of ichthyosis requires changing the water in the fish tank first, raising the water temperature properly, and adding salt to the water, or using furacilin with gentamicin bath. Usually when a fish suffers from this disease, the scales will stand up, and with a little pressure, the watery liquid will be ejected from its base, and the scales will fall off. Sometimes there are even symptoms of skin bleeding and abdominal distension.
? 1. Fluctuation of water quality: Fish fry scales may be caused by fluctuation of water quality, that is, changing water too frequently. Fish farming needs to change water, but changing water too much or too frequently can also be harmful to the health of fish. The water is usually changed once a week, unless the tank is small and needs to be changed every few days. Do not change more than one third of the total amount of water each time, generally one fifth is enough.
2. Change of water temperature: As a poikilothermic animal, fish has a certain ability to adapt to temperature, but too large temperature difference will also make it uncomfortable, resulting in the situation of fried scales. Therefore, in peacetime, we must pay attention to temperature control, we can use heating rods to maintain the temperature, and maintain the water temperature above 20 degrees Celsius, which also has a good prevention and control effect on some diseases.
3. Bacterial infection: In addition to the above two reasons, bacterial infection can also lead to fish scales. At this time, what we need to do is to use drugs to kill bacteria. At the same time, we should also pay attention to changing water, so as to improve the water quality as soon as possible and reduce the number of bacteria in the water, which is also helpful to the recovery of fish.
