Breeding and management of arowana
Psychological preparation before raising a dragon An article published by a fish farmer on the Internet is worth reading. If you want to keep a dragon, first ask yourself if you can stand loneliness ... You often see Longyou calling for the nickname transfer of Ailong on the Internet, and you often see the exciting hair color sent by individuals who have just turned one year old and fishmongers. You often see Longyou inviting one good dragon after another without mentioning his half dragon, and seeing the young arowana who has just turned one year old. Really worried (what a good dragon? What? Not mine? ) is the most glorious period of arowana. What? Can't you hold on? Think before raising a dragon. Once you buy a dragon and go home happily, I'm afraid no one will think about where this dragon will go in three years or ten years. Although arowana is small, it is really a big burden to raise. Without adequate mental preparation, I am afraid I can't stand the test of time. There is no specific conclusion about the life span of arowana, at least there are few arowana. Let's have a funeral. The life span of arowana should be at least 20 years. For a long time, few people can hold on, (Yang I believe), because? Some people raise Xiaolong to Jackie Chan, and then raise him to look around. Few people have been with him for 20 years. At first, Mei Chen's two red dragons attracted a lot of praise and criticism at the same time. I am also interested in this kind of business. Disgusting, but fake fragrance? I've been a widow for five years, raising dragons. My dragon is not one year old and is not qualified to comment. It may not be as good as others then. So some people say that keeping dragons is an adult activity. On the one hand, there are financial reasons. On the other hand, whether you can peacefully stick to your interests is probably not the choice of fickle young people to pursue new things.
Correctly treat the growth of arowana. The maturity of Jinlong is the process of its growth, ranging from 3 years to 5 years. The maturity of the red dragon is longer, and there are also individuals who develop color in 8 years and 10 years. Did you wait? In fact, the hardest time to raise a dragon is the second year after raising a dragon. In the first year, the general interest was high, and the care of arowana was meticulous. This period is big, and the satisfaction in my heart is beyond words. However, in the second year, the growth of arowana began to slow down, and the monthly body length change of 1cm often made longyou unable to bear the loneliness of dragons and began to complain about the slow coat color. In fact, interest and patience are losing a little bit. However, during this period, my love dragon has just turned full and is maturing. Jinlong's body is covered with splendid armor day by day, and the red dragon's body is slowly bright red? Color, such a process is not the process that dragon breeders expect, nor is it a successful experience. Don't be swayed by other people's opinions.
Many friends post their dragons for everyone to appreciate, and praise is their favorite (no matter who they are, unless they are masochists), but many dragon friends have good and bad opinions, so you should be able to bear it in your heart, otherwise it is best not to post them. When people say this is a hybrid, the appearance is not good. This is an old fish. Where's your own dragon? Not pleasing to the eye, finished, in the near future, this dragon must not exist in this Tanqueray. Raising dragons is not? Others keep their own dragons, so let others talk about it. It is admirable to keep a red-tailed gold for more than 5 years. Love the new and hate the old, which wastes more time in communication and improves the appreciation. I have also seen many good dragons, so Qinglong has raised a red tail for a while, with a red tail and a high back, and a red dragon with a high back and a better back. Being fond of the new and tired of the old turned me into a happy breeder, who kept raising without a moment's peace and slowly consumed my patience. No one likes to farm all day without getting anything. The fun of raising dragons is experienced in the long process of arowana's maturity, and the fun of breeding offspring is rarely enjoyed in China. What? Can't try. I've always admired my friend Lone Dragon. The excellent young dragon was cultivated and raised in Tanqueray for many years? Brother Long, I'm afraid I can't stand this loneliness. Actually, no one can guarantee the future. Sample, should change or change, should sell or sell, but if you can keep arowana, maybe this persistence will affect your future. There is not a feng shui saying, maybe it is.
The required hardware aquarium is in natural waters, and arowana lives near the water surface and is unlikely to dive to the bottom. Therefore, the first consideration for raising arowana is the width. If the width of the aquarium is not wide enough compared with the length of the fish, it will cause the arowana to swim in circles in a certain direction, resulting in the bending of the fish's spine. To avoid these problems, the ideal aquarium should be relatively large in horizontal width and depth, which is generally needed. Generally, the fish tank for feeding arowana should be at least 120*60*60CM, and of course, it is best to have a fish tank above 150*60*60CM! And when feeding arowana again, it's best to put it in a big fish tank at the beginning, because if you feed a 60*35*40CM fish tank of 10CM, it will be changed in a few months, because it has grown up! It is easy to hurt it when changing the tank, so it is best to keep it in a big fish tank from the beginning to avoid the above situation: arowana is sometimes neurotic. People often come in and out, or children pat the fish tank, which will affect the mood of arowana and even affect eating, so it is best to set the fish tank in a place where it will not be disturbed often. Special reminder: Because arowana fish tanks are generally large, you should also consider the bearing capacity of your floor. & Remember! Remember! Remember! ! ! ! ! !
Indoor arowana breeding generally uses lamps, which can't let the fish receive sunlight. Only plant lamps or sun lamps can supplement the lack of sunlight, increase the color of fish and promote the metabolism of arowana. & There are two kinds of lighting equipment in the market, one is underwater lamp, and the other is the upper lighting of aquarium. Now there are many lights to choose from, and the colors displayed by its arowana are different. Nightlight suggested adding a nightlight on the top of the tank, which can be opened all year round? In order to prevent arowana from moving slightly in the dark, the main function of air pump is to increase dissolved oxygen in water, and it can also create an atmosphere of water tank when used properly. Types can be divided into three types: AC-specific, DC-specific and AC-DC dual-use, and there are also many brand forms on the market. Trachea and alveolar trachea are in a single form; Bubble stones can be divided into two materials, one is wood and the other is sand. The shape of wood does not change much, but the shape of sand changes greatly, which can shape various shapes. Its function is to separate the air delivered by the air pump through the trachea more finely and increase the dissolved oxygen in the water. Filter In fact, the excrement of all carnivorous fish is easier to decompose than feed, so just use an ordinary filter. If you have a lot of arowana or mixed fish, you can also consider using a trickle filter. Now most filters (below six feet) on the market are trickle filters, so don't worry.
The bottom of the customized fish tank must be filtered, and its filtering effect is really good! The function of the filter is to pump the impurities suspended in the water into the filter through the water pump motor, filter out the impurities, and then flow into the aquarium from the water outlet, resulting in the circulation of water flow and oxygen supply. Filters can be divided into three types:
1. water filter;
2. The upper filter of the water tank;
3. Water tank external filter.
You can buy different shapes according to your personal preference. The filter materials in the filter tank are indispensable, including filter fiber cotton, activated carbon, zeolite, medical stone, ion exchange resin, ceramics and so on. Its function varies according to different species, and it produces physical, chemical and biological effects, so as to deodorize, filter impurities, adjust pH, remove organic matter and heavy metals, and reduce the content of harmful toxins. Although heated arowana can adapt to harsh environment, if the water temperature changes too much, it will also produce uncomfortable symptoms. Therefore, a set of good quality temperature control equipment is essential. Heating rods can be divided into three types: glass, timing and ceramics. When purchasing, the wattage of the heater is determined according to the size of the fish tank, which is simply converted into electric heating per 60 liters of water 150 watts. Because of the different manufacturing materials and technologies, the heater should be carefully selected to avoid endangering the life of fish. The heating power of the heater varies from 50w to 500w. Pay attention to whether the wattage indicated on the product is true when buying, and try to calculate whether it is standard.
Its function is to adjust the water temperature to a constant temperature suitable for fish survival, which can be divided into:
1. traditional type: the temperature is controlled by the temperature sensing reed;
2. Electronic: the thermostat sets the temperature, and the temperature sensor controls the heating or cooling of the heating rod. Thermometer Thermometer is a small thing, but it is an important instrument. Without it, it is impossible to know the temperature of aquarium water. With the help of thermometer, it can be judged whether the water temperature is normal, and if it is abnormal, it can be treated immediately. There are four kinds: mercury, alcohol, temperature sensor and electronic digital display. The function of ultraviolet germicidal lamp is to inhibit the generation and sterilization of algae spores and prevent the spread of diseases. The function of the pump motor is to promote the circulating water flow in the aquarium and increase the exercise of fish, because arowana has the habit of swimming backwards. If an air pipe is installed at the water outlet of the water lifting motor, the oxygen content of the water can be increased.
The suitable space environment (aquarium) directly affects the growth and physical development of arowana; Small environmental space will make the growing arowana short, chubby or hunchbacked. The correct feeding method must provide the environmental size according to the size of arowana, which is basically three times the length of arowana as the basic length of the fish tank. Balanced bait The nutrition of bait should be balanced. In addition to the staple food fish and shrimp, it can also be matched with other fish foods to avoid arowana's partial eclipse. The amount of bait should not be too much, and it should be controlled well, usually twice a day, once in the morning and once in the evening. The quantity control is based on the maximum consumption of arowana (that is, the amount of food you don't want to eat) minus 25% as the best feeding quantity. The advantage of controlling food intake is that it can avoid the overweight and unresponsiveness of arowana, make arowana lively and increase its affinity with its owner. The most important thing is to judge the health status of arowana. For example, the usual food intake is five shrimps and two tail fish, but it can't reach this amount for several days, and it is decreasing day by day, so it can be concluded that there is something wrong with the fish! ! The reason can be human shock, water quality change or disease infection. No matter what causes the sharp drop in food intake, it should be dealt with as soon as possible.
The purpose of the water lifting motor is to increase the dissolved oxygen in the water and the speed of the water flow. Arowana lives in nature, especially in wide rivers. It must shuttle through the rivers to find food and have enough activities. However, in the limited space of the aquarium, under the careful care of the owner, it is easy to eat nutrition because of low activity, which leads to weak body and weakened resistance and gain weight. Adding a water pump motor can make up for the shortage of aquarium and promote the physical strength and resistance of arowana. The beard with extended momentum is an extension of Arowana's momentum. If it is broken, short, stiff and crooked, its majesty will be greatly reduced. If you want to cultivate a straight beard, you must first prepare a space suitable for activities to prevent the beard from breaking and deforming. In the environment of insufficient space, arowana will constantly rub the cylinder wall with the jaw tip because it is too narrow, which will hinder the growth of beard and make the jaw tip form sarcoma under long-term friction, which will affect the appearance.
Attention should be paid to prevent beard injury.
1. No decoration. Such as rockeries, stones and landscape materials.
2. Don't feed in the corner of the aquarium, but in the middle of the aquarium.
3. Don't pat the fish tank to scare the arowana.
4. The upper part of the aquarium is covered with glass, pressed with heavy objects and rounded at right angles.
All the above four situations can prevent arowana from being hurt when chasing food or jumping in fear. If the beard is damaged and broken, the recovery will be different according to the age of the fish. Usually, young dragons recover their growth strength, while the growth rate of big arowana slows down or even stops. There are two kinds of broken whiskers:
1. It is difficult to recover because it is broken by roots. It's hard for even young dragons to grow taller.
2. If the root is not damaged, decide whether to let it grow naturally or acupuncture to promote its growth according to the broken condition. If the beard is injured and wants to be broken, it needs to be cut off to avoid deformation when it heals later.
Needle insertion promotes the growth of beard. If the root is cut off or the beard is not long after cutting, needle insertion can promote the growth in the following ways:
1. Prepare sterilized fine needles first.
2. Anesthetize arowana.
3. Put the anesthetized arowana on the plastic sheet.
4. Needle the root of the beard of Arowana with a fine needle until it is bleeding and swollen.
5. put it back in the fish tank, add an air pump to pump it up and wait for it to regain consciousness, and add appropriate amount of antibiotics.
This kind of acupuncture operation is best carried out by experts or senior personnel with experience in arowana operation.
3. Acupuncture the root of arowana beard to avoid and slow down the downward gaze. The eyes of arowana should be flat, bright and beautiful, but most arowana kept in aquariums stare down. The eyes came into being. The reason for looking down is the accumulation of fat in the eyes. In addition, because the fish tank is located in transparent body, it is a natural phenomenon that arowana is attracted by the flat environment and watched for a long time. The way to avoid arowana's eyes looking down is as follows:
1. Feed floating bait (dry bait). If it is a live bait, you can stun it first and feed it quantitatively.
2. Turn on the lighting equipment at night or when you are not watching arowana, and enclose the aquarium with black cloth or opaque materials. If the eyes are slightly downward in the early stage, they can be covered with black cloth for a whole day, and the downward phenomenon can be corrected in one to three months. If you bow your head and shape it for a long time, it can't be corrected. In the aquarium industry, some people have tried surgical correction, but the effect is not obvious, and it is easy to hurt the fish eye. Readers should not try it easily. Looking down is not a disease, it is a natural physiological reaction, and the owner need not worry too much. The most important thing is the blending of love and emotion for the raised arowana.
The gill cover to maintain stable and normal water quality should be smooth and smooth, without contusion, wrinkles or whiskers. To cultivate beautiful fish, we should pay attention to the following points:
1. Don't put decorations, such as rockeries, landscaping stones, Shenmu, wood fossils, etc.
2. Keep the temperature constant. When the temperature is too high, the epidermis of gill cover and head will produce wrinkles, and the temperature difference between hot and cold is too large, resulting in gill turning.
3. Change the water regularly to maintain the best water quality.
4. Improve dissolved oxygen in water.
Prevention of gill infection In the case of gill contusion and injury, appropriate amount of antibiotics or special fish medicine should be put in to prevent bacterial infection of the wound and avoid rubbing the giant scales of the damaged arowana. Normal scales should be arranged smoothly and orderly to avoid damage or falling off of normal scales. The method of prevention is:
1. Don't put decorations, such as rockeries and landscaping stones.
2. Pay attention to whether arowana is infected with parasites or white spot disease, because arowana will grind its teeth and stop itching if it is infected. Wipe things.
3. Change the water regularly to maintain the best water quality.
4. Don't scare arowana.
5. Catch arowana, don't use nets, use plastic fish bags.
Treatment of exfoliation and deformity If the scales fall off, they can grow and recover after 3 ~ 5 weeks. Pay attention to water quality during the growth period to prevent bacterial infection and avoid scaling and deformation due to friction.
In case the scales are deformed, you can anesthetize the arowana, pull out the deformed scales and wait for it to grow back. The fins of arowana cultivated since childhood are like human hands and feet. If each fin is deformed, it will affect the swimming posture and overall beauty of arowana. Beautiful fins must be straight and straight, and the fin membrane is intact. To make the fins of arowana develop smoothly, it is necessary to start from the juvenile stage. First of all, the feeding space should not be too large. In too large a space, young dragons are easily frightened and swim around because of their unstable personality. When swimming around, each fin will contract, which will affect the development of each fin in the future. It should be kept in a small aquarium, which is 3 ~ 5 times the length of the juvenile fish, so that the juvenile dragon will not be frightened by people in a small environment. Moreover, swimming in a small environment requires turning around from time to time, and the fins will naturally unfold. When Xiaolong grows up and has a stable personality, he will move into a bigger aquarium.
Precautions to avoid damaging each fin
1. Don't put decorations, such as rockeries and stone landscaping.
2. Young dragons should not be mixed with other kinds of fish, nor should they be raised with more than one kind of fish.
3. Young arowana should be caught with the finest mesh, but arowana above15cm should not be caught with nets, and plastic fish bags should be used. Trimming operation of injured fin If the injured fin is a single stem fracture and the fin membrane is connected, it can be torn off from the lower half of the stem fracture along the fin membrane by hand and wait for it to grow again. If it is a multi-branch fracture, it needs to be trimmed with scissors under anesthesia.
Ask an expert to help deal with the fin shaft fracture. You should do it immediately, especially the caudal fin as soon as possible, because the caudal fin shaft is broken, and the fish moves by swinging the caudal fin when swimming, and the broken part will not fully recover; Other fins may heal naturally, but they will be skewed or deformed after healing.
After growth, the trimmed fin is more complete, but it will be somewhat wavy, but it is not a big problem. It is best to invite experts or people with experience in arowana surgery for anesthesia pruning.
Emotional sustenance
Raising arowana is an emotional sustenance and cultivation, because people who raise arowana have an experience that they can get some comfort when they get along with arowana at a low ebb. When they have arowana in their spare time, they often spend an hour or two unconsciously in their mouths. This is often the experience of many breeders, which shows the attraction of arowana. If interactive training is to produce emotional singing with arowana, it needs to be cultivated from the young dragon, because arowana has its own emotional world. To establish feelings with arowana, we can first restrain arowana by feeding at a fixed point and at a fixed time. Tap the box wall before feeding to attract the attention of arowana, and then feed it when it swims near the feeding port; After a while, arowana was no longer afraid of strangers and got to know its owner. As long as you tap on the wall of the box, you can swim right away. After that, you can try to shake the bait on the water to attract the love fish to swim and eat. After getting used to it, you can put bait into the water by hand to let the fish eat from your hands, and cultivate the habit of eating lightly from your hands. Then you can try to get in touch with arowana and reach a tacit understanding. In the meantime, as long as the owner approaches, arowana will naturally face the owner and shake its head and tail to welcome him, which will make the breeder feel quite warm.
In order to cultivate high-quality arowana, players themselves still have to make great efforts in the ecological structure of water quality. If the water quality is unstable, it will lead to "frequent ailments and frequent drug baths (and drug injuries)", which will not only cost money, but also have a great impact on the color of Arowana in the future. Remember! ………
Diseases and treatment of arowana In the natural environment, all living things will have different degrees of diseases, and some will be infected; External factors and activities can also cause different degrees of injury. Under the limited aquarium space and artificial control, although it provides the best living environment and equipment, it is different from nature, which affects its natural living conditions, causes physiological abnormalities and decreased resistance, and suffers from diseases. The reason of Arowana's illness is nothing more than bacterial and parasitic infections and negligence in human management. For dragon breeders with ptosis, the most troublesome and annoying problem is that arowana will lose its eyes, but the first thing to emphasize is that arowana will lose its eyes. If you are not ill, you must swim sideways, just because you have an eye. It's pretty ugly. Even the best dragons are on sale &; There are quite a few invisible fish in Japanese arowana magazine. We can't try to pursue the perfect Abenz. Are we dead too? First of all, we must understand that arowana is an ancient fish. Generally, ancient fish are very sensitive to the environment, and arowana will not lose its eyes in the wild. However, because of the changes in the environment in the fish tank, arowana has taken precautions. We often ignore the living environment and high sensitivity of arowana, so we suggest turning the fish tank upside down first. If you grow up in an unsafe environment for a long time, it will bring great life threats to yourself. As long as you are an ideal home for arowana, I believe arowana will also bring you good luck. Try to analyze several points that will make arowana lose its eyes. 1. Changes in foraging habits: In the natural environment, arowana forages for plankton in the water; In the fish tank, you are looking for fish and shrimp in the middle and lower levels. Some arowana, which have been raised by dragon owners all their lives, are live bait that will sink to the bottom of the water. Even if they let the fish catch themselves once, their eyes will never drop. 2. Perspective on the external scenery: Arowana can see through the external scenery in the fish tank, and they will pay attention to things moving on land. 3. Fat accumulation: It is easy to find food, and lack of exercise causes fat accumulation. 4. The way to raise dragons is to let the light shine upward under water. Some dragons will be raised after a period of time. 5. The field of vision of the eyes is too small, especially the cylindrical environment is most likely to occur in dark and poorly lit places. If placed in a poor light environment, arowana's vision will become shorter. Just when the lamp of the fish tank comes down, it will only illuminate the periphery of the fish tank and induce it to look obliquely downward. This unnatural action will make it difficult for arowana not to lose its eyes. 6. The position and water level of the dragon tank are too high, which makes the arowana bow its head instinctively, leading to blindness.
