Koi body has white dot is how to return a responsibility, how to treat

Suffering from white spot disease: Koi may have white spot disease because of white spot disease. At this time, they can be isolated, dissolved with a small amount of mercurous nitrate in water, and given a medicated bath. Poor water quality: It may also be caused by poor water quality. At this time, you can change the water quality of the fish tank to reduce the content of germs in the water. Polyculture injury: It is also possible that when fish are mixed, they are injured by other fish. At this time, they need to be raised separately and sterilized with potassium permanganate.

1. Suffering from white spot disease

1. Reason: When koi fish are infected by white spot protozoa, they will suffer from white spot disease. White spot disease is contagious, and when they are raised together, white spot protozoa will infect other fish.

2. Treatment method: Fish out the infected koi and put it in a fish tank alone. Add crude salt to the original fish tank and adjust the concentration to about 1% to kill the white spot protozoa in the fish tank. Add a small amount of mercurous nitrate to the new fish tank and take a medicated bath for the sick fish.

2. The water quality is too poor

1. Reason: If you don't change water frequently or feed too much, it will pollute the water quality and lead to eutrophication. At this time, it can provide food for the reproduction of germs and parasites. When germs and parasites multiply, they will compete with koi for oxygen, causing them to have white spots on their bodies.

2. Treatment method: First, pour the water in the fish tank into a new fish tank, and scrub the original fish tank. Then take out a quarter of the original fish tank water, and add the treated tap water with little difference from the original fish tank water to the new fish tank. Finally, a filter system is added inside the fish tank to treat the water in the fish tank.

3. Polyculture injury

1. Reason: Many people like to mix fish when raising them, which plays a decorative role. But if they are mixed improperly, they will fight. Lead to injury and rot on the body surface of koi fish.

2. Treatment: Fish out koi to avoid being bullied by other fish. Feed the koi fish in a quiet place, and sterilize the wound with low concentration of potassium permanganate. After a period of time, it can be recovered.
