Ornamental fish rotten tail, no matter what kind of reason, there will be rapid reproduction of bacteria, this time the water will become turbid, affecting the health of the fish. Therefore, it is necessary to change the water in time, usually every other day, between one third and one half of the water, so as to reduce the bacterial content as soon as possible and provide a safer growth environment.
After changing the water, the next step is to raise the temperature. Compared with normal cultivation, the temperature is generally raised by 1-2 deg C, and the purpose of raising the temperature is to stimulate the fish body, accelerate the metabolism and improve the resistance of the fish body, so as to better carry out self-healing. However, there is also a disadvantage of heating up, that is, the rate of bacterial reproduction is accelerated, so after heating up, there is still a very important step to be done.
Heating up has a certain side effect, that is, to accelerate bacterial reproduction, but adding salt can improve this situation. The concentration of salt is generally about three thousandths, which can not kill bacteria, but can change the osmotic pressure, which can reduce the possibility of bacteria invading fish through water, thus providing protection for it.
If changing the water, warming up and adding salt do not make the health of the fish better, then only medicated bath can be used. Select the drug according to the situation of rotten tail, take the fish out of the tank, soak it in the drug solution for about 10-20 minutes, which can kill the bacteria on the surface, and then put it back. A regular medicated bath can cure it.
