1, change water: Cold water fish body has white dot word, want to notice to change water above all. Unlike the usual water change, the water change is more frequent at this time, usually every other day. Only in this way can the number of parasites in the water be reduced and the water quality be improved, which is helpful to the recovery of fish.
2. Temperature rise: The white spot disease is usually caused by Ichthyophthirius multifiliis. This parasite cannot adapt to high temperature. It can inhibit growth by raising the water temperature. Usually, the disease can be controlled when the water temperature is 25 ℃, and it can be killed when the water temperature exceeds 28 ℃, thus curing the disease.
3. Salt: The treatment of white spot disease also needs to add salt to the water properly. The concentration of salt should not exceed five thousandths, and it should be maintained at about three thousandths. The reason why too much salt can not be added is that the osmotic pressure is too high and the water will be separated out, which will lead to the death of fish due to lack of water.
white spot disease? The cause of white spot disease is a parasite called Ichthyophthirius, which parasitizes the skin or gills of fish, causing mucus secretion in the affected area, thus forming white pustules. Because this disease often occurs in cold weather, if you want to prevent it, you'd better pay attention to controlling the water temperature and avoid fish injuries.
