What kind of fish are good to raise, and are they not easy to freeze to death in winter?

Koi carp and crucian carp can be fed, and the metabolism in winter is relatively slow, so it is easier to raise, and generally do not raise fish without scales on the body surface, which is easy to freeze to death in winter!!

First, we should pay attention to the stocking density of fish, generally about one meter of tank, about 10 cm of goldfish, up to 6-8; Second, according to the size and type of fish, feed appropriately to avoid excess food remaining in the fish tank and polluting the water quality; Third, we should pay attention to the frequency of water change, in winter, we must change the water once a week or so, no more than 3 10 of a tank of water each time, and we need to change the water every day in summer, and the water can not exceed 2 10. It is worth noting that when changing the water, do not inject tap water directly, and let it stand for more than one day in advance to reduce the content of bleach powder and increase the oxygen content of tap water.

It is best to place the fish tank in the living room or study, where the air circulation is good and it is easy to change the water; The fish tank should be placed firmly and away from the aisle as far as possible; According to the size of the living room, choose a fish tank reasonably, and do not enlarge the fish tank in a small room. Xu Jianmin finally told reporters that if there are conditions, it is best not to use fish tanks or aquariums to raise fish, wooden basins, tile basins, or cement pools, whether it is for the health of fish or human health, it is a better choice.

Goldfish. Carp.

Koi. Ballast on the surface of the water will not freeze to death.

Whether fish farming in winter will freeze to death depends on the type of fish on the one hand, and the temperature on the other hand. First of all, let's talk about fish, generally fish are divided into tropical fish, temperate fish and cold fish, among which tropical fish have higher requirements for water temperature, the temperature must be controlled at more than 20, and it is easy to freeze to death if it is not heated in winter. On the contrary, the cold ribbon fish is not resistant to high temperatures, and the water temperature should be below 20.

Temperate fish are broad-temperate fish, as long as the temperature is above 0, it is generally fine.

1. Goldfish: Goldfish are suitable for raising no matter what season, and winter is no exception. This fish evolved from crucian carp and has been cultivated in China for more than 1,700 years.

There are many types of it, which are usually divided into four series, namely grass species, literary species, dragon species, and egg species, each with different characteristics.

2. Koi: Koi is a high-grade ornamental fish, which is not only beautiful in appearance, but also bright in color, which is very suitable for breeding and ornamentation. This fish has a certain tolerance for low temperatures, usually to stay above 5, too low can also affect its survival.

3. Chinese betta fish: betta fish is generally divided into Thai betta fish and Chinese betta fish, Thai betta fish belongs to tropical fish, must be in warm water to live, and Chinese betta fish is different, it is widely distributed in our country, adapted to the climate of various places, so some are not very afraid of cold, suitable for breeding in winter.

Like cats and dogs, there are many people who like to raise various fish, which is more suitable for people who don't like or don't have time to pet walks. There are various fish types, appearances, and colors, and different fish polyculture is also prone to special hybrid species, which bring different surprises. However, there are also differences between tropical fish and cold-water fish, especially if you raise tropical fish, you should pay special attention to ensure their water temperature, otherwise the fish are very prone to problems.

So what kind of fish will not freeze to death in winter?

1.Goldfish Goldfish is one of the common aquarium fish. They are wide-temperature fish and adapt well to temperature changes.

There are many types of it, some of which are more delicate and should not be raised in cold water. However, the most common varieties are very hardy and can tolerate lower temperatures without fear of freezing to death.

2.Koi As an ornamental fish of the carp family, koi also has many characteristics of the carp itself, such as its strong adaptability to temperature. However, it should be noted that the growth rate of koi fish is affected by temperature, so although the low temperature does not freeze to death, the development will also be slow.

3.Trout Trout Trout, also known as mirror fish, is a small freshwater fish that can be eaten or used as an ornamental fish. Generally live in slow or still waters, have a strong adaptability to temperature, and are not too afraid of low temperatures. It is distributed in almost all water systems in our country.

In addition, there are white cloud golden silk, also known as Tang fish, as well as Chinese betta fish and medaka.

1.Just change the water every 15 to 20 days. In winter, the appetite of the fish decreases, the excrement will also decrease, and the water pollution of the entire fish tank will be slower. In addition, the rate of deterioration of water quality has slowed down at low temperatures.

2. Choose the right time to feed the fish in winter, preferably at noon, with suitable temperature conditions. The coldest times of winter are in the morning and evening, so it is best not to feed the fish during these two periods. When the weather gets colder, its appetite decreases, so feed it in moderation, don't feed the fish too much, and make sure the goldfish eats it in about 10 minutes.

If you sprinkle too much feed into the tank, the fish will not be able to eat it, and some of the remaining feed in the tank will also contaminate the tank.

3. The water temperature should not be too low in winter, at least above 4 degrees Celsius. Heating rods can be used, or the temperature can be warmed up by lighting for a few hours a day. In winter, if the temperature is not well controlled, tropical fish are prone to fish diseases.

4. The temperature in winter is not too high, and the chance of fish getting sick will be smaller. But you can't be too careless. It is not possible to not clean the fish tank for ten and a half months, but it is still necessary to remember to clean and protect it regularly. After all, fish diseases in winter are incurable.

When the fish kept in the garden tank survive the winter, the fish tank needs to be buried in the soil, and the exposed part is wrapped in clothes or quilts. It is also necessary to add salt to the fish tank to prevent the surface of the water from freezing and the fish from floating to the surface for ventilation. In addition, it is also necessary to supplement the nutrition of the fish so that the fish has enough fat to survive the winter.

In winter, fish are not frozen to death, and the keeper needs to decide how many degrees the heating rod can heat according to the minimum temperature that the fish species can adapt to. It is also necessary to feed the fish more of the foods they like to eat, and increase the feeding once a day so that the fish have enough fat to survive the winter. In winter, the frequency of water changes needs to be reduced to avoid the death of the fish due to a stress response.

In winter, fish are not frozen to death, and breeders need to keep the fish warm. Breeders need to decide how many degrees the heating rod can be heated to for the winter according to the temperature that the fish species can adapt to.

Breeders also need to nurture the fish in the winter, so that the fish accumulate enough fat to survive the winter. Breeders need to feed more of the foods that the fish like to eat, and increase the feeding once a day.

In winter, breeders need to change the water less frequently. Avoid changing the water too many times, resulting in the fish being unable to adapt to the change in water quality, and the stress reaction will weaken and the body will freeze to death.

As long as you pay attention to the temperature of fish farming in winter, the fish are generally not easy to die. It is worth mentioning that fish are ectotherms, so they are easily affected by temperature, and if there is no heating rod to control the temperature, the vitality and appetite of the fish will also decrease when the water temperature is reduced, so it is necessary to reduce feeding. At the same time, the interval of water change is also extended, and the growth of microorganisms at low temperatures is also limited, so there is no need for frequent water changes.

1. Medaka: This simple medaka refers to the medaka genus of the medaka family, its body size is not large, there are many types, and the medaka is a good ornamental fish that has been cultivated, this fish has a strong ability to adapt to temperature, so it can be fed without heating, but it is best to improve the problem during the breeding period.

2. Tang fish: Tang fish, also known as Baiyun golden silk, is an endemic fish species in China, it is basically extinct in the wild, but there are many artificial breeding. This fish is suitable for growing in weakly acidic water, has a relatively mild temperament, and has many acceptable food types, so it is easier to raise.

3. National Dou: National Dou is the abbreviation of Chinese betta fish, which is different from the common Thai betta fish, and the domestic betta fish has very good adaptability, especially in a low-temperature environment, so it is also suitable to raise in winter, and it is not easy to raise to death.
