November:The temperature is getting colder, the water temperature is mostly about 10, the goldfish has a normal appetite, change the water once every 20 days, pay attention to the balance of the old and new water temperature when changing the water, and try to keep the ornamental fish in the green water, and strengthen the medicine for the sick individual**.
December:Temperatures are dropping, and this month's focus is on keeping goldfish warm. The appetite of the goldfish decreases significantly, the water is changed once in about 30 days, the feeding work is delayed until around noon, the stocking density of the fish pond can be appropriately increased, the water color is mainly green, and the water level of the open-air fish pond should be appropriately deepened.
January:This month's climate is very cold, is the coldest season of the year, should do a good job of keeping the goldfish warm, if conditions can be moved to the indoor or warm house winter, to minimize the replacement of water quality, bait work concentrated at noon.
February:In late February, the temperature gradually warms up, and the feeding of goldfish is intensified. The water quality is generally changed once around 30. Select broodstock, reduce stocking density, strengthen broodstock fattening, and make preliminary preparations for the reproduction of broodstock.

As the temperature begins to rise in spring, the rate of organic matter decay in the feed water is significantly accelerated, if the southeast wind blows in a few days, the temperature rises significantly, it is necessary to replace the wintering water of ornamental fish in time to prevent goldfish from hypoxia.
Later in March, the gonads of ornamental fish have matured, and if the water temperature is raised at room temperature at this time, the goldfish will reproduce early. When the weather is fine, different species of goldfish are kept separately in a fish pond according to a certain proportion to prepare for nesting.
