1. Change water and add salt 1. Reason: The rotten tail of grass goldfish may be due to poor water quality. Although they are not strict with water quality, when the water quality of their growth is too poor, the rotten tail will appear.
2. Treatment: Breeders need to change water immediately to keep the water clean. Then add some crude salt to the water, which can prevent bacteria in the water from infecting their tails again. If the unfinished tail of grass goldfish is not serious, it can be recovered in 3-5 days.
2. Furacilin powder bath1. Reason: The rotten tail of grass goldfish may also suffer from rotten tail disease, which is mostly caused by bacterial infection. After suffering from rotten tail disease, their tails will fester from the edge and eventually rot all the way to the bottom of the fish's tail.
2. Treatment: It is best for breeders to give them a medicated bath with furacilin powder or furazolidone once a day for 20 minutes each time. Finally, 0.01% potassium permanganate is sprinkled in the fish tank, and after about 7 days, they can recover.
3. Oxytetracycline and potassium permanganate medicated bath1. Reason: The rotten tail of grass goldfish may also be caused by post-traumatic infection, and their tails are fragile and easy to be injured. Once they are injured and not treated in time, their tails are vulnerable to infection.
2. Treatment: Breeders need to use oxytetracycline or potassium permanganate to give them a medicated bath. If the situation is not serious, 5 tablets of oxytetracycline can be added to 100 kg of water. If the unfinished tail is serious, 8 tablets can be added. Adhere to the medicated bath every day, about a week, the unfinished situation can be improved. If the tail has rotted to the root, the breeder needs to clean up the rotten part before taking a medicated bath.
