The methods for goldfish to prevent white spot disease mainly include the following points:
Maintain Clean Water Quality: Regularly change the water in the fish tank to ensure the water is clear and odor - free. You can use water quality testing tools to detect indicators such as ammonia nitrogen and nitrite in the water to ensure water safety. When changing the water, it is best to expose the water to the sun or let it stand for 2 days before use to remove harmful substances like chlorine.
Control Water Temperature Changes: Goldfish are very sensitive to water temperature changes. Excessive temperature differences can easily cause stress reactions, leading to the occurrence of white spot disease. Therefore, maintaining the stability of water temperature is crucial. You can use a thermometer to monitor water temperature changes in real - time, ensuring that the water temperature remains within an appropriate range, usually above 25°C.
Maintain a Reasonable Stocking Density: Avoid overcrowding, keep a reasonable stocking density, and reduce the chance of disease transmission. If there are diseased fish in the fish tank, immediately isolate them from healthy goldfish to prevent the spread of the disease.
Use Disinfectants: When introducing new fish, disinfect the fish with potassium permanganate solution or salt water, which can effectively prevent the occurrence of white spot disease.
Regularly Disinfect the Fish Tank: Disinfect the fish tank with salt and medicine to kill possible parasites and germs.
Through the above measures, the occurrence of white spot disease in goldfish can be effectively prevented, ensuring the health of goldfish.
