How to treat koi fish when they always rub the bottom of the tank

Retreating fish when there is a disease is a symptom rather than a root cause, and it is not easy to cure. Fish diseases are mainly caused by long-term poor water quality, just like people, if they live in an environment with poor air for a long time, they are also prone to get sick. The key to raising fish is filtration, filtration is to filter fish feces, the toxins in the water are produced by fish feces, and only by removing the ammonia of fish feces can the water be stable and clear, and the fish can be healthy and less sick.

If the filtration effect is not good, the ammonia content of the water body will be high, and the fish will live in the water body with ammonia poison for a long time, and the body will gradually become weak, and it will be easily attacked by the virus 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. Yongqing filtration understands that this filtration system has the function of automatically cleaning fish feces, which will help.

Here's why:

1. In the process of koi breeding, when the koi fish feels itchy on their bodies, the koi fish will rub against the tank. For example, skin mold, the koi carp with skin mold will not only rub the tank, it will also show irritability, swimming disorders, loss of appetite, if not timely, it will lead to emaciation and death. And when you observe it with the naked eye, you can see that the tissues of the affected area are red and swollen, and a clump of hairy hyphae grows, which is white or gray-white and flutters in the water, which is easy to identify.

Because the fish is sick: first observe the fish, know what the disease is, usually not due to stress of rubbing the tank, the disease will come out soon after rubbing the tank, **disease is**rubbing the tank, after establishing**, it is best to isolate, so as not to infect other fish.

2. When there are parasites on the koi's body, they will rub the tank, such as fish lice, fish monsters, melon insects, three-belt insects, ring worms, wheel insects, etc., the appearance of these parasites will make the koi feel very uncomfortable, so they will rub the tank. We routinely carry out sterilization and insecticide, and sometimes even the fish are fine, but the sterilization and insecticide are rubbed into the tank. The reason is that the insect fungus is on the fish, and the insecticidal fungus reacts, which naturally causes the impact on the koi, and the fish is uncomfortable, so it rubs!

3. Stress, new fish going into the tank, changing temperature, excessive water change, etc., will cause fish discomfort and cause stress. (The mucus of the fish body increases, and other fish may chase and bite at this time, which is a normal phenomenon, and the fish will eliminate the diseased body and reduce the risk of contracting the disease itself).

Due to temperature change: Be sure to keep the water quality stable and burst oxygen.

Due to excessive water change: Keep the water quality stable. Nitrifying bacteria can be added to detonate oxygen.

Because the new fish is in the tank: (here refers to the old fish) can add vitamin C, or add salt to 1000 parts 3 (salt changes the osmotic pressure to make the fish comfortable), and the oxygen is burst. (here refers to the new fish) the new fish will definitely have some stress reaction when they come back, because the original water quality must be different from the current water quality.

Therefore, it is often said that why the new fish come back, pass through the water, and then temporarily raise for ten to fifteen days before closing the tank, this is the reason. (In fact, even if it is temporarily kept for 15 days, there may be a little reaction in the closing tank).

If the fish does not accept the water, it needs to be more patient, and the time may last a little longer, in addition to the above-mentioned plus vitamin C, add salt to 1,000 parts three, and burst oxygen. It is also necessary to pay attention to the water change at the back to maintain the water quality, and replenish the salt to the limit after the water change.

Special attention: chlorine dioxide must be according to the amount of the instructions, it is better to use less than the next day, too much chlorine dioxide may cause the nitrification system to collapse. So why use chlorine dioxide, chlorine dioxide disappears quickly (it will be faster when oxygen bursts), and it does not affect the color of the water.

Because the fish is sick: Observe the fish first to know what the disease is. Usually it is not due to stress to rub the tank, and the symptoms will come out soon after rubbing the tank, and the disease is the cause of the rubbing tank.

The dosage must be accurate! The consequences are severe!!

There are generally two reasons:

1. If you have dermatomylosis, the koi carp with dermatomylosis will not only rub the tank, but it will also show irritability, swimming disorders, loss of appetite, and if it is not timely, it will lead to emaciation and death. The naked eye can see that the tissues of the affected area are red and swollen, and clumps of hairy hyphae grow, which are white or gray-white into cotton wool floating in the water, which is easy to identify.

2. There are parasites on the body of koi, such as fish lice, fish monsters, melon worms, three-belt worms, ring worms, wheel worms, etc., the appearance of these parasites will make koi feel very uncomfortable, so they will rub the tank. At present, the most common is melon worm disease, which is also a white spot disease, and its symptoms are white spots attached to the body surface, fins, and gills of koi fish, which are visible to the naked eye.

Sick fish are slow to react in the water, swim slowly, no longer eat, swim in groups by the side of the tank or float on the surface of the water, and will rub the four walls of the koi fish tank from time to time, and will soon die. However, white spot disease is also very good**, when the temperature reaches more than 28 degrees, the melon worm will die.

Try the old three things first, change the salt and water under the temperature If it is good, use some yellow powder to kill and sterilize, and see if there are any parasites on the surface of the fish, if there are some trichlorfon.

Watch and don't do anything for the time being.

Rubbing the tank is the fish tickling, just like the child scratching his head, you will not spray the child with insecticides and antibacterial drugs just because he scratches his head. Therefore, there is no need to filter the fish**, you just need to pay attention to observation, and if there is an infection, it is not too late to deal with it.

What a cylinder... Bring a lid** to buy it.

It's because there are bugs on the body, itchy.

Dear, hello, if you use medicine during insecticide, it will cause stress to koi, if it is caused by stress, it may also lie in the tank, you can take a look after a while. In addition, if the Qing Zhao Brigade is not caused by the stress of the stool, but due to the chain attack disease, this situation will also occur, take the Jinyu out and observe it to see if there are any wounds on his body, such as rotten tails, etc
