What is the reason why the koi fish keep rolling in the fish tank?

Koi. Eat Dora.

If the fish poop is not treated in time, some fish poop will dissolve in the water, and if there is a lack of nitrifying bacteria in the tank.

There are very few nitrifying bacteria in the epiphytic area, and the fish feces cannot be treated in time, which makes the ammonia content in the water body increase and the water is easy to be turbid. Fish live in ammonia-poisoned water for a long time, and their physique will gradually become weak, and they will be easily attacked by viruses in the water. Some hazards do not manifest themselves all at once, but have a process of accumulation, which generally starts with fish with weaker constitutions.

Therefore, the key to raising good fish is filtration, and filtration is mainly to filter fish feces, the toxins in the water are produced by fish feces, and only by removing the ammonia of fish feces, the water will remain clear and non-toxic fish can be healthy and less sick.

There may be the following reasons why koi fish keep tumbling in the fish tank:

1.Koi fish are infected with arrowworm disease, which can have an effect on the surface of the fish, causing the fish to tumble.

2.Problems with the water quality in the fish tank, such as too high nitrite concentration, abnormal water temperature (too low or too high), or low dissolved oxygen in the water body. These factors can bring unhealthy behavior to koi fish, including weak swimming or even hovering, unable to swim only on the surface of the water, and rolling behavior after koi are infected with diseases.

3.Changes in the water body after autumn may also trigger koi tumbling behavior.

If koi fish are found to have this abnormal behavior, it is recommended to take it to a pet hospital for diagnosis and **.

Generally, koi fish with parasitic diseases will have the performance of rolling and irritability, such as iodobubble disease fish will swim wildly in the water, circle or burrow into the water and jump up. Fish with three generations of worm disease show extreme restlessness, sometimes swimming wildly in the water, sometimes sharply sideways. As if to get rid of something.

There are also parasites such as ringworm disease and ichthyosis that can make fish very painful. Iodobubble disease is generally used to clean the pond thoroughly with quicklime and soak the fish with potassium permanganate solution. The three generations of worm disease, ring worm disease, and fish fish disease are killed by splashing the whole pond with trichlorfon, and the fish fish disease should be plucked with tweezers.

Koi rollover may be caused by swim bladder disorder, pay attention to the water temperature of the koi living environment, and also pay attention to the water quality.

Fish bladder disorder is a non-communicable fish disease that occurs only in winter, most commonly in transparent fish that are sensitive to the cold. In the past, it was only seen in goldfish cultured in aquariums, but now it is also found in carp and grass carp cultured in ponds, and the main symptoms are: diseased fish can not maintain balance in the water, or lie on their sides, or stand upside down, or even belly up, floating in the water or sinking to the bottom; Dissection reveals atrophy or ulceration of the swim bladder.

It is generally believed that it is caused by the low water temperature, the poor cold tolerance of the fish, especially the loss of the ability of the swim bladder to adjust the balance when encountering severe freezing.

Koi fish that have become sick need to be kept in isolation or in small cages that float on the water. The water level should not be too high, as long as it can not pass the body of the fish. If the water temperature is below 20 degrees Celsius and the isolation tank is not too small, there is no need to use oxygenation facilities, which reduces the energy consumption of koi swimming passively.

And add one-thousandth of coarse salt to the water to inhibit the growth of pathogens in the water. And slowly raise the water temperature to more than 15 degrees.

In the early stage of the disease, you can change to feed some green feed, such as duckweed. At first, koi may not like to eat much, but after 2-3 days of stopping feeding other feeds, koi will get used to it. Generally, the koi will return to normal in about a week.

For koi fish with imbalance caused by gastrointestinal obstruction, you can refer to the ** method of enteritis.

For severely ill fish, if it is lying on its side on the surface of the water, a small syringe can be inserted into the swim bladder from the side of the body to extract part of the gas. Alleviate symptoms. (This requires familiarity with the anatomy of different koi species and is risky.)

For sick fish lying on their side on the surface of the water, styrofoam can be tied to the dorsal fin to make the sick fish stand upright and suspended in the water. Fingerlings without dorsal fins can be isolated from the bottom of the tank in small cages. For severely ill fish that have passed through the above**, they can live for about a year at most.

The temperature and quality of koi fish should be strictly controlled.

Summary. Because individual fish are timid and have this phenomenon, the other is that they have parasitic diseases, and they relieve pain by swaying from side to side.

Dear, hello, the koi fish horizontal tank swaying from side to side may be caused by several reasons: the water in the fish tank has not been changed for a long time, and the water quality has deteriorated; The fish tank was not disinfected and sterilized, and bacteria were generated; The new koi fish are put into the fish tank without passing through the water, because the water limb wheel temperature in the bag and the water temperature in the tank are different, the koi fish do not adapt to the water temperature and environment, which will cause the phenomenon of lying in the tank.

Only one of the three fish is like this.

If so, it may be frightened, or it may be parasitic.

Because individual fish are timid and have this phenomenon, the other is that they have parasitic diseases, and they relieve pain by swaying from side to side.

Koi tumbling in the water may be due to the disease of arrowworm, which is generally more susceptible to it when farmed outdoors, and the main pathogen is arrowworms. In this case, you can use sterilization water to take a medicated bath on the diseased fish, and the medicated bath can be done twice a day, about 10-20 minutes each time. It may also be because of too much water change after autumn, and the koi are not suitable for the car.

In this case, you can first increase the temperature of the water tank to 25 degrees, and then maintain a good water quality and let the koi recover on their own.

1. Arrowworm disease.

1. Reason: The main cause of arrow worm disease is unsuitable environment or unclean water quality. Koi carp that have just been transferred from a wild fish pond to a captive-bred fish pond or fish tank are more susceptible to this disease.

The symptoms of sick fish are restlessness, frantic swimming in the water, tumbling back and forth, and rubbing against the tank. Diseased fish will have filamentous parasites on their backs or fins, and in severe cases, they will also have filaments in their mouths and gills.

2. **Before closing the letter: you can use trichlorfon for a medicated bath, and the medicated bath can be used for 20 minutes. Then sprinkle 1-2g of dichlorex into the fish tank once a day for 7-10 days.

Note that the first three days of trichlorfon and trichlorfon can be used at the same time, and the effect will be very significant. After 3 days, one of the drugs can be selected to continue until the koi recovers.

2. Alternation of seasons.

1. Reason: Changing too much water or too much temperature difference during the change of seasons will cause koi to have a stress reaction, such as rolling in the water, hiding at the bottom of the tank, and scurrying back and forth. This usually happens after the beginning of autumn, when the weather is cooler.

2. Method: If the koi will not hurt themselves if they roll back and forth in the water, they do not need to be drugged. Just keep the water temperature at 25 degrees, keep the water clean, put some coarse salt in the fish tank, and finally wait for the koi to recover on their own.

When the winter comes, the keeper should take precautions in advance to avoid the recurrence of this situation. If the condition is more serious, or if you are infected by bacteria, you can use the corresponding fish medicine**.
