Fish long white spot is generally suffering from water mildew or white spot disease. If the white spot is relatively small, completely adsorbed on the body surface, it should be white spot disease, and white spot flocculent, that is, hyphae, that is, saprolegniasis. These two are generally caused by low temperature, bacteria or parasites invade the fish, leading to disease. Therefore, we must pay attention to heat preservation at ordinary times, so that we can effectively prevent the occurrence of diseases.
1. Change water: To treat white spot disease, first of all, we should pay attention to changing water. The quality of water has a great impact on the health of fish. During the illness, every other day should be changed, but not too much, in order to avoid the fish have a stress response, each time can be changed about a quarter.
2. Heating up: The white spot disease is caused by the small melon insect. The survival of this parasite is affected by the temperature. Generally, it will stop growing at 25 ℃, and will die in large numbers at 28 ℃. Therefore, by heating up, the small melon insect can be well eliminated, so as to cure the white spot disease. Maintaining high temperature at ordinary times can also play a preventive role.
3. Add salt: In addition to changing the water and raising the temperature, you can also add a proper amount of salt to the fish tank, which can reduce the burden on its kidneys, and at the same time prevent some harmful bacteria from entering the fish with the water, in order to prevent any other diseases.
