1. Reason: Small goldfish may suffer from white spot disease because of white things. The main reason for white spot disease is that the temperature difference is too large or the water temperature is too low. In the early stage of white spot disease, sporadic white spots will appear on goldfish, and in the later stage, when it is serious, the white spots will expand into white spots, which will eventually lead to their death.

2. Solution: If you want to treat white spot disease, you must first raise the water temperature to 28 ℃. In the high temperature environment, small melon worms can't survive. Secondly, it is to use Baidian Net to give sick fish a medicinal bath, which can relieve the discomfort of goldfish. Finally, keep the water clean and keep the environment stable, which can speed up their recovery.

1. Reason: Small goldfish have white things and may suffer from water mold. The main cause of this disease is bacterial invasion. For example, the poor water quality in the fish tank or trauma will lead to bacteria invading the fish. Water mold is not obvious in the early stage, but serious in the later stage, water mold will grow out of fish.

2. Solution: Breeders need to isolate sick goldfish first, so as to prevent them from spreading to other fish. Then install an ultraviolet germicidal lamp and turn it on for 3-4 hours every day, which can kill bacteria in the fish tank. Finally, use potassium permanganate medicated bath, adhere to the medicated bath for one week, and the water mold can be cured.
