Although goldfish can survive in the water temperature range of 0-39 C, this does not mean that goldfish can survive healthily when the water temperature is low. When the water temperature drops to 15 ℃, the activity of the goldfish will be affected. When the water temperature drops to 8 ℃, the appetite of the goldfish will be seriously reduced, and the goldfish will refuse to eat, and the body of the goldfish will gradually lose luster and color. If the water temperature is below 0 ℃, there will be a risk of freezing to death, so it is necessary to keep the goldfish warm in winter. As for whether goldfish can spend the winter outdoors, it depends on the local temperature, whether it will be below 0 degrees Celsius, so that goldfish may freeze to death.
in winter, the activity of goldfish is weakened, the appetite is reduced, the metabolism is slowed down, the oxygen consumption in the fish tank is slowed down, and the waste produced will be reduced, so the period of water quality deterioration will be prolonged. Because there is a risk of damaging goldfish every time you change water, you can extend the time of changing water in winter, almost once a month.
is the same, because of the decrease of water temperature, goldfish appetite decreases, so when feeding goldfish in winter, it is necessary to feed less feed, and the feeding time can be extended to 7-10 days.
