What to do if the back of a goldfish is rotten

If the tail of the fish is rotten, you can use anti-inflammatory drugs such as yellow powder and gentamicin for medicated baths.

After finding that the fish tail is rotten, the owner should immediately isolate the sick fish**, first change the water, increase the water temperature at the same time, and then add an appropriate amount of coarse salt to the water for disinfection and sterilization.

The phenomenon of rotten tails in fish is mostly due to the influence of water quality and water temperature, so the owner should pay attention to controlling the water temperature and water quality when raising fish, especially when changing the water, the temperature difference before and after the water change should not be too large, otherwise it will affect the health of the fish.

The tail of the fish has the role of controlling the direction. In order to adapt to life in the water, most fish have a fan-like tail shape, and when they swing vigorously, they act like a propeller to push their body forward, and at the same time, the tail of the fish can control the direction and act as a rudder. The tail of the fish determines the direction of movement, provides forward momentum, and if lost, the fish will not turn.

If you turn the earth's calendar back to three or four billion years, there were no whales, no tigers, poions, bears, hippos, penguins, albatrosses, chimpanzees, monkeys, and no one on the earth, but there were already fish on the earth. Fifty million years ago, one of the bony fishes, relying on two pairs of bones to support fins and breathing holes that lead directly to the lungs, finally managed to leave the sea and land after millions of years of arduous and continuous efforts.

White spot medicated bath: The rotten body of the goldfish may be due to white spot disease, and the symptoms of ulceration of the fish body will appear in the middle and late stages of this disease. If the goldfish is found to have festered, the keeper will need to use a white spot medicated bath**.

Malachite Green Medicated Bath: Goldfish suffer from water mildew, and the fish body will also fester, and the keeper will need to use the Malachite Green Medicated Bath**. Oxytetracycline medicated bath:

It is also possible that the goldfish is rotten because of rotten fins, and at this time it is necessary to use oxytetracycline medicated bath**.

1. Reason: Goldfish may have white spot disease if it is rotten, because when the symptoms of white spot disease are more serious, the fish body will ulcerate. White spot disease is mainly caused by low water temperature or too large temperature difference, and small melon insects have an environment to reproduce.

2. Method: If the body of the goldfish has been ulcerated, it means that the symptoms of white spot disease have been more serious. At this time, the keeper needs to raise the water temperature to 25-28 first, and then use the white spot net for a medicated bath, about 15 minutes a day, and insist on improving for a week.

1. Reason: The ulceration on the goldfish may also be caused by water mold, which is mainly caused by the invasion of mold spores caused by external injury. In the early stage of water mold disease, white flocculent matter will appear on the diseased part, ulceration will appear in the middle stage**, and ulceration will become larger and larger in the later stage.

2. **Method: Breeders can use malachite green medicinal bath first, and if the symptoms are more serious, they can be matched with methyl blue. Generally, 100 kg of water is put in malachite green or methyl blue, and the diseased fish are medicated for bathing, and the medicated bath is 10-20 minutes a day, and the mycelium will fall off on its own after a few days.

1. Reason: It is also possible that the goldfish is rotten, mainly caused by poor water quality. Rotten fin disease usually occurs in the fin area of the fish, and only spreads to the fish when the symptoms are more severe.

2. ** method: the keeper can first use salt water to clean the diseased fish, or use oxytetracycline to give the diseased fish a medicated bath, and can also soak the diseased goldfish with a low concentration of potassium permanganate.

Maybe it's because of rotten fins.

Solution: Once this situation is discovered, it must be isolated immediately, and then antibiotics or drugs such as tintle yellow must be applied to ** the diseased fish. If the symptoms of rot are slow, the best way to do this is to replace some of the water in the tank, clean the filter and add a little salt to the tank, and stop feeding for a few days.
