1. Excessive temperature difference: If the temperature difference between day and night is too large, or the temperature difference between the newly added water and the water in the original tank is too large, the guppy's constitution will weaken, and it will be infected by bacteria and suffer from needle tail disease.
2. Bacterial infection: The guppy's tail is infected by bacteria, which will cause muscle contraction and cause needle tail disease.
3. The water quality deteriorates: The water quality deteriorates because the fish tank is not cleaned or the water is not changed for a long time, which will cause the guppies to get needle tail disease.
4. Insufficient oxygen: The density of the fish in the tank is too high. Insufficient oxygen will lead to anoxia and weakness of the guppies, resulting in needle tail disease.
After discovering that guppy needle tail disease, we should quickly fish out the sick fish and isolate them separately, and put them in water with penicillin and coarse salt for medicinal bath treatment. A heating rod should be placed in the treatment tank, and the water temperature should be set between 28 and 30 degrees, below which it will be automatically heated. We need to strengthen the current and make the guppies move. Normal feeding is also required to ensure the physical strength of guppies. In addition, the original tank also changed 80% of the water, and put coarse salt for sterilization, so as to avoid the spread of bacteria.
