Methods of raising small turtles

At present, the main source of fish farming is tap water, but tap water contains a lot of chemicals such as chlorine, which must be treated before it can be used to add color.

Some professional color friends specially prepared a water tank, and a filter box was set at the water inlet of the water tank, which was filled with filter cotton and activated carbon.

After such treatment, the water quality of the incoming water will become clear, otherwise the tap water will be directly injected into the water tank, and its water quality will be turbid, so it will be compared after treatment.

Trouble. After water is filled, start the air pump to pump air (commonly known as "aeration") and pump air for more than 24 hours. If there is no condition to equip the water tank, then

It can be treated with special color chlorine remover or water quality stabilizer. If the amount of water exchanged is small, there is no problem.

I would also like to add that local fish can generally adapt to the quality of local tap water, except for the above treatment.

It is necessary to use PH lowering agent to adjust the pH of water or to soften the water quality by ion resin filtration, which is a waste of money. But if it is imported fish or something, it depends.

That's settled.

Change water

Changing water is a very important step to improve the color of bare cylinder, but the fundamental purpose of changing water is to keep the water quality stable, not just to keep it.

Clarification of water quality. Therefore, we should master the following aspects when changing water: First, according to this principle, we should control the quantity of changing water at a time, and change more water and less water.

It's not good either, especially if the water quality of the feeding tank is well controlled, so it's not necessary to change a lot of water every day. Second, change the water slowly.

You can't directly pour the bucket into the feeding barrel, but slowly inject new water into the feeding barrel. On the one hand, you should keep the influence of water flow on colorful at a minimum.

Degree, on the one hand, also makes the new and old water quality in the tank change gently after injecting new water, so that colorful gradually adapts.

Water quality control

Clear and stable water quality is not only conducive to the growth of bright colors, but also makes viewing a pleasure, but compared with straw tanks, the water quality in bare tanks is difficult to control.

Greatly increased. I want to offer some ideas here: 1. Reasonable configuration of filtration system. Generally, two sets of water filters are equipped in the bare cylinder, one of which is the upper filter.

Water filter and a set of biochemical cotton water filters. The power of the upper water filter should not be too large, which is mainly used to extract the dirt at the bottom of the cylinder. When installing the layout, you should consider the filter.

The water flow generated by the water outlet of the water filter just drives the dirt at the bottom of the cylinder to flow to the water outlet of the water filter, thus achieving the best filtration efficiency. Upper water filter

The filter box is equipped with filter cotton, biochemical cotton and activated carbon from top to bottom, and the filter cotton is cleaned at least once every two days. Biochemical cotton water filter is mainly used for

To filter the tiny particles in the water, keep the water clear, and at the same time play the role of pumping air and increasing oxygen. Because colorful likes the environment with gentle water flow, so for feeding,

In small tanks or tanks for colorful young fish, the upper water filter is closed most of the time, and it only works when the bottom of the tank is cleaned before and after feeding, while the biochemical cotton filter.

It is best to keep the water heater working for 24 hours. This configuration, coupled with frequent and regular water changes, will keep the water quality in the tank very good after a period of time. Second, keep

Ideal weak acid water quality. Qicai likes to live in weak acidic water with a PH of 6.2-6.8. Generally, when the PH value of tap water exceeds 7.0, the PH value will be adjusted.

It's too much trouble for amateur color growers, so I offer you two methods: the first is to plant aquatic plants with wide leaves (such as crown grass) in the breeding tank.

When some leaves turn yellow and rot, don't remove them immediately, and keep soaking for a while, which will help lower the PH value. Because in Amazon's colorful hometown,

In the basin, the riverbed is covered with fallen leaves of tropical forests, which are soaked in water for a long time and rot, eventually creating local weak acid water quality. The second is feeding.

Strengthen the filtration of the water supply tank and change the water as little as possible. After a period of time, the water quality of the feeding tank will naturally become weakly acidic "old water". This method is more suitable.

Hay vat and experienced friends.

How to choose feed

-How to choose the bait for ornamental fish

How to choose the bait for ornamental fish

In Xian Yi, keeping ornamental fish as pets has become a cultural and recreational activity for all ages. Since I am a pet, I always hope that it will grow well and quickly, and I will not hesitate to buy the best bait to feed it. But what is the best bait? I don't know, people follow the trend, sometimes they spend a lot of money, but they feed the fish to death. I don't know why. In order to raise this precious fish and not waste money, we must understand what is the best and ideal bait. To judge the quality of bait, there must be a scientific and reasonable basic standard, which is summed up from the long-term fish farming practice of most people and is objective and accurate. According to this standard, it is easy to choose the best and ideal bait by measuring and comparing the existing bait.

Basic standard of bait:

1. Clean and sanitary, and cannot carry any pathogenic insects, parasites, viruses, miscellaneous bacteria and toxins. Long-term consumption can ensure the safety and health of fish. (prevent disease from entering the mouth)

2. The shape and size should be appropriate, and the original shape and nutrients can be maintained within one day after being put into water, without damage, loss, corruption and pollution. It is most important to protect the living environment of fish from being destroyed.

3. The formula is scientific and reasonable, the nutrition is rich, balanced and comprehensive, and it is easy to digest and absorb, which can completely meet the needs of fish growth and development for various nutrients. (Necessary function of bait)

4. Sweet glutinous rice is soft and delicious, and all kinds of fish love it. (Good appetite)

5. Easy to use, you can feed the fish without any processing after buying it. Can be preserved for a long time, neither rotten nor rotten. (Easy to use)

There are many kinds of bait, which can be roughly divided into natural bait and artificial bait. Natural bait includes fresh bait, frozen bait and dry bait. Artificial bait also includes frozen bait and dry bait. These baits have their own characteristics, and we need to analyze and compare them. It is necessary to choose diets that are rich in nutrition, balanced and comprehensive, clean and hygienic, free from protozoa, miscellaneous bacteria, viruses and toxins, so as to seek advantages and avoid disadvantages, and to exclude and stay away from dangerous diets that will make fish sick. Only in this way can fish farming get twice the result with half the effort, save worry and effort, and fish can grow healthily and vigorously without worries.

1. Natural bait: including 1. Fresh bait; 2. Frozen bait; Step 3 dry the bait.

1. Natural live bait: including red worms (nematodes, silkworms, water worms, etc. ), fish insects (Daphnia, cladocera, copepod, red spider, larva, etc. ), blood worm, rotifer, paramecium, bread worm, five-grain harvest, river shrimp, silkworm. Fresh bait conforms to the natural feeding lifestyle of ornamental fish and has a good appetite. All kinds of ornamental fish like to eat. Fresh bait contains a lot of nutrients such as protein and fat, but its effective substances are not much, accounting for only about 10-20% of its weight, and most of the rest is water. The nutrients of each fresh bait are partial, unbalanced and comprehensive, and some nutrients are relatively lacking. If only a single live bait is used to feed fish for a long time, it will seriously affect the health of fish because of unbalanced nutrition, resulting in thin fish and slow growth. Fish worms, red worms, blood worms, shrimps, paramecium and other fresh bait are caught in polluted waters or sewage sludge ditches. There are a large number of pathogenic insects, viruses, various germs and toxins inside and outside the worms, which pose a direct and potential pathogenic threat to ornamental fish. If this kind of fresh bait is fed for a long time, fish will be easily infected and germs will spread, leading to illness, poisoning and even death. Therefore, fresh bait is fresh. Master Jack Vatri of Czech Republic, a world-famous colorful breeding expert, has cultivated a series of varieties such as Tianzilan and Taiwan Province Red. His fish basically don't feed on raw bait, but completely eat Hamburg artificial compound bait.

If you want to feed fresh bait, you must wash it repeatedly, disinfect it strictly, and then freeze it, so that the insects will freeze to death, and the pathogenic insects and germs carried by the insects will almost die. After these procedures, it is safer to feed the fish, but the virus carried by the insects will not freeze to death, and various toxins still exist, which may also make the fish sick. Fresh bait is not easy to preserve, and it also seriously pollutes the water quality when feeding. Weighing the pros and cons, since there are other high-quality and safe baits, there is no reason to put live baits that are dangerous to cause disease into fish tanks. Live bait is not suitable for ornamental fish to eat in order to prevent fish from getting sick or staying away from this bait.

(1) Red worms (nematodes, silkworms and water worms) are the most common live bait. They often make holes in ditches or swamps and are reddish in color. Rich in nutrition, containing a lot of fat and protein, suitable for raising small and medium-sized tropical fish. However, because it is usually collected from heavily polluted waters, it not only contains a lot of parasites and germs, but also contains excessive chemicals, heavy metals and toxins. At present, it has been considered as the main cause of illness, chronic poisoning and death of ornamental fish. Washing with plenty of water before feeding may not wash away parasites, bacteria and toxins. In order to prevent fish from getting sick, it should be used as much as possible to feed ornamental fish, especially parent fish for breeding.

(2) Fish insects (Daphnia, Cladocera, Copepoda, Crab, Red Spider, Pale Insect, etc. ) is a variety of small crustaceans with a diameter of about 1-2 mm, which can be seen everywhere, with about 100 species. These fish worms can feed ornamental fish. Body color varies according to the food they eat and the environment they live in, including brown, reddish brown, gray and so on. Fish and insects live in slow-flowing and fertile water, cluster together and swim smoothly and slowly. Its rich nutrition not only contains amino acids, but also contains fat and calcium necessary for fish growth and development. But it carries all kinds of viruses and miscellaneous bacteria inside and outside, which will enter the aquarium with it and infect all ornamental fish in a short time. Therefore, it must be cleaned and disinfected repeatedly before use.

③ Blood worms (red-banded worms) are chironomid larvae. Blood worms with a body length of 1-2 cm are the prey of medium and large fish. Chironomid mosquitoes don't bite people, and the blood of larvae contains heme, so the whole body is red. Mostly in still water mud, occasionally swimming in the water. Blood worm is rich in protein and organic nutrients, and it is a favorite food for ornamental fish. Blood worms with a large number of pathogenic bacteria and microorganisms are easy to cause fish diseases, so they cannot be fed directly to fish. Generally, blood worms bought in fish markets are kept in clean water for a few days, changed with water 1-2 times a day, thoroughly cleaned and detoxified, disinfected with drugs, and then frozen in the refrigerator, which is safer. When feeding, take some frozen blood worms, thaw them and put them in. However, people who really raise fish well will not take frozen blood worms as the staple food of fish. On the one hand, even after freezing sterilization, there is still a certain risk of blood worms. On the other hand, it is difficult for fish accustomed to blood worms to change their food into other kinds of bait. Therefore, blood worms are generally only used as auxiliary bait to adjust the appetite of ornamental fish.

④ Rotifers are small zooplankton, also known as "big gray water". There are more than 20 kinds of common rotifers, most of which are gray, and their body length ranges from 100-500 microns. Ornamental fish are mainly produced in fresh water, lakes, swamps, reservoirs and other places, and are very important bait for breeding young fish. Can be used to feed young fish.

⑤ Paramecium is a protozoan, called "little gray water", which is a single-celled animal with only one cell. It's hard to see with the naked eye, and observation under the microscope is like straw sandals, so it's called "paramecium". Widely distributed in rivers and ponds. This is the opening bait for young fish.

⑥ Breadform has high nutritional value and is rich in protein, hormones, calcium and phosphorus. It is the best live bait for fish. The contents of phosphorus and calcium increased when the bread worm pupated and shelled, and the scales were bright and the color increased after the fish ate them. The brooding rate of parent fish fed with pupated breadworms before estrus and spawning will increase and their larvae will be healthier. Bread form is mainly used to raise arowana and large silk fish.

⑦ Artemia is a crustacean, a nauplii just hatched from eggs, which has high nutritional value and is widely used as open bait for various ornamental fish larvae (especially suitable for feeding colorful angelfish and colorful angelfish larvae). It is very convenient to use and can be hatched at any time, but the price is slightly higher. Adults grow up with less meat and more skin, and their nutritional value is low. The body fluids of dead insects in the market have been lost, leaving only two layers of skin, which has no nutritional value and seriously pollutes the water quality. Fish don't like to eat, so it is very troublesome to wash it repeatedly to remove salt water and sewage.

2. Natural frozen bait: Because fresh bait contains a lot of pathogenic bacteria, microorganisms and toxins, it is easy to cause fish diseases, so it cannot be directly fed to ornamental fish. Generally, the fresh bait bought in the fish market, after repeated cleaning, strict disinfection and sterilization, is frozen in the refrigerator. Frozen bait is easy to store and easy to use. Every time feeding, part of the frozen bait is thawed and fed. Now there are also finished frozen baits for sale in the market, and the quality is uneven, so be careful when buying them.

① Frozen blood worm: Blood worm is rich in protein and organic nutrients, which is a favorite food for ornamental fish. Blood worms with a large number of pathogenic bacteria and microorganisms are easy to cause fish diseases, so they cannot be fed directly to fish. Generally, blood worms bought in fish markets are cleaned and disinfected, and then frozen in the refrigerator to make frozen blood worms. But people who really raise fish well will not take frozen blood worms as the staple food of fish, because even after disinfection and freezing, there is still a certain risk of disease.

(2) Frozen red worm: It has high nutritional value and is directly frozen with raw bait, which has a high probability of carrying parasites and germs. It is not recommended to eat.

③ Frozen shrimp: There are two kinds of frozen shrimp: adult shrimp and juvenile shrimp (nauplii). After the frozen mature shrimp melts, the body fluid has been lost, leaving only two layers of skin. The main ingredient is phosphorus, which has no nutritional value and fish don't like it. Putting it into water seriously pollutes the water quality. Shrimp seedlings (nauplii) harvested by freezing have high price and high nutritional value. If it is not convenient to hatch harvested shrimp larvae (nauplii) to feed young fish, frozen harvested shrimp larvae (nauplii) can be temporarily replaced. But frozen ones are never as nutritious as those you just hatched, so it's better to hatch them yourself.

3. Natural dry bait: a dry bait made by drying raw or dead fresh bait naturally or mechanically. It is easy to store and transport. However, in the drying process, a large number of nutrients are lost, and the appetite is poor, and fish do not like to eat. The use value is low, and few people use it now.

① blood worm drying: air drying or freeze drying technology is used to dry and preserve blood worms. Dried blood worms carry less bacteria and are safer than frozen raw bait. The rehydration of dried blood worms prepared by freeze-drying technology is good, but the price is too high.

② Dry bumper shrimp: After drying, only the skin is left, with high salt and phosphorus content, and no nutritional value, so the fish is not suitable for eating.

(3) Dried fish worms: dried with water worms such as Daphnia, which are basically skins and fish don't like to eat them.

2. Artificial bait: Artificial bait can be scientific and reasonable in formula, rich and comprehensive in nutrition, free from parasites and bacteria, clean and hygienic, and has little pollution to water quality. Undoubtedly, it is the most recommended aquarium culture today, which is not only more economical, but also more time-saving and labor-saving, and it is easy to control the feeding amount. There are many kinds of artificial bait, including 1. Fresh frozen bait; 2. Dry the bait.

1. Artificial fresh frozen bait:

① Frozen beef heart: degrease beef heart, cut tendons, crush and freeze it for later use, and put it into water when it is used. Cattle heart has a good appetite, and fish like to eat it, but it seriously pollutes the water quality. Fish lovers regard the cheap beef heart rich in protein as the staple food of ornamental fish. Although beef heart is actually meat with high protein content, it is still a single food with incomplete nutrition and many nutrients. For example, feeding only a single cow heart for a long time will easily lead to unbalanced nutrition of fish, resulting in slow growth, stunted growth, dull body surface and physical defects, which will seriously affect the ornamental value and commercial value of fish.

② Frozen hamburger: In order to make up for the deficiency of beef heart malnutrition and let the giant salamander eat well, fish farmers added beef liver, chicken, eggs, fish, shrimp meat, comprehensive vitamins, carrots, shrimp, enzymes, minerals and other materials to make a sumptuous Manchu-Chinese banquet-Hamburg.

Hamburg is an ideal high-grade fish food with the most abundant and comprehensive nutrition and the most scientific and reasonable formula. At present, the existing bait, whether fresh, dry, live or dead, artificial or natural, is not comparable to Hamburg. But Hamburg also has a fatal weakness, that is, "dirty water, big waste." Due to improper preparation method, when the frozen hamburger is fed in fish tank water, it will quickly melt and disperse into powder particles of different sizes, and the fish will eat the particles suitable for their mouth size, leaving the larger particles and smaller powder particles inedible. Added comprehensive vitamins, carrots, shrimps, enzymes, etc. They are all dissolved in water, but the fish can't eat them. These lost silt and various elements dissolved in water are soaked in water and deteriorated. This fatal weakness of Hamburg has brought great inconvenience to the use, hindered the popularization of Hamburg, and made Hamburg unable to be recognized and utilized by the majority of fish farmers for a long time.

(3) New frozen hamburger: a new type of hamburger refined by new formula and new technology in order to solve the problems of easy pulverization, dispersion, waste and serious water pollution when hamburgers are put into water. It looks like a blood worm and is convenient for fish to eat. When put into water, it will not be pulverized, dispersed or turbid, and all fish can be eaten, without wasting fish food and polluting water quality. Completely solved the fatal problem of "big water waste" in Hamburg, thus highlighting the use value of Hamburg, which is an upgraded product of Hamburg and is welcomed by the majority of fish farmers.

The new hamburger is clean and hygienic, without any pathogenic insects, viruses and miscellaneous bacteria, and the fish is safe and healthy for long-term consumption. Its formula is scientific and reasonable, and its nutrition is rich and comprehensive, which fully meets the needs of fish growth and development. Long-term consumption, natural and gorgeous, robust and healthy, growing rapidly and thriving. The new hamburger is soft and delicious, and all kinds of fish like it. Can be used for feeding various ornamental fish and soft-shelled turtles, and is more suitable for feeding high-grade "Caixian" fish. In all countries of the world, it has indisputably become the top staple food of all kinds of ornamental fish, pet turtles and advanced colorful angelfish. The newly bought hamburger can be fed to fish without any processing, which is convenient to use, saves effort and time, and makes fish farming completely free from cumbersome operations, which becomes a relaxed and pleasant thing. The new hamburger makes the artificial bait (fish food) of hamburger really enter the practical stage.

2. Artificial dry bait: there are flake type, granule type, patch type, puffed type, etc. Dry bait has poor palatability. It is hard before it softens in water, and fish don't like it. When softened, it is powdered into a foam residue, which the fish can't eat, and it is all wasted, which has become the source of water pollution. Dry bait is not easily digested and absorbed by fish because the intestines of fish are very short. Even if the fish ate the dry and hard bait, when it was soaked in the intestines, the bait had moved to the vicinity of the anus, and it was discharged before it could be absorbed, without absorbing any nutrients, and it was all wasted. Undigested feces accelerated the deterioration of water quality. The dry bait consists of fish meal, bone meal, feather meal, blood meal, bean cake powder, vegetable cake powder, soybean meal, wheat flour and starch. These raw materials are rich in oil, which is easy to oxidize and produce toxins after a long time, making fish anemic and thin and die.

① Slice bait: The artificial bait developed in the early stage is mainly flake bait, which has been used up to now. There are all kinds of flaky and flaky baits on the market, which will absorb water and soften when put in water or attached to the wall of the pond, and then the fish will slowly suck. Flake bait is more suitable for small fish, such as guppies, bream and lamprey. And it is convenient to feed, but the residual bait is scattered and precipitated at the bottom of the pool, which is not easy to remove, and it is easy to cause water pollution after a long time.

Growth flake bait: flake bait is made of more than 40 different raw materials, with high protein content, which can promote fish health. Suitable for freshwater fish and marine fish.

Brightening flake bait: it can promote fish to increase color, because it is artificially colored, and the color looks unnatural, which is also harmful to the health of fish. It is not recommended. Suitable for freshwater fish and marine fish.

High-protein flake bait: iodine, seaweed, mysid shrimp, bumper shrimp and some plankton are added to the ingredients, which is suitable for tropical fish such as cichlids and flounder and angelfish in marine fish.

Vegetable flake bait: it is a kind of plant bait suitable for all herbivorous fish. Suitable for freshwater fish and marine fish.

Fish fry bait: fine and nutritious powder bait. Suitable for freshwater fish and marine fish.

② Granular bait: It contains important nutrients, vitamins and trace elements, and is suitable for feeding various types of large fish. Suitable for freshwater fish and marine fish.

High-protein strip bait: it has unique suspension and is suitable for feeding fish to forage on the water surface. Suitable for freshwater fish and marine fish.

Ingot bait: suitable for feeding benthic fishes such as Silurus, Muridae, etc., and also for feeding reptiles such as turtles and lizards. Suitable for freshwater fish and marine fish.

(3) Sticking bait: It can be conveniently stuck on the fish tank wall to observe the growth state of pecked fish more carefully. Suitable for freshwater fish and marine fish.

④ Expanded bait

It is an expanded granular bait widely used in aquatic products and ornamental fish in recent years. In the manufacturing process of high temperature and high pressure, it can not only make the raw materials fully mature, but also have sterilization effect. But all kinds of vitamins and nutrients that are afraid of heat have also been destroyed. Expanded bait can be used to make floating or sinking granular bait products, which can keep intact particles in water for at least 3 hours. Therefore, puffed bait is a kind of bait with little pollution to water quality. It can be made into large particles with a particle size of 0.5 mm to 7 mm, or it can be put into an automatic bait feeder to feed at regular intervals, which is quite convenient to use. Because this kind of bait is mainly starch, its nutritional value is low, so it is difficult to meet the nutritional needs of carnivorous and omnivorous fish for protein, amino acids and multivitamins, and it is not suitable for carnivorous and omnivorous fish.

The preservation of synthetic dry bait must be sealed and moisture-proof. Although some baits are moldy and deteriorated, it is difficult for the naked eye to detect them immediately. If you feed the fish with this bait, the fish will suffer.

Through the above introduction, analysis, judgment and screening, the new hamburger meets the basic standards and is an ideal bait for ornamental fish. With the development of science and technology, new and better baits will appear for us to choose from.

Communication, if there is anything wrong, please correct me! Let me talk about how to choose milk and how to manage it.

Choose milk

1. First, we prepare a small jar suitable for small fish. The size of the jar is preferably 40 cm long, 25 cm wide and 35 cm high.

About water: There are two ways. The first one, which I have used for a long time, is half original water and half fresh water (cool enough for 24 hours). The second method is to use all the cold water.

3. put a water demon in the jar, and don't be too angry. It is best to adjust the temperature to be the same as or one degree higher than the water temperature of the original cylinder.

4. Pay special attention to fishing nets for small fish. The net sold is not very good and the mesh is too rough. Because small fish are especially tender and easy to hang, it is recommended to do it yourself.

Everything is ready, except for the east wind. Don't worry, as long as you catch up with the pro-fish and protect the fish, you can fight hard with your fishing net. Believe it or not, I will catch up with this situation many times, and I must find a way to catch the parent fish.

Draw the fish away, and then take out the small fish.

6. Last but not least, it is to quarantine the small fish. It's simple. Just put a needle in the small jar of the size mentioned above to celebrate the big jar. The whole milk picking process here has been completed.

All right.

Two. Feeding and management of juvenile fish

The quarantine mentioned above must be done for three consecutive days, that is, three consecutive days to celebrate the big day, and the quarantine is completed. Harvesting worms are generally chosen as bait for young fish after milk collection. Three hours after milking.

Never feed in the house to prevent the young fish from urinating urgently. In terms of feeding, I suggest adopting a way similar to grazing, that is to say, feed frequently and feed less, and remember not to raise small fish. My friend is very good at colorful. male

The way we feed fish is to feed striped fish, but we can't pass the stage of raising small fish. We have raised colorful fish three times, and now we have got some small leopard snakes from me, making a comeback for the fourth time. I've been here, too

From a period of time, people who initially raised colorful fish had a misunderstanding in breeding, that is, they couldn't wait for the fish to grow fast and were afraid of losing their small fish, which was not good. You know, the little fish didn't know how full it was, and it really arrived.

It's no use feeding it when it grows up. When it is full, it will never eat again, preferring to leave the food behind. Well, in a word, it is a truth to feed frequently and feed less. It is better to live if you owe. It usually takes ten to fifteen days to feed the adults.

Changed the bug.

Usually, it is best to install a light bulb on the small water tank. It is best to change the water twice a day, and change the water by half each time. Small fish like fresh water, and the water temperature must be the same as or slightly higher than that of the fish tank, not lower than that of the fish.

The water temperature of the cylinder is very important!

3. Change food and gas cylinders

1. Change food. Generally, the time for young fish to eat larvae is about 10 to 15 days. Take 15 days as an example. On 12 days, they began to add water. The method is as follows: test the water before you start feeding the fish.

Put a little, see if you eat it. Under normal circumstances, you will eat it, and then feed it to the reaper. Do it every other day according to the above procedure on the first day; Cook every meal the next day; On the third day, all the water was fed every other day for two days. At this moment,

The work of dumping insects is finished.

2. Invert the water tank. With the growth of small fish and the increase of food intake, the size of the small fish tank mentioned above is no longer suitable for the growth of small fish, so how to judge? 1. Look at the purity of water, in normal feeding.

In this case, the water can no longer be kept clean; 2. The small fish floats on the water after eating. At this time, the oxygen content of the water is far from enough, and the can is about to be emptied. The size of the cylinder is preferably 60cm-80cm, not one.

It's not good to pour it in a big jar. Small fish will grow big and small, and some fish farmers keep small fish big and very uniform. I think these are very important for fans. ......

4. The management of colorful Chinese fish is particularly important.

It is one of the important tasks to empty the tank in time, so that the fish can keep a relative density in the tank (of course, it is closely related to your daily management, such as changing water every day, every

The secondary water exchange rate is 1/2. Take 1.20 6045cm as an example, 2-3 working points of small fish can stock 1.50-200 fish. Fish 4-5 working points can be stock100-150; 6-7 China fish can be stocked for 60-

80 tails; China fish with a score of 8- 10 can raise 40-50 fish; Adult fish can be stocked with 30-40). Maintain a basic ecological balance and give fish a comfortable environment. Remember, 1. There should be enough oxygen,

It is best to put two sand heads to blow oxygen, and the gas volume is larger; 2. The filtration system should be matched, and the size and water capacity of your cylinder should be considered when selecting the filter element. (I will talk about the daily life of the filtering system separately in the future.

Management)

Let's talk about how to feed the fish for 2-4 minutes. When the small fish grows to 2 minutes, the food intake increases greatly. Feed it four times a day for a long time, 40 minutes to an hour, to develop.

A good habit, as long as you go to the fish tank, first, measure the water temperature by hand; Second, observe the state of fish, especially the feces of fish in the morning, if it is different from every day, there is no or very little.

These are abnormal manifestations, and we should pay attention to them. Normal feces should be short! And thick! And black!

The bait for small fish should be mainly water, and the longer it is fed, the better. Water is particularly easy to digest, and the stomach of small fish is not easy to have problems, which makes small fish grow fast, well and healthily. To 4-5 cm.

Start feeding hamburgers and red blood worms, and be careful not to let them eat childe. I once killed a fish. I should pour the food step by step, feed it first, and then I will gradually pour the food backwards. At this time, feed it three times a day.

Well, when the score is 8-9, just feed it twice a day until it turns into a fish.
