Whether grass goldfish should be warmed in winter is best decided according to the area where the breeder is located, because grass goldfish are cold water fish and can adapt to life in cold water. Even at 0 ℃, they can grow normally. If the breeders live in the south of our country, it is ok not to heat them in winter. Because winter in the south is generally not too cold, grass goldfish can survive normally.

If the breeder lives in the north of China, it is best for the breeder to install a heating rod to keep the water temperature constant. Because winter in the north is generally below 0 ℃, and ice may occur, it will cause them to freeze to death if they are not installed with heating rods. Of course, if the breeder can move the grass goldfish to a heated room, it is ok not to heat them.

Grass goldfish need to be fed in winter, but the feeding frequency and feeding amount should be adjusted. Because their appetite and activity will decrease in winter. If they continue to feed a large amount of food, they may suffer from indigestion. If the grass goldfish is not eating well, it is best for the breeder to feed them once every 2 days, and the amount of each feeding can be finished within 3-5 minutes. In winter, it is best to feed them some highly nutritious and digestible foods, so as to avoid indigestion and ensure their adequate nutrition.
