How to raise a koi fish fish tank in summer?

Question 1: How does koi fish keep fish tanks? According to the water capacity, discharge every 5000ml 1 koi fish. Aquarium fish farming is mostly indoors, and koi fish can be seen more clearly from the perspective of viewing; From the prevention of fish diseases, it can be found early; Not affected by indoor natural environment and stormy weather, it is easier to control the changes of water temperature, water quality and light; In winter and summer, it can resist the change of weather; It can also avoid the harm of natural enemies.

Method:

1. Preparation of Aquarium

The specifications of fish tanks vary from fish to fish. As koi fish is a large ornamental fish, the size of the aquarium is generally 90 cm, 60 cm and 45 cm.

2. Planting of aquatic plants

The aquatic plants in koi fish fish tanks are different from goldfish, because koi fish is big and strong, and it is easy to pull them up, bite or eat them. The planting method should be improved according to this special situation. First, the glass plate 1 parallel to the front is embedded in the back of the aquarium/kloc-0 ~ 1 5cm, and fixed in the gravel, so that the1rectangular community is separated from the aquarium to plant aquatic plants, and this area is separated from the area where koi fish swims. The washed glass plate is slightly lower than the water surface by 1 ~ 2 cm, so that the water circulates mutually, which can not only absorb carbon dioxide in the water, release oxygen, purify the water quality, decorate the aquarium, but also prevent aquatic plants from being destroyed by koi fish.

3. Water quality treatment

Water quality has always been the biggest obstacle to bring koi fish into aquarium culture, but compared with the past, the development of aquarium technology is no longer the same, especially the development of filtration system is changing with each passing day. Whether it is material, type, filter, bottom draft tube, etc. Combined with microbial treatment, it can be said that modern aquariums can carry highly polluted fish culture. As far as aquarium culture in koi fish is concerned, how to control water quality? The following will be explained in detail:

(1) Change water regularly:

The frequency of water change is the same as that of a general fish tank, and it can be changed once a week, and the water change rate is 1/3 each time. Before changing water, pour an appropriate amount of water stabilizer, and then put the prepared new water into the fish tank. As long as it is treated with water stabilizer, tap water can also be directly used in fish tanks.

(2) Use of oxygenator: koi fish is large in size and consumes a large amount of oxygen, so it is necessary to install oxygenator to improve the living environment. Otherwise, the dissolved oxygen in the water gradually decreases, harmful gases such as carbon dioxide cannot be discharged in time, and the water quality is prone to deterioration and corruption, leading to koi fish's "floating head" due to lack of oxygen, and even death in severe cases.

(3) Suitable stocking density

Koi fish per 1 liter 1 cm is the most suitable culture density in koi fish aquarium, which can only be lower than this range and never higher than this standard, otherwise the water quality will not be maintained.

(4) Feeding mode of small amount and multiple meals

Koi fish's digestive structure is relatively simple, and there is no stomach structure, so the food eaten will be digested and absorbed by the intestines, and the excrement will be discharged, so it is easy to cause indigestion due to overeating, and excrement is also one of the important reasons that affect the water quality. The best way to feed is to eat a few meals, 6-3 times a day according to the time, and each time is limited to the amount that can be eaten in three minutes.

(5) Regular water quality monitoring

Water quality monitoring is particularly important for fish tanks in koi fish. Before changing water every time, harmful water quality factors such as nitrate (below 5ppm), phosphate (below 1ppm), nitrite (below 0ppm) and ammonium/ammonia concentration can be improved immediately by changing water, but the fundamental solution is correct management and maintenance. Please refer to another special report-Maintenance and management of fish tanks in koi fish.

(6) Emphasis on physical filtration.

If the physical filtering part can be added above the submerged filter, the residue in the water can be filtered by the physical filter material first, which will speed up the force of the filter, as long as the physical filter material is taken out and cleaned regularly.

(7) adding microbial preparation for treatment.

Biofiltration, the most important part of the filtration system, is dominated by microorganisms, which can naturally decompose organic matter, nitrite, nitrate and hydrogen sulfide in water. These microorganisms include nitrifying bacteria and photosynthetic bacteria. A sound ecological pool must have a complete microbial system, which is helpful to the rapid establishment of nitrification system in water if necessary.

(8) Adopt the way of landscaping.

Plant filtration is also a good way to maintain water quality. Garden landscaping is adopted, so that the water in the fish tank is diverted to the vegetation on the land through the bottom diversion pipe, and then flows back to the fish tank, and the ammonia and nitrate in the water can be absorbed and utilized by plants, that is, ... >; & gt

Question 2: Culture method of koi fish in fish tank 1. environmental requirement

Koi fish has no strict requirements on water temperature and quality. The suitable temperature range is 2℃ ~ 30℃, but it can't resist the sudden change of water temperature and the discomfort in koi fish when the temperature difference suddenly exceeds 2℃ ~ 3℃. The optimum water temperature is 20℃ ~ 25℃. It needs sufficient oxygen and is suitable for living in a slightly alkaline and low hardness water environment.

Second, the feeding requirements

Koi fish is an omnivorous fish, which can eat mollusks, fragments of higher aquatic plants, benthos, even tiny algae or synthetic granular bait. It is best to feed synthetic granules, bait, bean cake, vegetable cake, bread crumbs, fish worms, clams, crab meat, duckweed, duckweed and so on. Feed regularly to avoid stress reaction of fish.

Third, the choice of fish species.

Fish species with healthy fish body, no damage, no desquamation and other diseases, bright fish body, various colors and clear boundaries should be selected.

Fourth, the feeding density

The density of water cluster box is generally 60 cm× 30 cm× 15 cm, and 6 koi fish plants with body length 15 cm ~ 20 cm can be stocked. 8 can be stocked in 90 cm× 30 cm× 50 cm; 110cm× 30cm× 50cm can be stocked10 tail.

Key points of verb management (abbreviation of verb)

1. Check all parts of the fish.

Whether there are pests in koi fish, observe whether there are rotten fins, rotten mouths, perforations, loose scales, erythema and color variation.

Observe whether the fish is getting thinner, which is caused by malnutrition.

Observe whether the fish body is edema and whether the abdomen is drooping, which is caused by the fact that the female fish can't lay eggs and stay in the abdomen to rot. Fish will get pinecone disease when it is swollen, which is obviously caused by internal organs.

Observing whether the fish is bent is often caused by improper or excessive medication.

Observe whether the eyeball is normal. If it is abnormal, it is mostly caused by visceral diseases. Don't find it too late, there is no cure for eyeball collapse.

Observe whether the fish gills are open and closed normally. For dead fish and diseased carp, pull out the gill cover and observe whether there is deformation, foreign bodies, parasites and excessive mucus secretion.

Check your swimming style.

When koi fish is healthy, he will swim in all directions. When he is ill, koi fish will swim alone. When he is seriously ill, he will stumble and even have no strength to stop swimming and even hit the wall of the pool.

Koi fish forms a circle in the corner of the fish pond or rubs the wall or bottom of the pond with his body, indicating that parasites have been attached to the fish. In severe cases, koi fish rubs his body, slaps his dorsal fin and pectoral fin, or jumps. If koi fish swims standing on his dorsal fin, it is generally a sign of nervous system diseases. Koi fish's winding body is an abnormal signal of koi fish. Staying still on the water is a danger signal. Being unable to stand upright is a state of losing balance. There may be something wrong with the swim bladder, or there may be parasites on the head. When he is seriously ill, koi fish will swim around.

Check your appetite.

Koi fish lost his appetite when he was ill. Try to observe the situation when feeding until you finish eating. Be careful not to let the leftovers sink and rot, which will affect the water quality and accelerate the occurrence of fish diseases.

There are many reasons for anorexia, such as hypoxia, ammonia increase, water temperature change, parasitic infection, virus infection, visceral diseases and so on.

Check stool

The fecal status in koi fish is also a sign of koi fish's health. Sometimes fish feces will appear on the surface of the pool water, which is proof of indigestion and should be stopped immediately. Feces lighter than pool water are not good. When koi fish's feces are white and gelatinous, it is a dangerous signal that the intestinal mucosa is shedding. If not treated immediately, enteritis and perforation will occur.

Question 3: How does koi fish raise koi fish in the family fish tank? It can be said that it is difficult to raise. I think the more I love koi fish, the easier it is to die. Pay attention to the water in the pool at ordinary times. You can use a filter sponge to filter water and let it have a circulation, such as backwater. At the same time, this filtration cycle can also play an aerobic role. Pay attention to water temperature and fish food in winter. It is suggested that the landlord feed with better semi-water or floating fish food. Can you buy some shrimps to feed them? You can also buy some corn, steam the whole corn and feed them one by one, so that their body color will be black and beautiful. You should also pay attention to the density of fish and plan how many fish to raise according to the size of the fish tank. Too much or too little is not appropriate. I used to raise six fish, from the young to 7.8 kg each, and each fish also had 1 1 kg. Later, I went out on a business trip and left it unattended with my friends, hehe. .

Question 4: Why did koi fish in the fish tank die after a period of time? The causes and solutions of koi fish's death in the fish tank after a period of time are as follows:

1, bacterial infection died. Equipment disinfection, food handling and fish quarantine must be done well;

2. Death caused by fungal infection. Equipment disinfection, food handling and fish quarantine must be done well;

3, parasitic infection and death. Equipment disinfection, food handling and fish quarantine must be done well;

4. The water temperature fluctuated violently and died. The daily fluctuation of temperature must be kept within 3 degrees;

5, water quality nitrite cumulative poisoning death. It is necessary to do a good job in testing and establish a powerful biological filtration system.

Question 5: How does koi fish in the fish tank feed koi fish in the fish tank? It shouldn't be too big, just a small and medium-sized koi fish. If you put it in an aquarium, don't expect it to grow very big, because as the saying goes, if you raise a big fish with a wide water body, the fish won't grow much. Of course, if the fish is small, the proportion of growing up will be larger. The principle of feeding is that you can feed at any season as long as you have an appetite. Generally speaking, your appetite is related to the water temperature. In a certain temperature range, the higher the temperature, the stronger your appetite and the faster the auxin level. The lower the water temperature, the opposite is true. Feed it 1-2 times a day, and the total amount should be controlled. You can make it full at once, or you can make it eat so much food twice. Every meal should be 7-8 minutes full. Don't leave any bait every time. Don't be too full. If you are always fed too much, you will get enteritis and die. Also pay attention to the color of the water, and change the water in time when it is dirty. Some people like to raise green moss water, others like clear and bright water, which doesn't matter, but water can't have obvious ammonia smell. If you find it, change the water immediately, otherwise it will poison the fish. There should be aerobic equipment. If there are many fish, always turn on the circulating pump or oxygenator, or you will die of lack of oxygen. It is worth mentioning that the fish tank should be covered with an anti-jump cover, which can be a fishing net or a cover like a fish tank on the market. Under the premise of ensuring adequate ventilation and dissolved oxygen, the cover must be covered to prevent the fish from jumping out of the tank and dying. Remember, remember!

I hope it will help you raise fish. I wish you success in raising fish!

Question 6: Summer is coming. How to cool koi fish? The water temperature in the fish tank is 30 degrees. Buy an aquarium fan to blow.

Question 7: How to keep koi fish in an outdoor fish pond so as not to die? How to raise koi fish in an aquarium? Compared with keeping koi fish in an aquarium, we should pay more attention to things all year round, and more importantly, we should take emergency measures when the temperature changes at any time (in this case, it refers to the outdoor fish pond in koi fish).

When a large number of our fish friends build koi fish Fish Pond, they will brush a layer of suitable cement on the inner surface of koi fish Fish Pond to prevent koi fish Fish Pond from seeping. Then we should do the first step, such as disinfection, water quality testing and other details of koi fish fish pond.

As a newly-built cement fish pond in koi fish, we all know that cement is alkaline, so it is necessary to remove the alkalinity of the wall and bottom of the pond before use. Otherwise, it is not suitable for koi fish to survive. The method of removing alkalinity from the wall of cement fish pond: Fill the pond with 0.25% phosphoric acid solution, soak it for1-2 days, then rinse the wall with clean water, and then soak it in dark green water for 10 days. Only when moss grows on the wall of koi fish Fish Pond in koi fish Fish Pond can the water be tested and confirmed to be safe before it is officially put into koi fish. When koi fish fry grow to 10-20cm, they can be fed in fish ponds.

Although koi fish lives in a water temperature environment of 2-30℃, koi fish will also be affected by sudden changes in temperature, and the physiological condition of koi fish will also be affected by changes in water temperature caused by seasonal changes. Therefore, we should also pay attention to the key points of four seasons management in koi fish.

Spring: In early spring, the fishpond should be covered with a fishpond cover, mainly to keep the water temperature stable. Early spring is when koi fish just came back from hibernation, and her body is rather fragile. Therefore, when feeding, it should be gradually increased from a small amount, and there are also requirements for the choice of feed. Because it has just recovered, we should choose more digestible feed to slowly recover our physical strength.

Summer: The water temperature is relatively high in summer, which is not conducive to the normal growth of koi fish. Therefore, the fishpond should be covered with this net cover, mainly to prevent the water in the fishpond from heating up sharply due to the hot sun exposure, so that green algae and phytoplankton can multiply rapidly, and the water quality is turbid, causing discomfort in koi fish and other diseases in koi fish.

Autumn: Autumn is the most suitable season for the growth of koi fish, and it is easy to get sick in the early stage, so it should be managed well. In this season, we can properly feed bait to improve the animal protein ratio.

Winter: In winter, the temperature will show a downward trend. The best way is to transfer koi fish to an indoor fish pond and keep the water temperature at 2- 10℃. During this period, it is necessary to feed properly, reduce water change, replenish water and remove pollution. Try to reduce the activity in koi fish's body, so as not to consume too much energy.

Variety collocation of koi fish in koi fish fish ponds: colorful koi fish is the main species, supplemented by luster and dark color. General breeding varieties are: red and white, Taisho tricolor, Showa tricolor, gold, platinum, Qiu Cui and light yellow. The breeding density is generally in a fish pond with a water depth of 30 cm and a square meter, about 15.

Question 8: How to raise a good family in koi fish? The first is the selection of koi fish, which is what we often say about how to choose a good koi fish. Of course, we don't have to cultivate the scales of giant carp, so as long as healthy fish have no other symptoms such as trauma and bleeding, are in good shape, have no genetic mutations such as head tilt and body bending, and are pure in color, that is, bright and thick in color, fish lines can form individual objects with certain artistic patterns. Actually, it's that simple.

The second thing is the choice and configuration of the aquarium: different specifications of the aquarium should be selected according to the conditions at home, but it should be noted that since koi fish is a large ornamental fish, the aquarium should not be too small, and the minimum water capacity should generally reach 60kg. Also, Kim likes to travel with a group, which consumes a lot of oxygen. It is best to have a certain number of oxygen pumps and filtering equipment to ensure the cleanliness of the fish tank and sufficient dissolved oxygen in the water. Another point is that we breed koi fish for my daily appreciation, so it is better to install lighting equipment in the aquarium. Most of us choose metal halide lamps.

The third thing to pay attention to is feeding koi fish: to put it bluntly, it is the choice of feed bait for koi fish and koi fish several times a day. As we all know, koi fish is an omnivorous fish, eating both vegetarian and meat. Koi fish's food: our common vegetables and fruits, Chinese cabbage, carrots, bananas, watermelons, bread, rice and so on. Bait, such as Daphnia, earthworm, loach, meat, shrimp, etc. , must be disinfected.

Generally, the amount we feed is 70% to 80% full, otherwise it will cause indigestion of fish, which may be koi fish's disease-enteritis, which will also destroy the water quality. Pay attention to regular and quantitative feeding to ensure the quality of fresh water. Most fish friends feed 1-2 times a day, once in the morning and once in the evening. It is better to feed in the morning than at night. In case of showers, cooling and other weather conditions, you should feed less or not.

The fourth thing is to pay attention to water quality and water temperature: although koi fish has low requirements for water quality, it is easy to get sick if it fails to meet the requirements of koi fish. The pH value of water quality needed in koi fish is preferably around 7.4. The water temperature can survive at 2-30℃, but it is best to live in low hardness 15℃-25℃ water. Fish culture in koi fish needs clean water and fresh fish, and maintaining the water quality of fish in koi fish is the first condition. Cleaning should be done almost every day in summer, and the time can be extended in other seasons. Cleaning is mainly to remove koi fish's excrement and leftover food in the fish tank, and then replace it with clean water.

Question 9: How to raise koi fish in an aquarium at home? Eating special feed and small fish and shrimp three times a day grows fast, but remember not to feed too much each time, which is easy to die.

Koi fish (Cyprinus carpio haematopterus) belongs to CYPRINIDAE, which is the largest family of all fishes, with more than 400 species of/kloc-0. It is a kind of advanced ornamental fish popular in the world today. It has the reputation of "living gem in water" and "swimming art". Because of its low requirements for water quality, miscellaneous eating habits and easy reproduction, it is praised and loved by people.

Question 10: How to raise koi fish 1 in the indoor aquarium, and how to choose and configure the aquarium.

Aquariums of different specifications should be selected according to family conditions. However, due to the different living habits of koi fish and goldfish, the aquarium should not be too small, and the general water capacity should not be less than 60kg. Koi fish is large, so it needs to be enlarged properly, and its water capacity is not less than 200kg. Due to the large amount of activities and strong oxygen consumption in koi fish, the aquarium should be equipped with water filters and oxygen pumps to ensure sufficient oxygen in the water and clean water quality.

2. Bait and feeding method

Koi fish is an omnivorous fish, and animal bait and plant bait can be selected as koi fish bait, such as Daphnia, earthworm, rice, pasta and so on. But it's best to choose synthetic bait for ornamental fish. It is especially important to note that the feeding amount should not be too large. According to the daily viewing situation, only 70% to 80% is enough, otherwise it will cause adverse consequences, ranging from indigestion of fish to leftover food, which will damage the water quality. Don't feed in rainy days and at night.

3. Water quality and temperature

The feeding conditions in koi fish are different from those of goldfish, which need high water quality, and neutral pH (PH7-7.4) is appropriate. Dirty water and white water in fish tanks are the most likely to cause fish death. In this case, measures should be taken in time or all the water should be replaced. The water temperature is generally kept between 15-25℃.

4. it is not suitable for polyculture

Koi fish is an omnivorous large ornamental fish, and all kinds of ornamental fish have different living habits, so it is best not to mix with other ornamental fish.

When raising koi fish, because everyone has different hobbies and different feeding conditions, the choice of koi fish should be based on personal hobbies, feeding level and family conditions. Pay attention to the following points when choosing:

One is to choose koi fish with a good figure. Because koi fish, like other fish, will have some genetic abnormalities, and some young fish will have congenital malformations, such as crooked head and bending. This kind of fish has no ornamental value and should be eliminated first.

Second, pay attention to whether the fish has obvious symptoms such as trauma and bleeding. Although some fish have no obvious traumatic diseases, they swim slowly, lose appetite, and often float on the water or stick to the corner of the fish tank, indicating that the internal organs of fish have other symptoms and should not be selected.

The third is to choose fish with obvious species characteristics, that is, to choose individuals with pure colors and artistic patterns.

The fourth is to pay attention to the embellishment of color and variety.
