There are generally three reasons why the fishtail is complete. The first is the embryonic period, because the incubation conditions are poor, which leads to its abnormal development. The second is that the feeding management is not in place, which leads to fish being stimulated or poisoned, leading to bending. The last one is caused by parasites, which destroy the nerves or brains of fish and cause the body to distort. According to different situations, the treatment methods are different. First, what is the reason for the fish tail bending? There are generally three reasons why the fish tail is complete. The first is the embryonic period, because the incubation conditions are poor, which leads to its abnormal development. The second is that the feeding management is not in place, which leads to fish being stimulated or poisoned, leading to bending. The last one is caused by parasites, which destroy the nerves or brains of fish and cause the body to distort. According to different situations, the treatment methods are different.

Second, how to treat the fishtail bend 1 and change the water in time: the first thing to do after finding the fishtail bend is to change the water in time. Because the content of ammonia nitrogen in water is too high, it is easy to cause this symptom. By changing water, the content of harmful substances can be reduced, which will play a certain role in the recovery of fish.

2. Pay attention to the water temperature: As a temperature-changing animal, fish have very strict requirements on the water temperature, and the daily temperature change cannot exceed 2℃. At the same time, low temperature will also stimulate the fish, and the fish will bend its tail. Therefore, it is necessary to control the water temperature to ensure that the temperature is suitable for the growth of fish.

3, drug pest control: if the tail is bent caused by parasites, the treatment method is to use drugs to kill insects. Usually choose Dabai tablets, the therapeutic effect is more significant, but the price is also more expensive. If the fish is not very expensive, it is not recommended to treat it, and it will be more cost-effective to replace it.
