After the fish is fried, the first thing to do is to change the water for it, because the water contains some harmful substances, by changing the water can reduce their content, improve the water quality, avoid the fish's condition continues to worsen, for its recovery can play a certain role. Usually, the water should be changed every other day, about one fifth of each time.
After changing the water, the next step is to raise the temperature. The temperature should be raised to about 32-33 ℃. The advantage of raising the temperature is to accelerate the metabolism of the fish and stimulate its immunity, so that it can better recover. However, the increase of water temperature will also lead to a large number of bacterial reproduction, while reducing dissolved oxygen, so oxygenation and salt are needed.
The purpose of salting is not to kill bacteria, but to change the osmotic pressure of the water body. Because the osmotic pressure of the freshwater fish body is higher than that of the water, water will constantly soak into the body from the outside, which will also bring in some bacteria. After salting, the osmotical pressure of water will increase, reducing the entry of water, which has a certain effect on preventing bacteria.
It is still necessary to use drugs for treatment after scaling. Mix 1% salt water with 1% baking soda and soak the fish for 10 minutes. Furacilin can also be used to sprinkle the whole cylinder, but the dosage must be strictly controlled. In addition, you can also choose penicillin, gentamicin and other immersion.
