1. Cold 1. Reason: Goldfish may be sick, but cold is common. Goldfish are thermotropic animals. If the water temperature in which they live is too low or the temperature difference is too large, it will lead to diseases. Goldfish will suffer from loss of appetite and decreased activity in the early stage after catching a cold, and handstand and head planting will occur in severe cases.
2. Solution: Breeders need to keep the water temperature at about 22 ℃. If the weather is fine, goldfish can be exposed to the sun for a while. And use baking soda and salt to take a medicated bath for sick fish, and then put it into still water for about 15 minutes.
2. Scalding tail disease1. Reason: Goldfish may also suffer from scalding tail disease, and the main reason for this disease is that the water surface temperature is too high. This kind of situation is more common in spring and summer. The temperature on the water surface is very high by the sun. When goldfish swim from the bottom of the tank to the water surface, because its tail is delicate, it will be burnt out with many small blisters. Because these blisters are concentrated on the tail, goldfish can't control their balance.
2. Solution: The breeder needs to squeeze the blisters on the goldfish tail first, and then apply erythromycin ointment to the tail. Apply it once a day, and stick to it for one week, which will relieve the hot tail.
3. Fish body imbalance1. Reason: Goldfish head may also have fish body imbalance, mainly because the water temperature is too low. There are also some congenital fish imbalance.
2. Solution: Breeders need to raise the water temperature to about 25 ℃ and lower the water level to avoid them standing upside down and lying on their sides. However, this disease is difficult to treat, and breeders need to be psychologically prepared.
