1. Suffering from white spot disease 1. Reason: When an eyebrow mermaid is infected with white spot virus and suffers from white spot disease, their body will be covered with white spots. This situation requires them to be treated with drugs.
2. Treatment method: First, fish out the sick mermaid and put it in a feeding tank. Because the disease is contagious, it can prevent them from infecting healthy fish. Then apply potassium permanganate to their body surfaces to sterilize them. Apply 2-3 times a day, and put them back into the fish tank after they recover.
2. The water quality is too poor1. Reason: If you don't change the water in the fish tank for a long time, it will lead to a large number of bacteria in the fish tank. They can infect a mermaid, causing them to get sick.
2. Treatment method: First, pour out the water in the fish tank and sterilize the fish tank with crude salt. Then two-thirds of the poured water is poured in to avoid harm caused by excessive changes in water quality. Then add one third of the water with little difference from the original water quality to improve the water quality in the fish tank.
3. The temperature changes too much1. Reason: The mermaid is a temperature-changing animal, which can accept a large temperature range, but the sharp change of temperature will reduce their resistance and cause certain harm to them.
2. Treatment: Add a thermometer and a heating rod to the fish tank. Turn on the heating rod, stare at the thermometer, slowly raise the temperature in the fish tank, raise the temperature in the fish tank to about 25 ℃, and maintain a constant temperature.
