You can raise. The situation you said was caused by the temperature being too low.
Goldfish have little appetite in cold weather.
And I don't like sports, similar to "hibernation".
This is very normal! Nothing.
The poop they pass is caused by the lack of food supplements.
This is also normal, excreting waste products from the body and then wintering is good for the body of the fish.
The crooked body is also due to a slight loss of swim bladder caused by low temperature.
This is generally slight until the temperature rises.
Hehe. My personal opinion.

Goldfish are generally not very afraid of cold, but pay special attention when changing the water, goldfish have adapted to the temperature and environment, in winter it is best to use a pipe to pump the dirty things in the ground into the tap water that has been dried at least one day in advance, and try to change the water for the fish in winter, do not keep feeding things (you can reduce the garbage in the fish tank) Take good care of it will not be a problem!
-
Goldfish do not need to use a heating rod. In the winter, you can just put the fish tank indoors, and put it in the bedroom if you can. In winter, goldfish huddle together on their own. Then try to use old water to raise fish in winter.

Goldfish are cold-water fish. It's okay to know that water doesn't just freeze.
-
If it's too cold at home, you can't raise fish.
-
I think winter words.
Try to let the fish bask in the sun.

Generally, there are heating rods in places where fish are sold, and that one can keep the water warm.
Goldfish are generally better kept in a warm room in winter, because they are different from tropical fish, so they don't need a heater much, but if you have the conditions, it is better to get one, so that the fish grows quickly and beautifully
If possible, it is better to get a low-power filter.
Make sure the water quality, otherwise you will get sick, but your tank is very small, you must have a small power, or simply make a larger tank.
I've raised 11 of them before, and the filter heater has them, and it takes 1 year to grow from 5 cm to 12 cm Super beautiful!

Goldfish can easily die in winter. I think.
My little gold died of rot last winter.

The small goldfish raised at home will freeze to death in winter, although the goldfish is very cold-tolerant and has a strong adaptability to water temperature changes, but the temperature is below 5, it will cause the goldfish to freeze to death, and when the temperature drops too quickly in winter, the temperature change exceeds 5 will also cause the goldfish to freeze to death. Goldfish will freeze to death in winter, although goldfish are ectotherms, they are very cold-tolerant, and their adaptability to water temperature changes is stronger than that of nuclear clearing. However, in winter, when the temperature is below 5, the skin deficiency will cause the goldfish to freeze to death.
Although goldfish are more resilient to changes in water temperature, they cannot accept temperature changes of more than 5 in a short period of time. If the temperature drops extremely quickly and the temperature difference is large in winter, the goldfish will freeze to death.
Keepers are advised to keep their goldfish warm in winter. Keepers need to control the temperature at 20 28, this water temperature, goldfish grow and develop most vigorously, and the amount of food will also increase.

As long as it is kept above 5 degrees, goldfish will not freeze to death. Goldfish are ectotherms, adaptable to water temperature, body temperature changes with water temperature, and can survive in water temperatures ranging from 0-39 degrees Celsius. However, goldfish cannot adapt to the drastic changes in water temperature, and the temperature rises or drops sharply by more than 5 degrees Celsius, which may endanger the survival of goldfish.
The optimal temperature for the growth of goldfish is 20-28 degrees Celsius, at this water temperature, the growth and development of goldfish is the most vigorous, the amount of food, excretion and oxygen consumption are the largest, at this time goldfish is the most vivid and lively. When winter comes, pay attention to moving the goldfish indoors to ensure that the water temperature is above 5 degrees Celsius. Goldfish has strong adaptability to water quality, has a certain ability to tolerate dirty water, and is also relatively resistant to acid and alkali, and can survive in water quality with pH value.

Goldfish is a very variable temperature fish with strong adaptability to water temperature, as long as the water temperature is not lower than 0 in winter, goldfish will not be frozen to death. Although goldfish are able to survive in cooler water temperatures, goldfish are more likely to get sick and do not grow well when the water temperature is lower. And if the water temperature is below 0 in winter, it may freeze, and freezing may cause goldfish to die of lack of oxygen.
Goldfish are ectothermic fish, and they are very adaptable to water temperature. In winter, as long as the water temperature is not lower than 0, goldfish will basically not freeze to death. For goldfish, it is not terrible to have a low water temperature, but the most feared thing is that the water temperature will change greatly in a short period of time, which can easily cause the death of goldfish.
Although in winter, as long as the water temperature is not lower than 0, goldfish will basically not be frozen to death, but when the water temperature is low in winter, it is still artificially heated. Because after all, we raise goldfish not only to pursue goldfish not to die, but also to raise them well, so that goldfish are more ornamental, and goldfish have a longer lifespan, which is what we are pursuing.
The optimal water temperature for goldfish is 22-24, when the water temperature is stable in this range, goldfish are the least likely to get sick and grow the best. When using the heating rod, it is necessary to pay attention not to place it upright in the static waters, so as not to burn the goldfish and cause unnecessary damage to the goldfish. It is also necessary to check whether the heating rod is damaged from time to time, and replace it in time if there is a problem, so as not to reduce the water temperature too quickly without heating and affect the growth of goldfish.

Whether goldfish will freeze to death in winter depends on the temperature of the environment in which they live, and if the keeper can move the goldfish indoors in winter, they will generally not freeze to death. Because they can adapt to a wide range of temperatures, as long as the water temperature is above 0, they can grow normally. But if it is an outdoor goldfish, it is possible to freeze to death.
Because the temperature in our country can reach below 0 in winter, if you do not take insulation measures, it is easy to die. <
Whether the goldfish will freeze to death in winter depends on the temperature of the feeding, if in the winter, the keeper can move the goldfish to a warm room, then they will not freeze to death in winter. Because goldfish are thermomorphic animals, as long as the water temperature is not lower than 0, they can survive normally. If it is an outdoor goldfish, there is a high chance that it will freeze to death.
Because of the cooler winter temperatures, temperatures below 0 are common. If the keeper does not increase the measures to keep them warm, then they will die.
1. Install a heating rod: If the keeper wants to make the goldfish live more comfortably, he should install a heating rod for them and keep the temperature between 22-24. In this temperature range, they live in the best state and grow the fastest.
2. Wrap insulation cotton: If the breeder is unable to install the heating rod, you can also wrap a layer of insulation cotton around the fish tank. This can also ensure that their water temperature is more stable, and even if the temperature is low, the fish tank inside the insulation cotton will not be affected too much.
3. Move indoors: If goldfish are farmed outdoors, it is best to move them indoors in winter. Because the indoor temperature does not change much, the water temperature does not fluctuate too much.
If there are few fish, use a small fish tank.
1.Soil selection.
Goldenrod is less soil-intensive, but grows more luxuriant when planted in loose, breathable, well-drained acidic sandy loam soils. Ferrous sulfate can be added to the soil every half month to keep the soil acidic. >>>More
Goldfish are not afraid of freezing, as long as the water does not freeze, the surface of the water is frozen, it is okay, feed less, and if you find that the fish is sick, you should quickly isolate it to prevent infection, and if the goldfish is sick, other fish will bite the sick fish.
First of all, it is necessary to choose a fish tank of the right size, generally in a rectangular glass tank with a length of 60 cm, a width of 30 cm, and a height of 40 cm, and it is best not to stock more than 4 pairs of small goldfish of about 6 cm. In large round fish tanks, it is best to stock no more than 2 pairs of small goldfish about 6 cm, or no more than 3 pairs of small goldfish 3 4 cm long. >>>More
It's easy to raise, my goldfish have been raised for 3 years. If you see a goldfish with its head out of the water to breathe, change the water, and don't go to catch a goldfish to avoid hurting it. It's easier to keep goldfish when you buy them big.
