Tips for raising cold water fish without dying, how to change the water for cold water fish?

Many have just farmed ornamental fish.

Aquarists will have this experience, no matter how careful they are, the purchased ornamental fish will always die in a short time.

Although there will be many reasons for the death of fish, and it will not be able to explain it in a while, but we can at least reduce our mortality by paying attention to the following points in the future fish selection and fish farming.

1. Novices should never go to the stall to buy fish.

The old way of fish farming said something unpleasant, the stall fish is prepared by children and the elderly, and then it is for the fish veterans to pick up the leaks.

If you are a novice who really wants to raise ornamental fish, please refuse to sell fish for the time being, although I have also set up a stall to sell fish before.

But because of this, I don't want people to buy it.

2. Don't be greedy.

This also teaches you a good way, for example, if you raised ten fish in your fish tank last time and all died, then this time we only need to raise half of them, for example, we can raise five or even less, and this is no problem.

Most of the ornamental fish of many new aquarists are due to the lack of oxygen and death of the fish due to high breeding density, or the water quality is corrupted.

3. Don't rush to add fish when the fish is dead.

If we don't get sick of fish, and the fish die in large numbers, then let them die, and don't add more fish in the middle process. But after we die, we have to soak and disinfect the fish tank with strong salt water, or simply take it to the sun and expose it to the sun for a week before raising the fish.

Sunlight and table salt are the easiest and most effective resources we can find, and we don't use potassium permanganate.

Chlorine dioxide is so laborious, and the anti-virus effect is very good.

Fourth, not only the quantity is small, but the variety is as single as possible.

Friends who have just learned to breed ornamental fish should remember to pick a family to buy fish in the west, it is easy to cross-infect, and do not learn polyculture first, it is our biggest victory to raise a species, not only do not be greedy for more quantities, but also do not be greedy for more varieties, so that it will be much simpler to raise.

Fifth, if you don't know how to raise water, you will be trapped in water.

It doesn't matter if you don't know how to raise water, many fish actually as long as they choose a good fish, even if they can't raise water for a long time, there is no problem, the water will be raised slowly, but if they don't get stuck in the water, the fish may die quickly, and the trapped water itself is also raising water.

Trapped water is actually very simple, that is, find a bucket and other water containers, must be wide-mouthed, even if there is no oxygen explosion, two on three or five days is always okay, right? Stuck in water is as simple as that, we don't need to do anything, remember to change the water every time.

It is enough to trap the water in advance and pay attention to the water temperature.

6. Don't feed for the first three days, and change the water for one-third each time.

This is the basic routine of fish farming, don't feed it for the first three days, and then you can feed ordinary fish once a day.

It is best to change the water in a quarter each time, and a third is also OK, once a week, anyway, remember one: just don't change the water completely.

Tips for raising cold-water fish, one is not to be greedy, a fish tank is generally three to five is suitable, the second is that the water should be exposed to the sun, generally about three days of sun, and the third is that the fry should be selected, whether it is a small fry or a medium fry, they must be spiritual and fresh.

My fish tank is a meter * The small side is a meter, and the middle is about a meter.

Raising cold-water fish should first pay attention to controlling the temperature, and cold-water fish also have requirements for temperature, usually not higher than 20. Usually pay attention to feeding, you can feed 1-2 times a day, do not feed too much each time. In addition, it is necessary to change the water regularly to keep the water clean and hygienic, which is very helpful for the health of the fish.

When changing the water, it is best to clean the fish tank and pump out the dirt at the bottom to prevent the deterioration of the water.

1. Control the water temperature.

The first thing to pay attention to when raising cold-water fish is the water temperature, and the requirement for cold-water fish to the water temperature is not higher than 20, otherwise it will be life-threatening. However, most of the cold-water fish mentioned at present are actually some wide-temperature fish, which have a wide range of temperature adaptation and can survive in an environment of 0-40.

2. Feed the food.

There are many types of cold-water fish, and their feeding habits are also different, so it is important to choose the right feed for feeding. Usually 1-2 times a day, if you are raising adult fish, you can feed them every other day. Don't feed too much, if there is a lot of residual bait in the water, it is easy to cause the deterioration of the water body and calmly affect the health of the fish.

3. Change the water regularly.

Cold-water fish should also be changed regularly, and the water change cycle should generally be decided according to the water quality. If the water body is not well maintained, it should be changed once every three or four days, but it is generally enough to change it once a week. If there is a filter in the tank, it can also be changed once every half a month or a month, and the water should be changed about a quarter each time.

Fourth, pay attention to cleanliness.

Fish farming must pay attention to cleanliness, not only to clean up the bait, but also to remove the fish in the tank. If there is filtration, it can be sucked out, but if it is not, it can only be sucked out when the water is changed. In addition, if there are signs of algae explosion, the algae also need to be cleaned up so as not to affect the dissolved oxygen in the water body and cause the fish to lack oxygen.

Cold-water fish is also one of the species of fish, and when the temperature is above 20 degrees Celsius, the fish will die. Let's take a look at how to farm cold-water fish.

The temperature at which the cold-water fish live is very important, the fish has high requirements for the temperature of the water, for example, the temperature is higher than 20 degrees Celsius or below 12 degrees Celsius, the fish will die, so if you want to breed cold-water fish, you first need to control the water temperature.

The fish pond for breeding cold-water fish is best rectangular, square and other structures, and the height of the fish pond can not exceed 4 meters, and the fish pond should have a good excretion capacity, so as to ensure the health of cold-water fish.

Food should be stocked mainly according to the number and size of cold-water fish, and the food should not be put too much, so as not to make the cold-water fish unable to eat these foods, so that these foods accumulate on the bottom of the water, resulting in poor water quality in the fish pond.

Cold-water fish are also susceptible to infections and diseases, so it is important to clean the pond regularly to prevent water pollution and hazards to cold-water fish.

If you want to raise cold-water fish easily, you need to keep it at the right temperature to avoid death. Because cold-water fish have strict requirements for temperature in the process of life, the temperature of the general water is best controlled at about 20, which can avoid the death of this fish, so if you want to breed cold-water fish, you must first control the water temperature.

01 Secondly, when breeding cold-water fish, if the number is relatively large, it is best to set the fish pond as a square or rectangle, and the height of the fish pond should be kept at about 4 meters. At the same time, the fish pond should have a good excretion capacity, so as to ensure the healthy growth of cold-water fish.

02 When putting food on cold-water fish, it is necessary to put it appropriately according to the size and quantity of cold-water fish, and do not put too much at one time, so as to avoid indigestion and death after eating cold-water fish.

03 Finally, when breeding cold-water fish, it is easy to cause some diseases, so it is necessary to clean the fish pond on time to avoid disease infection, resulting in cold-water fish in the process of growth.

Summary. Hello dear, raise a good cold-water fish to do the following: First, raise fish first raise water, water to raise fish will not get sick, new fish to buy when the water for a few days, in the fish farming. Second, when feeding the fish, you should feed less, do not feed too much, so as not to affect the water quality of fish feces.

Tips: The exchange is 2 rounds of replies, and you can only send 2 times what you want to say. Please describe in detail what you want to know about each time and pay attention to the number of times so that it does not fail to help you solve the problem.

Third, the density of fish farming can not be large, according to the size of the fish tank, the size of the fish to determine. Fourth, when raising fish, it is necessary to change and wash the filter cotton frequently, and the filter cotton should be scalded with hot water. Fifth, change the water every week.

When changing the water, replace two-thirds of the water in the fish tank and clean the dirt on the inner wall of the fish tank, add water to be about the same temperature as the water in the fish tank itself, add appropriate special salt for fish farming, and add salt according to the size of the fish tank. Sixth, the fish feed should be fed to enhance the physique and nutrition type, and the color type should be mixed with feeding. People should be diligent, wash the filter cotton once a day and scald it with hot water.

Seventh, it is very important to control the water temperature of the cold-water fish, the fish has high requirements for the temperature of the water, such as the temperature is higher than 20 degrees Celsius or lower than 12 degrees Celsius, the fish will die, therefore, if you want to breed cold-water fish, you first need to control the water temperature.

1. The density of the fish tank is small.

2. Use three-in-one filtration, with filtering and oxygen pumping function.

3. Guizhou rock climbing loach rubs the cylinder wall.

4. The apple snail wipes the bottom of the tank and eats the fish that has not been pumped away by the filter pump.

5. Put the sunken wood with Moss to purify the water.

6. Control the amount of feeding, the author feeds once a night, and the fish are actively grabbing food.

7. Feed better fish food, mixed carnivorous fish (map, parrot, etc.) fish food feeding, fish are not easy to get sick.

It is best to raise koi fish for cold-water fish at home.

Koi fish are gentle by nature, like to swim in groups, easy to raise, and have strong adaptability to water temperature. It can live in a water temperature environment of 5-30 and grow at a water temperature of 21-27. Koi carp and goldfish have the same requirements for water temperature and water quality, and the suitable temperature range is 2 -30, but they cannot resist the sudden change of water temperature, and the temperature difference suddenly exceeds 2 -3 Koi will be uncomfortable, and the optimal water temperature is 20 -25; It requires sufficient oxygen and is suitable for living in a slightly alkaline and low-hardness water environment.

Koi fish are omnivorous fish that can be eaten by molluscs, debris of higher aquatic plants, benthic animals, fine algae or synthetic pellet bait. It is best to feed synthetic granules, bait, bean cakes, vegetable cakes, bread crumbs, fish insects, clams, crab meat, wuxing cracked weed, duckweed, etc. It's best to feed the bait regularly.

The common carp is a very resilient fish, and the koi also retains this trait. They can be kept anywhere from small fish tanks to large outdoor ponds, and they can quickly grow to 30 cm or larger, so using a traditional indoor fish tank is not as good as a round plastic pot. Koi fish are cold-water fish, so it is best to raise koi fish in hot places in the summer to a depth of half a meter or more.

For the general stocking of the fish pond dense zone, please refer to the density table of the fish pond stocking koi; The density of the aquarium is generally 60 cm, 30 cm and 15 cm, and 6 koi carp with a body length of 15 cm to 20 cm can be stocked; 90 cm, 30 cm, 50 cm can be stocked with 8 tails; 110 cm, 30 cm, 50 cm can be stocked with 10 tails.

Koi fish are managed differently depending on the seasonal temperature.

1. In spring, the weather is warm and cold, the koi begin to recover from hibernation, and the feeding is transferred from indoor to outdoor, but special attention should be paid to sudden cooling, and the film should be covered in time to keep the water temperature stable; The bait is mainly plant-based bait, and the amount of bait gradually increases from less to facilitate the digestion and absorption of koi.

2. In summer, the weather is hot and hot, and it is necessary to cover with a plastic shading net to prevent direct sunlight, so that the illumination of the sunlight model is reduced from 8000-12000 lux to 5500-5800 lux is the most suitable.

3. In autumn, the weather is less rainy and sunny, and the water temperature has dropped significantly, which is the most suitable for the growth of koi carp, which can increase the proportion of animal sex (protein), such as silkworm pupa. Increase the amount of investment to promote fast growth.

4. In winter, the weather is relatively cold, when the temperature drops to 0, the koi carp should be transferred to the indoor fish pond in time for wintering, the indoor water temperature should be kept at 2 -10, pay attention to the focus on heat preservation, appropriate bait, fat protection and disease prevention, from November to March of the following year for the koi wintering period.
