in winter. Unlike tropical fish, goldfish are not as strict about water temperature. Their adaptability to water temperature is very strong, and they can survive tenaciously within 0-39 C. Generally speaking, raising goldfish in winter can make goldfish grow normally by controlling the water temperature between 14-18 C. At this temperature, goldfish can still feed normally. When the water temperature is less than 8 C, the activity of goldfish will be greatly reduced, and the appetite will also be reduced. At this time, the feeding interval can be reduced or extended appropriately.
As people's fish farming conditions are getting better and better, many people's fish tanks can be made to basically keep the temperature unchanged throughout the year, so it is OK to feed normally regardless of the season. If there is no way to maintain the temperature of the goldfish's living water, it is necessary to adjust the feeding time according to the change of temperature. In winter, when the temperature gradually drops and the water temperature drops to 8 degrees Celsius, goldfish are reluctant to move and eat. At this time, it is necessary to adjust the amount or time of feeding to adapt to the current situation of goldfish. Generally, when the water temperature is relatively low in winter, food can be fed every 7 days or so.
