suddenly in winter? In winter, the temperature in our country is generally low, although the hot goldfish is more cold-resistant, which is relative to other fish. Winter temperatures in the north are often below zero, which is totally beyond the tolerance of goldfish. The most suitable temperature for goldfish is 16-28 ℃, and it can survive at 10 ℃, but it is easy to freeze to death below 10 ℃, especially in frozen water.
Goldfish also have a greater response to temperature differences. If you live in cold water for a long time and suddenly move it to a temperature above 20 degrees, it may be stimulated and die. The frequency of changing water in winter does not need to be too high, because goldfish are generally inactive in winter, eat less and pull less, water quality is not easy to deteriorate, about once a week.
in winter? When feeding goldfish in winter, the first consideration is the temperature. It's better to move the goldfish indoors. So you don't have to worry about the goldfish freezing to death. If the space is limited, to do a good job of insulation measures, you can cover the insulation film, or open the heating rod. Although the number of water changes in winter does not need to be too frequent, in order to ensure water quality, it is also necessary to change water regularly. Change water to choose good water, if the temperature is relatively low, you can use boiling water to blend, so that the new water and the temperature of the water in the cylinder are consistent before replacement.
