White disease is also called saprolegniasis. This is a common disease of ornamental fish. If you want to treat it, you need to change the water in time to keep the water clean and sanitary, and reduce the content of mold in the water. At the same time, you need to raise the temperature appropriately. Rising the temperature can stimulate the fish's resistance, which is conducive to its better recovery. In addition, some bactericidal drugs should be used, such as furacilin or malachite green soaking.
1. Fish body injury: The reason why fish get white disease is that the bacteria invade from its wound. Healthy fish rarely get this disease. There are many reasons for its injury, may be caused by fighting, may also encounter a sharp stone, after the discovery must be timely isolation, or take out the stone.
2. Poor water quality: The white hairs on the fish are actually the hyphae of fungi, and poor water quality is the main cause of the growth of fungi. In peacetime, we must pay attention to changing water, which can improve the water quality and avoid excessive number of harmful bacteria in the water body, resulting in fish illness.
3. The temperature is too low: It is easy to catch the white disease when the temperature is low. At this time, the fish's resistance is relatively low, and it is not easy to recover after illness. In the process of feeding, we must pay attention to temperature control, the temperature can not be too low, and the temperature difference can not change too much.
4. Insufficient light: If the light is insufficient, it is also very easy to cause the breeding of fungi. As long as you bask in the sun properly, you can effectively kill some fungi and bacteria, thereby reducing the possibility of disease.
