How do goldfish survive the winter, and how do domestic goldfish survive the winter?

First of all, the fish tank should be placed in a well-lit place indoors, and the room temperature should be kept above 4 degrees Celsius, so that the goldfish have a certain appetite. Although goldfish have a strong ability to adapt to water temperature, too low water temperature will cause the goldfish to lose their feeding rate, emaciation, slow activity, and dull color. If the room temperature is too low, you can consider increasing the temperature appropriately, and you can also use a light bulb to increase the light to maintain the goldfish's body color.

Secondly, cast less bait and cast sperm bait. Every 2 to 4 days, bait is cast at noon. If it coincides with the water change, the bait is given after the water change. The amount of bait is subject to half an hour, and increases or decreases with the temperature. Hibernating goldfish do not need to be fed.

In addition, it is also more important to change the water in winter. The water change cycle is from 1 week to half a month, and it should be carried out at noon. One-third of the water is replaced, and only fish feces and dirt from the bottom of the tank need to be pumped out, and then new water is injected, and the water temperature is 2 to 3 degrees Celsius higher than that of the original tank.

If the water is not dried or the temperature is lower than the original tank, it will cause the goldfish to catch a cold and even develop other fish diseases.

Finally, it is better not to change tanks for keeping goldfish in winter. If you really need to change the tank, the water in the new tank should be dried for a week, the new water should be 2 to 3 degrees Celsius warmer than the original tank when putting in the fish, do not use a net when fishing for fish, use a container three or four times larger than the goldfish to scoop up the fish with water, and put it into the new water together, so as not to hurt the scales. Do not feed the goldfish for 3 days when they are in the new water, so that the goldfish can better adapt to the new environment.

It's cold winter again, and how to make goldfish survive the winter safely has become a problem that breeders need to consider. Generally speaking, goldfish farming only needs to remember the following simple things.

If you don't have old water at home before buying fish, you need to use water that has been trapped for 7 days (i.e., tap water that has been in other utensils for more than 7 days) to raise goldfish.

In addition to eating artificial bait, goldfish prefer to eat bloodworms, earthworms, small shrimp, egg yolks, etc., to ensure that the bait is fresh, and the spoiled ones cannot be fed; Goldfish is a cold-blooded animal, so it is not afraid of cold, it can adapt to room temperature in general, as long as the water does not freeze it is fine, but try to keep the water temperature constant, hot and cold will definitely make the fish cold; Goldfish can be fed 1 time a day, to be fed at a fixed time, goldfish are more gluttonous, so each time you feed eighty percent full; If there is no filter, it is necessary to suck out the fish feces on time every day, and then add the same amount of trapped water as the suction (it takes 3 days), so that only a small amount of water can be changed, and the water can be kept clean and oxygen injected. More than a week (or see the water mixed) do a large amount of water change, i.e. 1 3 water changes are fine.

Place the trapped water next to the fish tank a few hours before the water change to ensure that the new water to be replaced is kept at the same temperature as the water in the fish tank, so that the fish will not be irritated.

Room temperature or when the water temperature of the aquarium is not very high (10° or below): change the water once a week or so, each time the water is changed no more than 1 3 of the old water, and feed the bait once every two days or so. Do not stop the oxygenation system, properly ventilate and maintain a certain amount of light.

Below 5°C, it should be treated against cold. (Personal experience, for reference only).

Home-raised goldfish are best moved indoors during the winter. Although goldfish can accept lower water temperatures, most parts of our country will still freeze outdoors in winter, and after moving indoors, you can ensure that the water in which the fish live does not freeze. If it is a heated room, the breeder does not need to install a heating rod.

If it is an unheated room, it is recommended to install a heating rod so that they can also grow and develop in winter. <

Home-raised goldfish need to be moved indoors after entering the winter, although goldfish do not have high water temperature requirements and can accept lower water temperatures. However, in most parts of the country, it freezes outdoors when it enters winter, so it is better to move indoors for the winter.

If there is heating in the room where the goldfish are raised, there is no need to install a heating rod. Because the indoor temperature of a heated room is generally above 20, goldfish can survive well in this temperature range. If it is an unheated room, you can install a heating rod.

This allows them to develop normally during the winter months.

In addition to the water temperature, the frequency of water changes should also be noted. In winter, the metabolism of goldfish decreases, and keepers need to change the water less frequently. If you install a heating rod, you can change the water every 3-5 days.

If you don't have a heating rod installed, you can change the water every 7-15 days.

Whether to feed goldfish in winter depends on the water temperature they live in to decide, if they live in the water temperature above 18, the keeper needs to feed them normally. Because the water temperature suitable for goldfish is 18-24, they can eat and move normally in this temperature range.

If the water temperature of the goldfish is below 15, it is recommended to reduce feeding. If the goldfish is not actively eating, it can also stop feeding. Because goldfish will also have a reduced appetite and activity in a cold environment, the keeper does not need to feed it anymore.

Goldfish are less active and eating and are semi-dormant, but still need to be fed.

Goldfish should pay attention to the following points during the winter:

The fish tank should be placed in a well-lit place indoors, and the room temperature should be kept above 4 degrees Celsius, so that the goldfish have a certain appetite. Maintain fresh water quality and change water sparingly. The water change cycle is from 1 week to half a month, and it should be carried out at noon.

To change the water, simply remove the fish manure and reed filth from the bottom of the tank and then inject new water. Cast less bait, cast sperm bait. Every 2 to 4 days, cast the bait once at noon.

If it coincides with the water change, the bait is given after the water change. The bait is better to use live earthworms, dried earthworms or synthetic bait, and the amount of bait is subject to eating within half an hour, and increases or decreases with the temperature. Hibernating fish do not need to be fed, as long as the management is strengthened, the goldfish can safely overwinter.

If fish are raised in ponds, the dirt and moss in the fish ponds should be thoroughly washed off before wintering to prevent the production of hydrogen sulfide from damaging the water quality. If the water needs to be changed, it should be pre-settled for a few days before use. Fish ponds with a leeward and sunny water depth of about 40 cm can be wintered in the open air without changing the water throughout the winter.
