1. Reason: In the case of sudden temperature changes, fish are very easy to catch a cold. It may be that when changing water, the temperature difference between the new water and the old water is too much. Aft that new water is adde, the temperature of the water environment is reduced. Fish can not adapt to the new environment, immunity decline, leading to fish body cold. At this time, the disease and insect invasion of fish, it got white spot disease.
2. The treatment method is to raise the temperature. Generally speaking, white spot disease caused by sudden change of water temperature is not too serious. Heater bars can be used to raise the ambient temperature for treatment. In that first stage, the temperature was raise to 25. degree. C. After about half a day, the fish had adapted to the temperature and heated up to 28 degrees Celsius. Similarly, after the fish adapt, they are heated to 30 degrees Celsius. After a period of time, the white spots will slowly disappear. Wait for it to heal, then return the temperature to room temperature.
1. Why: Parasites such as Ichthyophthirius have invaded the skin or gills of fish, causing white spot disease.
2. Treatment: When the fish is found to have white spot disease, should immediately stop feeding. The sick fish were isolated and then bathed with 0.3% salt water. Aft 3 to 5 days, that concentration of the saline solution is increase to 0.5%, and the medicated bath is continued for 1 to 2 weeks. If there is still no improvement, medication should be used. After the old water in the fish tank is sprinkled, mercurous nitrate or malachite is added to bathe it with medicine.
