to do? After discovering small fish gets white spot disease, need to isolate its in time, lest it infects healthy fish. After that, we should pay attention to changing water, so as to improve water quality, avoid aggravation of the disease, and at the same time, raise the water temperature. The pathogen of white spot disease is Ichthyophthirius, which is more sensitive to temperature. Usually when the water temperature reaches 25 C, it will stop growing, and when it reaches 28 C, it will die, so as long as the temperature rises, it can play a therapeutic effect.
1. Keep the water temperature: The best way to prevent white spot disease is to keep the water temperature. As mentioned above, Ichthyophthirius has poor tolerance to high temperature, so by keeping high water temperature, it can play a very good preventive effect, and high temperature can also accelerate the metabolism of fish, which can improve its resistance.
2. Regular water change: Regular water change can not only maintain water quality, but also help the health of fish. Usually every five to seven days, you can change a quarter or a fifth at a time. Changing too much can also cause some irritation to the fish. In addition, it should be noted that the temperature should be consistent before and after the water change.
3, pay attention to disinfection: fish is not sick, generally do not need disinfection, improper use of drugs may cause phytotoxicity. But anything that enters the fish tank must be disinfected first, especially when new fish enter the tank, if not disinfected, it is likely to bring in parasites, causing the fish in the tank to get sick.
