float their heads, swim and struggle, have trauma, white hair, white spots, thick tail fins, turbidity, severe bloodshots, and are alone are diseased fish that must not be purchased.

2. Don't rush into the tank after buying the goldfish home, you should first put the plastic bag containing the fish into the fish tank for ten to twenty minutes before opening it, and then let the water in the tank pour into the bag several times, and gradually mix with the original water in the bag, so that the fish can gradually adapt to the water temperature and water quality. If there is a light, the light should be turned off, and the fish are quieter in the dark and are not easily frightened. Fish frightening is one of the important causes of disease.

3. The temperature of the water cannot be changed drastically. Goldfish can survive in a wide range of temperatures, survive below the ice in winter, and live normally on hot days as long as they are not exposed to the scorching sun, but if the temperature changes drastically, it can lead to illness or death. The water temperature of the fishmongers drops to 5 degrees or even lower in winter, and more than 30 degrees in summer, so you should pay attention to the water temperature in the aquarium store and the water temperature in your fish tank when buying fish, and the deviation should not be too large, generally within 4 degrees is allowed.

4Therefore, the new water for changing the goldfish must be stored for a day or two, which is called drying water. On the one hand, the purpose of drying water is to remove some of the chlorine in the water, and the main thing is to bring the temperature of the new water close to the old water.

5. Do not change the water too much at one time, which will lead to water quality discomfort. Water quality includes pH, hardness, residual chlorine, dissolved oxygen, nitrate, sulfide, protein and turbidity. Goldfish have adapted to live in the original water quality, and if the water quality is suddenly changed by changing all the water, the goldfish will not be able to adapt and suffer from water incompatibility.

1.You must be feeding dry bait, and when you feed the fish, the bait floats on the surface of the water, and they are used to looking for food on the surface, so when they see someone coming, they think they are coming to give them food, so they come up.

2.If there is a lack of oxygen, change the water frequently.

3.Spitting bubbles is breathing, if your golden fish swims on the surface of the water, frequently spits bubbles, and stretches your mouth out of the water to breathe, even if you hit the edge of the tank with your hand, you will not be alarmed, and will still float on the surface of the water after sinking, or immediately float on the surface of the water to breathe. This phenomenon is called water.

It is a symptom of hypoxia in goldfish.

Goldfish surface for three reasons:

1. Hypoxia: causing goldfish to float;

2. Water quality: The water for raising goldfish is clean, refreshing and pollution-free, and the natural water can be directly used to raise fish. The water must go through the process of raising water for 2 to 3 days, and pay attention to keeping the water quality clean during the cultivation process;

3. Water temperature: The most suitable temperature for goldfish is 20 degrees to 28 degrees, pay attention to heatstroke prevention and cooling in summer, and pay attention to heat preservation in winter. Goldfish are particularly sensitive to sudden changes in feed water temperature, and the smaller the ability to tolerate water temperature differences, the weaker they can tolerate water temperature differences, and the general feeding water temperature difference should not be greater than 3 degrees.
