What do you need to pay attention to when raising fish in winter and how can you raise it well

Four points should be paid attention to when raising fish in winter. The first is to change water. Because the water temperature decreases, it is not necessary to change water too frequently. Usually, it can be changed once every 15-20 days. Secondly, we should pay attention to feeding, reduce the appetite appropriately, and usually choose to feed at noon. If the temperature is too low, pay attention to heat preservation, especially if tropical fish are raised, the water temperature should not be lower than 20 ℃. In addition, we should do a good job in disease prevention.

1. Change water

As the temperature drops in winter, fish's activities will decrease and their appetite will not be very good. In this period, if they eat less, they will excrete less. At the same time, low temperature will curb the deterioration of water body, so it is not necessary to change water too frequently. Usually, after October, it can be changed every 15-20 days, and in December, it can be changed every 30 days.

2. Feeding

As mentioned above, the appetite of fish will also decrease after cold weather, and feeding food can be reduced at this time. Usually, it is fed once every 7-10 days. Don't put too much in it every time. If you put too much in it, it won't eat it, which may lead to the deterioration of the water body. Feeding time is usually at noon, and it is easier to eat when the climate is warm.

3. Heat preservation

If wide-temperature fish, such as goldfish and koi fish, are raised, their temperature requirements are not very high, but the water temperature should not be lower than 0 ℃, and it is best to keep it above 4 ℃. If it is a tropical fish, it should be heated with a heating rod, and the water temperature should be controlled above 20 ℃, otherwise the fish will die.

IV. Disease prevention

The temperature in winter is low, and the reproduction of germs is usually limited, so it is not easy to get sick, but once you get sick, it is difficult to recover, because the low temperature leads to the decrease of its metabolism and the harmful substances in the body are not easy to be discharged. Therefore, we must pay attention to disease prevention and clean up regularly.
