After the tropical fish grows white spots, the first thing to do is to change the water. The aim is to dilute the bacteria content in the water and provide a healthier living environment. The difference between peace and time is that the water should be changed every day at this time, so that the water quality can be improved as soon as possible, but the amount of water should not be too large each time, otherwise it will stimulate the fish body.
After changing the water, all you have to do is raise the temperature. White spots are usually caused by white spot disease, which is caused by parasites such as small melon worms. As long as the temperature is raised to about 30 ℃, they will be eliminated. If it is other diseases, warming can also promote the metabolism of fish, improve its own resistance, for disease treatment is also helpful.
After the temperature is raised, the next step is to add salt, because raising the temperature has a certain negative effect, which will accelerate the reproduction speed of bacteria, and by adding salt, the osmotic pressure of the water body can be changed to reduce the infiltration of water into the fish body, so that the invasion of bacteria can be further curbed. It should be noted that the concentration of salt should not be too high, generally maintained at three thousandths.
If the condition still does not improve after changing water, warming up and adding salt, it is necessary to treat it by soaking in medicine. Commonly used fungicides are potassium permanganate or formalin, control the concentration of the solution, soak for a period of time after fishing out.
