in outdoor fish ponds? The lowest water temperature that goldfish can survive is 0 ℃. When the water temperature is lower than this temperature, goldfish will be frozen to death. So to see whether goldfish can spend the winter in outdoor fish ponds, it depends on the area where their fish ponds are located, and whether the water temperature will drop to 0 C in winter. For example, in the north, the temperature is relatively low in winter, so unless it is a deep pool, goldfish will be frozen to death, even if it is not frozen to death, the health of goldfish will be seriously affected, and the color of the body surface will gradually lose luster.
If the water temperature can ensure that goldfish can spend the winter outdoors, then adjust the feeding of goldfish according to the specific water temperature. Generally, when the water temperature is less than 15 ℃, the metabolism of goldfish will begin to slow down. If the water temperature drops to 8 ℃, the goldfish will become inactive and refuse to eat, and the metabolism will be extremely slow. At this time, it is necessary to reduce the amount of feed for goldfish, and increase the feeding interval, usually once a week or so. The amount of feeding each time can not be too much, feeding too much will not only make the goldfish eat too much, but also easily make the water quality in the fish pond worse.
