cold-water fish. If the tail is rotten, stop feeding it first. Generally, during the period of illness, the appetite of fish will be affected, so they will not eat anything. More importantly, too much organic matter in the water will lead to the deterioration of water quality, which will not help the recovery of fish, but will be harmful, leading to the aggravation of its illness or other diseases.
in the early stage of the fish disease, do not need to use drug treatment, but to carry out the old three. The first step of the old three is to change the water, which is different from the usual water change. At this time, the water should be changed frequently, once every other day, so as to improve the water quality, reduce the number of harmful bacteria in the water, and prevent the deterioration of the disease. The second step is to increase the temperature, not more than 2 degrees Celsius every day, until the water temperature is about 25 degrees Celsius, warming can accelerate metabolism, so that fish will discharge harmful substances. The third step is to add salt. Proper salt can prevent the bacteria from continuing to attack the fish. The concentration is usually about three thousandths.
If the condition of rotten tail is serious and can not be treated by relying on the old three, it is necessary to let the sick fish soak for treatment. Commonly used medicine is furacilin, that is, yellow powder, prepare 100 kilograms of water, pour 0.2 grams of medicine into it, then soak the fish in it, and fish it out after 10-15 minutes.
