White spots on the fins of map fish are caused by white spot disease, which can be corrected by increasing the water temperature or red water.
Methods to control white spot disease:
1. Use the method that the white spot insect is not resistant to high temperatures, increase the water temperature to 30 degrees, and urge the spores produced on the surface of the fish to mature as soon as possible , speed up their growth rate, make them fall off the surface of the fish body, and then change the water.
2. Reduce water adjustment. The key to this method is not to add too much. The water color should be slightly red. It is better to use less than too much. Soak for 5-10 minutes, 1-2 times a day.
Be careful not to use mercury nitrate or malachite green. These two drugs are highly toxic products that can cause great harm to the human body and can easily lead to cancer.
Fish with white spot disease are covered with white spots. Each white spot cyst contains many juvenile white spot insects. The white spot insects absorb nutrients from the fish body structure and grow up and reduce in number. Later, it breaks out of the capsule, swims into the water, and then returns to the fish body to erode the skin and produce more small white spots.
In the early stages of white spot disease in map fish, the sick fish will rub their bodies against hard objects in the hope of getting rid of the unpleasant disease body. There are many small white spots on the body surface, fins and gills of the sick fish. The sick fish are weak, floating on the water surface or gathered in a corner, and rarely move. In the later stage, the body surface seems to be covered with a white film, the mucus increases, and the body color is dim. White spot disease has obvious seasonal characteristics, and the water temperature of 15-20℃ is most suitable for the growth of white spot disease.
When raising map fish, owners must pay attention to the health of the water quality.
