Why do koi fish keep jumping out? What causes koi fish to jump out of the water?

How big an aeration pump is needed for a fish pond with four tons of water.

Koi have a large oxygen consumption, such as raising in aquariums or other small containers, the feeding density is large, and koi fish like to jump out of the water in an environment where oxygen is insufficient. You can put some aquatic plants to photosynthesize under the sun, and see that the aquatic plants spit out small bubbles.

It is also possible that there are parasites in the body of the fish, which can make the fish irritable and very likely to jump out of the water. Carefully check the surface of the fish for parasites, and if so, buy fish medicine to soak.

It is also possible that there is too little water, and if there is less water, the fish will also jump out of the water due to the proximity limit. If the tank is high, there is no need to worry about the fish jumping out if there is too little water. If the water is too full, the fish will jump out of the tank.

Solution: Put the water in the fish tank to a certain level. Put a lid on the fish tank, preferably the ventilated kind.

Solution:

1. Cleaning and disinfection of koi. Generally, before the koi fish enter the tank, the fish should be washed and disinfected.

2. Add sterilization water or medicated bath For koi carp that have been infected with parasites in the tank, you can add sterilization water to the fish tank, or you can use a separate medicated bath for koi fish to prevent koi fish from being infected by bacteria.

3. Keep the dissolved oxygen content sufficient. Keep the amount of dissolved oxygen in the water sufficient, if it is a cloudy day, the possibility of hypoxia skipping is very high, if necessary, you can buy an aeration equipment and fill it frequently.

4. Adjust the breeding density, and the density should not be too large.

5. The feeding water should not be too little or too full, usually the feeding water is put to a certain water level, not easy to be too low and not too high, the lowest water level is twice the height of the fish, and the highest water level is 5-10 drop from the tank mouth.

This situation is called "koi jumping tank".

Reasons why koi fish jump tanks:

1. When the amount of dissolved oxygen in the water is very high, the koi will be highly active and jump out of the tank, otherwise there will be a saying of "carp strip dragon gate".

2. Change in feeding habits. Some koi fish have formed a fixed feeding habit and will jump if they are not fed by the feeding time.

3. Adaptation to the new environment. Mainly when the newly entered koi fish.

4. Be frightened. Koi fish are very timid, and they are generally easily frightened and jump out of the tank when fishing for fish to change water.

5. There are parasites on the fish. If the body of the fish is parasitic, it will make the fish irritable and will also jump out of the tank.

6. The oxygen content in the water is not high. Koi fish are most likely to jump out of the water when they are not oxygen-deficient.

7. The density of fish farming is too large and the space is too small. If the density is too high, the koi fish will not have enough space to move and will also jump from the tank.

8. There is too little water in the fish tank. If there is too little water in the tank, the koi fish will be limited because there is not enough water and will jump from the tank.

9. The fish tank is overfilled. For fish tanks, if the water is too full, the koi fish are easy to jump out of the tank due to their nature and love to jump over.

Koi jumping tank treatment method

1. If the fish just jumped out and is still bouncing on the ground, it should be immediately put into the original pool water, and the amount of dissolved oxygen in the water should be tested.

2. If the fish is no longer bouncing, but the mouth is still open and closed, quickly take the original tank water and add half of the new water to pour it into the shallow basin, and use the air pump to oxygen, then the fish can still breathe on their own, most of them can recover on their own, but pay attention to the breathing rate, and consider artificial respiration if you find that the breathing is getting weaker.

3. The fish does not struggle on the ground, nor does it breathe, so it has been suffocated for a long time, but do not give up, the first thing to do is artificial respiration, if after a period of time, the fish has weak breathing, it should be put into the basin, immediately use the air pump to oxygen, and wait for the fish to recover on its own.

4. After the koi carp jumped out of the tank for treatment, it must be rested in a shallow basin for three or four days, do not feed it for the first two days, and feed some high-protein and nutritious koi feed for the next two days, but it must be a small amount to supplement physical strength and be more conducive to recovery.

Koi fish suddenly scurry, probably because they were scared. At this time, the koi should be allowed to rest and feed on time. It may also be due to the unsuitable water environment, such as poor water quality, unsuitable water temperature, and insufficient oxygen.

At this time, it is necessary to pay attention to keeping the water clean, adjust the water temperature and oxygen content of the water, and be careful not to change the water suddenly and in large quantities. It is also possible that the koi fish are sick. At this point, the sick fish should be fished out separately**.

1. Reason: Koi are timid, easily frightened when they see strangers, and are also sensitive to red. Fish that are new to the tank are also easily frightened when they are unfamiliar with the environment.

2. Solution: When the koi are frightened, just let them rest and feed on time.

1. Reason: The water quality deteriorates or a large amount of water is suddenly changed, which will make the koi fish not adapt to the water quality and run around. The water temperature is not suitable or because there are too many fish in the tank, and the oxygen is insufficient, which can also cause the koi to run around.

2. Solution: Keep the water quality clean and replace part of the water body when changing the water. Adjust the water temperature to reduce the number of fish in the tank. Adjust the wattage of the oxygen pump to increase oxygen.

1. Reason: Koi may run around because of pain after being injured. If there is no external injury, it may be due to an infection with parasites or bacteria inside or outside the body, which makes the body uncomfortable and scurry.

2. Solution: Fish out the sick fish and separate it. In addition, the water in the original tank also needs to be replaced and sterilized.

Generally speaking, koi fish do not jump from the tank, if there is a lack of oxygen, they will jump, and there is a situation where the golden koi fish like to jump, which is the so-called carp jumping dragon gate. So it's best to add a lid when raising koi fish in a fish tank, I saw it on the Huawang fish, you can go and see it if you need to.

The reasons why koi fish jump out of the tank are as follows:

1. The fish tank is too small and does not have enough space to grow and swim, resulting in koi repeatedly hitting the wall.

2. The koi is frightened, and if the koi is frightened, it will lead to nervousness and jumping out of the tank.

3. The water quality is not good, the water quality is turbid, or the oxygen content in the water is not high, and there are too many bacteria and parasites, which will cause the koi to jump the tank.

When raising koi, we must prepare a perfect fish tank, the fish tank must prepare a lid, and ensure that the water quality environment is stable and healthy, and at the same time ensure that there is enough dissolved oxygen in the fish tank to ensure that the koi have a healthy living environment, then the koi will not jump out of the tank.

Koi

Koi, a carp of the family Cyprinidae, is a high-grade ornamental fish, known as "a living jewel in the water" and "a work of art that can swim". Koi fish can be up to 1 to 1 meter in length, distinguished by different colors, patterns and scales, mild, like to swim in groups, easy to raise, and have strong adaptability to water temperature. It is widely distributed in China, Russia, Europe, North Korea, Japan, etc.

Koi are omnivorous. Koi fish are gentle by nature, like to swim in groups, easy to raise, and have strong adaptability to water temperature. It can live in a sleepy 5 to 30 water temperature environment, and the water temperature of growing is 21 to 27.

In addition to the water temperature and the abundance of bait can affect the growth rate of koi, there is also a large difference in the growth of female and male fish. The age of a koi fish is determined by the number of rings of the scales, which indicates the age of the koi.
