Questions about koi buy more than 20 new koi fish,

Koi chasing and biting another is generally because the chased second face is covered with germs. It is very important to transfer the water before the new fish enters the water, and the koi carp suddenly changes greatly after adapting to a water quality, which is prone to some antibody imbalances, resulting in discomfort and illness in the fish. There will be both harmful and beneficial bacteria in the water, and when the fish adapts to the water body, a balance can be achieved through antibodies, and if you turn the water badly, you will destroy this balance.

In addition, the density of koi fish is also required, such as how big the tank, how big the filtration, how big the fish should be reasonably configured, when your density is too high and the filtration is not strong, the quality of the water will be very poor and easy to make the fish sick.

You should go to supplement the basic knowledge of koi breeding, you can go to the Weibo of "Thousand Scales", where there are a series of very detailed posts such as koi breeding introduction, koi breeding advanced, and** and Mao After reading it, you can understand the questions you asked today.

Koi Top: This** can help you, you can ask questions on it and take pictures of the fish**, many aquarists will help you solve the problem, I am also one of them, I only joined a few months ago, and now I have been affirmed to enter the **group.

It is best to raise it in a pool. Raised in a tank, the filtration must be super powerful. Change the water frequently.

Change every 3 to 5 days. (in small amounts) because they eat and drink a lot of Lazar. Fish can also pee.

So keep the water fresh. Only frequent water changes. Otherwise, you will get sick Koi fish are omnivorous fish, animal or plant bait can be fed, such as daphnia, earthworms, shrimp, corn flour, biscuit crumbles, instant noodles, vegetables, and even rice balls.

However, in order to make the koi carp colorful, in addition to matching the light, background and water quality, it is more important to feed the high-nutrient special koi to enhance the color of artificial feed, there are flakes or granules, if you feed too much, you will have food accumulation or constipation and other diseases. Therefore, it is necessary to pay attention to the number and frequency of bait, and take the principle of eating less and more often, no residual bait and bad water.

If the koi can't be processed in time, some of the fish will dissolve in the water, which will increase the ammonia content in the water and make the water easy to become turbid. Fish live in ammonia-poisoned water for a long time, and their physique will gradually become weak, and they will be easily attacked by viruses in the water. Therefore, the key to raising a good fish is filtration, and filtration is mainly to filter fish feces, the toxins in the water are produced by fish feces, and only by removing the ammonia of fish feces, the water will remain clear and the fish can be healthy and less sick.

1. The suitable water temperature of koi is 5 30, and the optimal temperature is 21 27, but it is not strong to adapt to the rapid change of water temperature. If the temperature rises or drops by more than 3, the fish will get sick; After 10, the fish will die.

2. Koi fish grow slowly in strong sunlight, so it is necessary to create a shaded environment for it, such as building a shaded pergola at the corner of the pond or feeding place.

3. Koi fish live in water and rely on their gills to absorb dissolved oxygen, send oxygen to the fish body and combine with the absorbed food nutrients to produce energy to maintain life. Therefore, whether there is sufficient oxygen in the water is the key to raising good fish, and the stocking density should be thinner.

4. Koi fish are omnivorous, and generally molluscs, aquatic plants, benthic animals and small algae are the food of koi. In summer, koi fish feed more, and in winter, they eat less or almost nothing. Therefore, feeding can be increased or decreased depending on the season.

In spring, when the water temperature is above 12, bait can be put three times a day; When the water temperature drops below 12, feeding only once a day is sufficient.

5. Koi fish is an oviparous animal, the male is mature at the 2nd instar and the female is mature at the 3rd instar, and the spawning period is generally in April and June every year. At this time, sexually mature females, at 4 to 10 o'clock in the morning, the eggs are sticky, about a millimeter in diameter, white or yellowish, in vitro fertilization, fertilized eggs are best picked up and hatched separately. Generally, after 4 to 5 days of hatching, the larvae will break out of the shell.

Newly hatched larvae can be fed rotifers and clichlets, as well as crushed egg yolks.

6. Koi carp is suitable for water with weak alkaline and low hardness pH value. If the water hardness is high, there will often be a little congestion on the body surface.

There is a process of adaptation when a new fish moves from one environment to another. What koi fish are most afraid of is the sudden change in the environment, so new fish will generally have varying degrees of discomfort. Such as water quality, light, feeding, etc. So how to feed the newly purchased koi?

There is a problem of adaptation and time, the average new fish will adapt after three or four days of returning, while some fish may only be able to survive for a week or even longer, while others may have no problem at all in one day. Therefore, if you put it together with time, you still have to observe the reaction of the koi fish to see the degree of adaptation. If you want to be on the safe side, you can also don't feed the koi for three or four days like most aquarists, knowing that it's almost okay if you don't feed the koi for half a month.

When feeding, you can try to feed, you can feed a little first to see if they eat, if they still don't move much and don't take the initiative to eat, that is, they have not adapted to the environment, at this time it is still necessary to rest and then observe. If you don't eat for more than a week, you may have koi fish disease or a very poor state, at this time it is recommended to isolate it for feeding, if the fish disease is carried out immediately**, if it is a state problem, you should also choose oxygen explosion to adjust.

So is there a process for feeding the newly purchased koi, such as the amount? Of course, the new koi still has to gradually increase the amount of feeding, if it is mixed with the previous koi, then there is no need to worry about this problem, if it can really grab a lot of fish food, that is a good thing, at this time you don't have to worry about its state at all.

Newly purchased koi fish should be fed according to its state, do not feed without adapting to the new environment, and gradually increase the amount of koi fish food after slowly adapting.

How to raise the newly bought koi fish.

1. Nourish water. Water is the environment in which koi fish live, just like the relationship between people and air. To raise koi fish, you must first learn to raise water.

2. Buy koi fish.

It is also very important to buy koi fish, just like if you want to buy a thing, of course, you have to buy the best psychological comfort, so what kind of koi fish is suitable for buying?

There are three major points you should pay attention to when buying koi.

The article did not mention the most important fourth point, that is, quality, speaking of quality, one depends on the size of the koi fish, whether it is strong and upright, the second is to see the color, whether the color is pure, thick and uniform, and the third is to see the state of the koi fish, whether there is any trauma, whether it is lively and swimming.

3. Koi rearing.

The koi fish are your own, and the life of the koi is completely in your hands, so the raising of koi fish is the most arduous and long-term responsibility. If you are responsible, you have to take a good look.

How should koi fish be raised, and pay attention to preparing to raise koi fish.

1 Choose the water quality that is suitable for koi.

In general, tap water is the most commonly used water body in koi farming, and few people raise koi fish in river water, well water, and spring water. However, no matter what kind of water quality it is, it contains a certain amount of chlorine. Therefore, chlorine removal should be carried out before use. There are generally two ways to do this:

The first chemical chlorination method: an appropriate amount of sodium thiosulfide is put into water and reacts with chlorine to produce harmless sodium salt. The second physical dechlorination method: expose the water to the sun for two or three days, or continuously aerate the water to "drive away" the chlorine

2 Comply with water quality objectives.

The water in which fish are raised must be colorless, transparent, and free of turbidity; In terms of temperature, it is best to be 22 28, and try to avoid sudden changes in water temperature, which should not exceed 2, otherwise it will directly endanger the health of koi; When the normal dissolved oxygen content reaches 5 7mg l, it is more in line with the conditions of koi fish breeding; Koi fish are suitable for growing in weak alkaline water, so the alkalinity is normal at about 6. The ammonia and nitrogen content in the water body shall not exceed, otherwise it will threaten the health of the koi, and chemicals such as ammonia nitrogen are harmful to aquatic organisms, and excessive content will directly lead to the death of koi.

3 .Bait and feeding.

In the selection of bait, it is generally divided into natural bait (live bait: bloodworms, earthworms, breadworms, etc.), artificial bait (breeding material, germ family and color material, etc.). It is best to follow the "four principles" when feeding: timing, fixed, qualitative, quantitative, and develop good eating habits.

4 .Feeding management.

1 Reasonable feeding density: as shown in the figure above. Try not to exceed the water load and cause environmental stress to the koi.

2. Daily management of koi: pay attention to koi feeding, observe koi activities, adjust and test water quality. Pay attention to the breeding and management of koi fish.

I raise koi fish. Tell you a few precautions, do these things well, your fish will definitely be lively:

1. The stocking density should be small, that is, try to put as few fish as possible in the tank.

2. The water for fish farming must be dried or trapped before entering the tank. It is very important to expose to the sun for one day, or to dry it for three days, in order to remove chlorine.

3. Pay attention to the water temperature difference when changing the water, the water temperature difference is more than 2 degrees, and the koi carp can adapt to 5-30 degrees Celsius, but can not adapt to the sudden change of water temperature.

4. The best thing to raise in the tank is the bare tank, that is, the water plants, sand, stones and the like cannot be placed in the tank.

5. Koi fish eat a lot of food and excrement, so there must be filtration equipment and oxygenation equipment.

6. Depending on the water quality, the water is generally changed once every 3 days, and one-third of the water is changed each time.

The above is my experience in fish farming, which is definitely worth referencing.

When raising koi fish, you need to prepare a suitable living environment for it, and you also need to feed the koi fish regularly.

First, the selection and configuration of the aquarium:

It is necessary to choose different specifications of aquariums according to family conditions, koi fish are large in size, and the amount of activity is also large, and the general water capacity is not less than 60 kg. For larger koi fish, the water capacity of the aquarium should not be less than 200 kg. Due to the strong oxygen consumption of koi, the aquarium should be equipped with a water filter and an aeration pump to ensure that there is sufficient oxygen in the water and the water quality is clean.

Large aquariums or aquariums with a large number of koi fish can be supplied with air compressors or air pumps with high power and large output; Small and medium-sized aquariums or small number of koi fish can be used to use a special electric micro air compression pump to supply air. In addition, there should be enough lighting in the aquarium.

2. Bait and feeding method:

Koi fish is an omnivorous fish, whether animal or plant bait can be used as koi bait, such as daphnia, earthworm, rice, pasta, etc. However, it is better to choose a synthetic bait for ornamental fish. Special attention should be paid to the amount of feeding should not be too large when feeding bait in the aquarium, according to the weekday viewing situation only feed seven or eight percent full, do not feed at night.

Generally speaking, the number of bait should be 1-2 times a day, once in the morning and once in the evening, and once in the evening should be early rather than late, and should be fed around the evening. In case of weather changes such as showers and cooling in the evening, a small amount of bait should be cast or no bait, and bait can be done early in the morning. After each bait, the amount of bait should be decided according to whether the koi can be eaten within an hour, and at the same time, the color of the feces should be used to judge whether the koi has good digestion and decide the amount of bait to be fed next time.

3. Water quality and temperature:

Koi fish need high water quality conditions, and pH is appropriate. The dirty and whitish water in the aquarium is prone to dead fish, and in this case, measures should be taken in time or all the water should be replaced. The water temperature is generally kept between 15 and 25 °C.

Water change is a simple and direct way to adjust the water quality of the aquarium, the day before the water change needs to take measures to dry the water, the tap water can be put into the box after standing for 24-48 hours, the water drying has the effect of increasing oxygen and making chlorine overflow.

Aquarium rearing koi requires clear water and fresh fish, so keeping the water clear is the top priority. In the hot summer, it is necessary to clean the pollution once a day, and the interval can be appropriately extended in other seasons. The method of cleaning the dirt is to use a rubber tube to suck off the koi feces, residual bait and other materials deposited at the bottom of the aquarium, and then add the same amount of new water.

To raise koi fish, it is necessary to change the water quality in time.

The problem of water quality mainly depends on whether the filtration system is reasonable, and biochemical and physical filtration are indispensable.
