fish is because it has white spot disease. White spot disease is a parasitic disease. The pathogen is a parasite called Ichthyophthirius. It usually parasitizes the fins or gills of fish. After the disease, white spots will appear. At the same time, the fish's spirit is depressed, they seldom move, and they will rub their bodies beside the sand and gravel of aquatic plants. If the disease is serious, it will stop eating, have difficulty breathing, and even die directly.
white spot disease 1. Raise the temperature: To prevent white spot disease, first of all, we should pay attention to the water temperature. This disease is easy to catch in late autumn and early spring. At this time, the temperature is relatively low, and it is not easy to find after Ichthyophthirius parasitism. To avoid the disease, we need to keep the water temperature at about 25 degrees Celsius. This can play a preventive effect.
2. Change water regularly: Fish suffer from white spot disease, mainly because the water quality is not good, which gives Ichthyophthirius living space, so we must change water regularly. Change the water according to the temperature to adjust the cycle, generally in summer can be changed every three or five days, in winter only once a week or two, change too frequently will stimulate the fish.
3. Sterilization and disinfection: If you pay attention to sterilization and disinfection at ordinary times, it can also play a certain preventive effect. Every once in a while, it is better to disinfect the fish body or irradiate it with a germicidal lamp, but the time should not be too long, otherwise the beneficial bacteria will be destroyed, so that the survival of the fish will be affected.
