Although the carp is a benthic fish, this does not mean that its range of activity is static. The seasons change, and the water temperature is warm and cold. Wind direction, air pressure, synod.
Change, water turbidity, water current, water level fluctuations, dissolved oxygen in the water body, bait environment, etc., will change the activity area of the fish at any time, so that they often move more sharply, if in a larger body of water, this is called 'migration'. Common carp are the same as other freshwater fish.
In contrast, there are common habits and special habits. These habits are mainly determined by the need for reproduction, the need for forage, and the need for aerobic survival.
Grass-loving habits: a variety of aquatic plants and aquatic plants.
The thriving waters are also home to a variety of plankton.
and a habitat for benthic organisms, where fish can feed on a hearty diet. Aquatic areas are also excellent ovulation beds for fish, and these places are a gathering place for fish during the breeding season every spring.
Top stream. HabitsA pond often has streams or canals filled with water, which not only brings a large amount of fresh bait to the fish in the pond, but also has a high degree of dissolved oxygen at the inlet and outlet of the water, which is an ideal place for fish to feed and take oxygen. The so-called "flag with the wind, fish at the top of the water", this is the truth.
Waves of the wide pond often set off large waves on the surface of the pond when it is windy, and the wind and waves push the surface plankton and some other food to accumulate in the downwind inlet, and these baits are pushed into the water by the waves, and this area becomes a natural feeding ground for fish. Where there are waves, the dissolved oxygen content of the water body must be high (this is the same as the aeration machine in high-density fish ponds). Based on the above two items, the fish have developed the habit of following the waves to the downwind.
Warming habitsWhen the temperature of the natural water body is low, it is obvious that all kinds of fish like to forage in sunny waters, and rarely go to the side of large shady slopes and shady water areas, and do not stay still for long periods of time in deep water with low water temperatures. Early spring and late autumn.
Leeward shallow waters are in the daytime.
It is relatively warm in the sun, and fish love to swim here to feed. When the temperature difference between morning and evening is large, and the water temperature in shallow water drops rapidly, the fish usually retreat to the deeper water where the water is relatively warm. With day and night.
As the temperature of the water rises, the fish will rise and fall day and night. On the contrary, in the summer high temperature season, the shallow water is cool and pleasant in the morning, evening, and night, and fish like to flock to it. During the day, as the air temperature and water temperature rise, the fish gradually move to the deeper water.
In the middle of summer, when the sun is scorching and the heat is unbearable, the fish generally cower in the deepest part of the pond. If you follow the above rules to "find fish", you can basically find their traces.

Yes. Precautions for raising koi fish.
1. Don't pour the koi fish into the fish tank or fish pond immediately, because there will be a temperature difference in the water, you need to soak the koi fish in the water with the bag, and let it stand for about 30 minutes, so that the water temperature inside and outside the bag is consistent, and then pour the koi fish into the empty basin with water, otherwise the water temperature difference is 2-3, and the koi fish will catch a cold and get sick.
2. If the newly bought koi fish is to be raised with the previous fish, it is best to raise it in 5/1000 salt water for a few days for isolation and observation, and it is necessary to carry out insecticidal and sterilization procedures to prevent the new fish from carrying pests and bacteria to the original healthy fish.
b) Koi fish suitable for water temperature:
The optimal temperature range for koi fish is 2 30.
Note: Koi fish can not resist sudden changes in water temperature, for example, the temperature difference of the water suddenly exceeds 2 3 Koi fish will be uncomfortable, the optimal water temperature for koi fish breeding is 20 25, the demand for more sufficient oxygen, suitable for living in a slightly alkaline, low hardness water quality environment.
3) What do koi fish eat?
Koi fish are omnivores, and insects such as crickets and earthworms can be eaten, and vegetarian foods such as bread crumbs and steamed buns are no problem. It is best to feed synthetic pellets, bait, bean cakes, vegetable cakes, bread crumbs, fish insects, clams, crab meat, turnips, duckweed, etc.
Note: If you feed more, you should change the water frequently, the more you feed, the worse the water quality.
4) Stocking density of koi fish.
The feeding density of koi fish is also required, and the general feeding density can refer to the density table of koi fish stocked in fish ponds, which you should tell you when you buy relevant containers. I'm too lazy to hit it here, haha.
5) Fish pond water treatment equipment.
When raising koi fish, you must pay attention to the cleaning of the breeding environment of koi fish, the good or bad environment determines the survival and survival of your favorite fish. We also said in the last issue that the fish can not be very good and expensive fish, but the equipment must be good.
In addition, if you want to raise aquatic plants, it is best not to raise them in a fish tank, because koi fish are going to eat aquatic plants, and the leftover residues are also easy to affect the water quality of fish farming. It is best to keep the aquatic plants alone and then feed them at regular intervals.

Hello; Yes, carp group activities generally occur around food; At other times, it is rarely social; This is because carp is the lowest of the vertebrates, so there is little social activity, even sardines and other fish that move in groups, but they are also formed in order to survive, and they are essentially the same as fighting for food;
Birds, on the other hand, are at the highest end of the vertebrate like mammals, and they are social and family-oriented.

Living in groups, when fishing, a fish is a nest.

Koi fish are distinctive animals.
Koi farming methods.
1. Feed. Koi is an omnivorous fish, whether animal or vegetable bait can be selected 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 feeding 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, otherwise it will cause adverse consequences, light will cause indigestion of fish, heavy leftover food will destroy water quality, it is best not to feed at night.
The bait must be strictly timed and quantitatively to keep the water fresh. Generally speaking, the number of bait should be 1 to 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, according to whether the koi can be eaten within an hour, colleagues refer to the color of the feces to judge whether the koi digestion is good and decide the amount of bait for the next time.
2. Eating habits. Koi fish are omnivorous fish that can be eaten by molluscs, debris of higher aquatic plants, benthic animals, fine algae or synthetic pellet bait.
3. Water quality and temperature.
The breeding conditions of koi fish are different from those of goldfish, it requires high water quality conditions, and the pH should be neutral. Whoever is most susceptible to dead fish in the aquarium should take measures or replace all the water in time. The water temperature is generally between 15 and 25 °C.
Based on the measured data and visual changes in water quality, appropriate measures are taken to prevent the occurrence of diseases and the death of koi fish. 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 tank after 24 to 48 hours of standing, the water has the effect of increasing oxygen and making chlorine overflow, is a necessary practice when changing the water.
Aquariums raise koi fish and require 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 suck off the sediment in the aquarium with a rubber tube.

Koi are omnivorous. 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 of 5-30 and grow at a water temperature of 21-27.
In addition to the water temperature and the abundance of bait can affect the growth rate of koi fish, the growth of female and male fish is also very different. The age of the koi is determined as in most fish, and the number of rings of the scales is measured, which indicates the age of the koi.
The largest producer of koi is Japan, which has the most mature breeding technology and equipment, and has a large number of high-quality, pure-blooded koi, which are sought after by enthusiasts from all over the world. Every year, they go to Hiroshima and Niigata in Japan, the birthplace of koi, in search of the carp.

1. The suitable temperature range of koi is 2 30, but it 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.
2. Sufficient oxygen is required, and it is suitable for living in a slightly alkaline and low hardness water quality environment.
3. Koi fish are omnivorous fish, molluscs, higher aquatic plant fragments, benthic animals and even fine algae or synthetic pellet bait can be eaten.
4. Koi fish are cold-water fish, so it is best to raise koi fish in hot places in summer with a depth of half a meter or more.
5. The water temperature and the abundance of bait can affect the growth rate of koi.

Koi is a variant of carp, the body shape is basically the same as that of carp, the body is spindle-shaped, the lower mouth, there are two pairs of mouth whiskers, there are pharyngeal teeth, a lateral line runs through the tail, and each fin is complete.
Koi carp has strong adaptability, is a wide temperature fish, adapts to the temperature from 4 to 30 degrees, the most suitable temperature of 20-25 degrees, the requirements for dissolved oxygen are relatively high, the feeding process should pay attention to oxygenation, like neutral alkaline water quality, because it is native to the local, he pH, hardness and other indicators are the same as the local water quality. Koi fish also have a wide range of eating habits, and are omnivorous and carnivorous fish, and like to eat benthic organisms, aquatic organisms, young leaves of aquatic plants, etc., and have a digging feeding habit.
Koi fish grow rapidly, generally 2-3 years to sexual maturity can reproduce, once a year in April to June, if the use of heating or other methods, can also be bred in spring and autumn. Koi fish have a long lifespan, with the longest reported to be over 200 years old, and their body length can reach more than 50 cm.

Generally speaking, koi fish are temperate fish with a suitable temperature of about 8 30. It is highly adaptable to the environment, but it is vulnerable to drastic changes in water temperature, especially when the temperature difference changes violently4 or more, a white film will appear on the surface of the body, which is a cold symptom, so be careful. Koi fish are omnivorous fish that can be used as food for plant fragments, bloodworms, earthworms, bread worms, silkworm pupa, rice, bread, and fruits.
Generally, the proportion of plant feed accounting for 60% and animal bait accounting for 40% is the most appropriate.

It is about 35 centimeters.
The koi fish comes from the variation of wild carp, which retains the living habits of the original species: under natural conditions, koi fish are benthic omnivorous fish, and eat both meat and vegetables. The bait spectrum is extensive, the snout bone is well developed, and it often arches mud to feed.
Captive-bred koi: koi carp as an ornamental fish has been domesticated by the fishery from about 5 cm, can eat artificial compound feed, koi are mild by nature, like to swim in groups, easy to raise, and have strong adaptability to water temperature. It can live in a water temperature of 5-30 and grow at a water temperature of 21-27.
Omnivorous. Koi fish are larger, up to 1 meter in length and weigh more than 10 kilograms. Sexual maturity is 2-3 years old.
The lifespan is long, with an average of about 70 years. Spawns are laid in April-May every year.

Cats are absolutely solitary animals and do not live in groups. In fact, there are very few cats living in groups, except for African lions, leopards, cheetahs, jaguars, cougars, and even lynxes live alone, not to mention tigers. Stray cats may appear in large numbers together, but they do not cooperate in hunting, nor do they form a fixed interconnected society, and they do not live in groups. >>>More

Snakes are social animals. They usually overwinter in caves or tree hollows in dry terrain, which can raise the temperature by a few degrees and reduce water loss in the snake's body. This place, where a large number of snakes gather in the wild, is often referred to as the "snake nest". >>>More
The color of koi manure varies according to the fish food fed, such as pellet feed, puffed feed, self-formulated feed, bread, steamed bread, rice, vegetables, etc. Generally, the feeding is puffed material, and the discharge of black or dark feces is normal, if the feces are light or gray-white feces, it proves that the amount of food is too much, the koi has indigestion, or the koi has an intestinal infection. It is recommended to put less feed in fish tank breeding koi to avoid indigestion and deterioration of water quality!
