Causes of white spots rotting on parrot fish
1. Caused by white spot disease: White spots and decay will appear on the surface of parrot fish. The most common reason is that it suffers from white spot disease. This disease is mainly caused by the proliferation and invasion of small melon bugs. It is usually caused by the low temperature of the water in which the parrot fish is raised, because the small melon insects only grow and reproduce in a low temperature environment (below 25°C).
2. Caused by skin mildew: White spots on the parrot fish may also cause it to suffer from skin mildew (Saprolegnia). This disease is mainly caused by the fact that the water in which the parrot fish is raised has not been changed for a long time. Water quality changes or bacteria invade the surface wound of parrot fish. However, because of the appearance of white spots and white flocs in the early stage of skin mildew, many people directly think that it is white spot disease. Therefore, the breeder should carefully observe the cause when the parrot fish is sick.
What should I do if the parrot fish has white spots and rots?
If the white spot disease causes white spots to rot on the parrot fish, the owner should immediately increase the water temperature of the fish tank
to 30°C, and then replace the water in the tank. At the same time, sprinkle an appropriate amount of fish-specific salt to disinfect and treat parrot fish. If the parrot fish is seriously ill with white spot disease, the owner needs to use a 3% concentration of malachite green or methylene blue solution for treatment, and isolate the sick fish to avoid infecting other healthy parrot fish. .
If the parrot fish is suffering from skin mildew, the owner needs to soak the diseased parrot fish in 3% salt water (about 10 minutes), and the parrot fish will die in about a week. will be fine. If the symptoms of skin mildew are very serious and the parrot fish has no appetite, the feed is mainly treated with potassium permanganate solution or nitrofurazone solution for medicated bath treatment, and an appropriate amount of potassium permanganate solution can also be applied to the rotten position for disinfection. At the same time, during the treatment of sick fish, the water in the fish tank should be changed every three days to prevent the parrot fish from aggravating the disease due to unclean water quality.
