After the fish get white spot disease, the first thing to do is to change the water in time. Improving the water quality is helpful to the recovery of the fish. The difference between changing water in peacetime is that at this time, water should be changed frequently, even if the water body is not muddy, it should be changed every other day, but not more than one fifth each time.
White spot disease is caused by the Ichthyophthirius multifiliis, a parasite that cannot tolerate high temperatures. It usually stops growing if it exceeds 25 ℃, and dies in large numbers if it reaches 28 ℃. It should be noted that the temperature should not be raised rapidly, otherwise the temperature fluctuation will cause some stimulation to the fish.
In order to prevent fish from being invaded by other bacteria after suffering from white spot disease, which will lead to more serious diseases, it is necessary to properly salt. The concentration of salt should generally be controlled at about three thousandths, not more than five thousandths. It should be noted that salt should not be used as far as possible, and iodine-free must be used.
To prevent the occurrence of white spot disease, first of all, we must ensure the safety of the water source. If we use water from an unknown source, it may introduce small melon insects into the tank, causing the fish to get sick. At ordinary times, we should also pay attention to heat preservation, the temperature is constant at about 25 C, which can ensure that we will not get sick.
