This is because of the water quality. If the water quality is alkaline, the calcium content in the water is high, which is easy to cause lesions in the eyes of goldfish, similar to cataracts.
Infection can occur if the goldfish rub against each other or if the water quality deteriorates, and the goldfish will die. High chlorine levels in the water can also cause this condition, so it is recommended to leave one-third of the old water and two-thirds of the new water when changing the water, and not to use new natural water. Spend a day or two in the sun.
There are generally two scenarios:
1. Cataract, white spots in the eyes, belongs to vitamin A deficiency, poor feed, lack of nutrition, lack of evidence, can still see and eat at the beginning, the more regret comes, the more serious, it is invisible. Vitamin A supplementation will provide relief.
2. A layer of white membrane on the outside of the eye, which is obvious. It is a bacterial infection, some people call it blindfolding, the water quality is poor, the harmful bacteria exceed the standard, and the medicated bath sterilizes. If there are snails in the tank, there may also be parasitic complications.

Goldfish have white spots on their tails because they have white spot disease. This is a disease caused by small melon worms, which is relatively harmful and contagious. When a goldfish gets sick, not only white spots will appear on the tail, but also the entire body will be covered with white spots.
This disease is common in spring, autumn, and during the rainy season. After finding that the goldfish is sick, the water temperature should be raised to 25-28 degrees to inhibit the growth and reproduction of small melon insects. In severe cases, mercurous sulphate medicated baths** can be used.
When farming goldfish, some white spots on its tail are sometimes observed. The reason for this problem is that they have white spot disease. The disease is caused by a protozoa called a melon worm. They can invade the ** or gills of goldfish, causing goldfish to become sick.
When a goldfish is sick, it will not only find some white spots on its tail, but also slowly the whole body of the fish will be covered with white spots. This disease is more common in spring, autumn and the rainy season, especially when the water temperature is 15-23 degrees, and it is most suitable for the growth and reproduction of small melon insects. The disease itself is very harmful, and the mortality rate is very high, and can even reach 70%-80%.
Moreover, it is contagious, and if kept in groups, it can quickly lead to the death of most individuals in the stock.
1. If the situation is more serious, it is best to use medicine. It is relatively easy to buy drugs specifically for this disease in aquariums. It is also possible to take a medicated bath with a solution of mercurous sulfate**.
2. After finding that the goldfish has white spot disease, the water temperature needs to be appropriately raised. Because the suitable temperature of the melon insect is 15-23 degrees, the temperature can be adjusted to between 25-28 degrees, making their living environment unsuitable. However, it is not possible to increase the temperature suddenly, which can cause discomfort in the goldfish.
Therefore, the temperature needs to be raised slowly.
3. In addition, special attention needs to be paid to water quality. Poor water quality is one of the causes of this disease. Each time you change the water, you can replace about one-third of it, not too much.
Inject new water not too quickly. In addition, some fungicides and other substances can also be mixed to prevent this disease.

1. White spots on the tail of goldfish may be goldfish white spot disease.
2. Goldfish long white spots are generally due to sudden changes in the environment of the fish tank, which makes the goldfish not adapt to the environment and get sick, so that the resistance of the goldfish is reduced and infected with white spots. Or the newly added fish itself has white spots and passes on to other goldfish.
3. Treatment methods for white spot disease:
1) White spot bacteria are afraid of high temperatures.
First of all, the water temperature of the fish tank is raised to 25 28 degrees, of course, it cannot be heated quickly, the goldfish will not adapt to the heating too fast, we can use a heating rod with lower power to heat slowly, generally 2 3 degrees per hour The heating rate.
2) Partial water change.
It is possible to replace 1 3 water in the fish tank. Change the water slowly, first slowly remove the water from the fish tank1 3. Then slowly pour in fresh water that has been cooled. The rate of filling new water must be slow, and the water temperature in the tank should not change by more than 1 degree.
3) Use special drugs for white spots.
If the goldfish is not too severe, after the first two steps of treatment, the white spots will disappear in a week. If the white spots are more serious, you need to use the medicine, and the potion clusters for the treatment of white spots are sold, and you can buy it back and use it according to the requirements of the instructions. When the white spots of the goldfish disappear, you need to change the water once a week to slowly remove the medicine from the tank.
Goldfish. Originating in China, goldfish is also known as "golden crucian carp", which is similar to the carp (cyprinus carpio) but has no mouth whiskers, and is an ornamental fish that evolved from crucian carp. There are many varieties of goldfish, the colors are red, orange, purple, blue, ink, silver-white, five-flower, etc., which are divided into four categories: literary species, grass species, dragon species, and egg species.
Goldfish are best raised in a glass tank or aquarium 25 to 30 cm deep, raise water before raising fish, the water temperature suitable for goldfish is 20 28 degrees, and the pH value is. Goldfish can be fed with goldfish feed, supplemented by bloodworms, bread, etc. In addition, the owner needs to change the water regularly and test whether the water quality is stable. >>>More

The bitten goldfish got sick with a rotten tail.
Other fish are afraid of being infected, so they bite it and want to eat it, and the disease will not be contagious, which is a cleaning mechanism of nature, just like a vulture eating a dead corpse, which plays a role in preventing the spread of germs. Don't give medicine to the fish when it's okay, it's poison and it will poison the fish. You can put some large salt for fish farming in the tank (sold in fish shops), which can kill bacteria and prevent diseases. >>>More
