Many fish diseases, such as erecting scales and rotten fins, can cause the scales of goldfish to fall off. In this case, the goldfish needs to be treated immediately according to the specific symptoms. Usually at this time, the sick fish should be fished out and treated separately to avoid infecting other goldfish. If the water quality is very poor, the water should be changed in time and the fish tank should be disinfected. When the sick fish is treated alone, the water temperature can be raised and the water can be continuously oxygenated, which is more conducive to the recovery of the goldfish. The drugs used for different diseases are different, but the longest used drug is oxytetracycline, which can be used for almost all fish diseases caused by goldfish infection. Medicated bath with 5 ppm oxytetracycline solution is more effective, and the goldfish should be given medication until the disease is cured.
