1. The water quality is too poor 1. Reason: The congestion of goldfish may be caused by poor water quality. If the breeder breeds goldfish in an environment with poor water quality for a long time, their skin will easily become congested. In addition, if there are too many harmful substances in the water, it is easy to cause congestion.
2. Solution: Breeders need to change their water first to keep the water clean. If there are injuries or infections on the body surface, the breeder needs to add some crude salt to them to avoid decay.
2. The temperature difference is too large1. Reason: The congestion of goldfish may also be caused by the temperature difference, although they can grow in lower or higher water temperature. However, if the temperature suddenly changes too much, it is easy to stimulate goldfish, resulting in congestion on their body surface.
2. Solution: It is best for breeders to install a heating rod to keep the water temperature in a stable range. As long as the water temperature is stable, they will gradually recover.
3. Congestive disease1. Reason: Goldfish may suffer from congestive disease due to parasites or wound infection. When parasites parasitize on the body surface for too long, their bodies are prone to congestion.
2. Solution: The breeder needs to clean up the parasites visible on the body surface first, and then use potassium permanganate or malachite green solution to give the sick fish a medicinal bath. Take a medicated bath every other day for 20 minutes.
