What reason is goldfish body has white dot dot, how to treat

Heating medicated bath: The white spots on goldfish may be due to white spot disease. At this time, the water temperature can be raised to above 28 ℃ first, and then the sick fish can be soaked with 2ppm mercurous acetate. Clean water quality: It is also possible that poor water quality leads to a large number of germs. At this time, it is necessary to change a small amount of water and adjust the water Reduce the feeding density: It is also possible that the feeding density is too high, which leads to their fighting injuries. At this time, take out a part of the fish and smear the wound of the sick fish with yellow powder.

1. Warm-up medicated bath

1. Reason: When goldfish are infected by small melon worms, they will suffer from white spot disease. At this time, we can observe that there are white dots on them. White spot disease is contagious, so it can't be kept

2. Treatment method: Isolate diseased goldfish from healthy fish, because white spot disease is contagious, so they can't be raised together with healthy fish. Then slowly raise the water temperature to above 28 ℃ to kill the small melon worms in the fish tank. Then soak the sick fish with 2ppm mercurous acetate for 2-3 hours every day, and then recover after a period of time.

2. Clean water quality

1. Reason: When the water quality is too poor, parasites and germs in the water will multiply. At this time, they will not only infect goldfish, but also compete with goldfish for oxygen, resulting in white spots on goldfish.

2. Treatment method: Take out a quarter of the water in the fish tank, and then pour the tap water with temperature rise, PH adjustment and chlorine removal. Then add a certain amount of crude salt to the fish tank, and adjust the concentration in the fish tank to 1% to sterilize the fish tank. Finally, oxygen is injected into the fish tank to increase the oxygen content in the fish tank.

3. Reduce the feeding density

1. Reason: When there are too many goldfish in a fish tank, they will rub against each other when swimming, and they will also fight for living space, resulting in body surface damage.

2. Treatment method: Take out a part of fish in the fish tank to reduce the feeding density. Then separate the sick fish from other fish, and apply yellow powder to the wound of the sick fish.
