It is an indisputable fact that the PH value of raising red dragons is low, and there are many methods. For example, adding CO2, changing water and lowering PH value. However, it is not recommended to add any external assistance. If you want to add it, just add black water or olive leaves These are all physical actions, and there will be no chemical action. They are the safest, cheapest and simplest. (Note: Supplementary personal opinions are different from relevant data) However, there is a simpler way to control water quality, and that is to change water. As far as my own water changing method is concerned, I sometimes change a 2*0.7*0.55 fish tank, a red dragon and two tanks of fish once a week, or once every two weeks, depending on my mood. Sometimes ten days, sometimes nine days, according to the length of time, determine the amount of water to be changed. To sum up my own experience, the time and quantity of changing water are the same. For a dragon fish, it is best to change the water once every two weeks, and the amount of water changed is a quarter of the total water. 1.5*0.6*0.6 cylinder, change it every ten days. Change the water by a quarter, and pay attention to the bearing capacity of your filtration system. In this respect, we should sum up our experience according to our own situation. It's hard to explain anything, as long as you feel that your method makes the fish red and your health is fine, it is the most correct method.
It is a good method to raise red dragons at low temperature. Personally, low temperature is helpful to the coagulation of red pigment. Provide a personal method (take Guangzhou as an example): I don't usually cool down in summer, so I don't care if the water temperature doesn't exceed 30 degrees. If it is too hot, just add a fan on the water surface, but it is best to add a small fan in summer, and it is best to control it below 30 degrees. Don't be lazy like me. I often go home and see that the temperature exceeds 30 degrees. (ha. . . . But fortunately, the fish is fine. In winter, it is best to use two temperature measuring sticks to control the temperature at about 28 degrees. Not less than 26 degrees, not more than 33 degrees, can be controlled at about 30 degrees. Nothing serious. Adjust the heating rod to 28 degrees. Turn the other one to 30 degrees. This is the best control method (note: the above is a supplementary personal opinion, which is different from the data). By the way, when changing water in winter, if you can't guarantee that the temperature of the newly added water is the same as that of the fish tank, change it every few days, and change it by one-sixth or less a day. Change the water many times, so that the water temperature will not fluctuate too much and the impact on the fish will not be great. If tap water is used directly, slowly pour it into the fish tank.
I won't say much about the main breeding varieties. Let's talk about my personal views and methods: it is an indisputable fact to feed red dragons with shrimp, but for my own red dragons, I basically freeze them when I buy shrimp and feed them, and then thaw them. But I freeze everything except shrimp and take it out when I feed it, so that the food will not be infected by viruses or bacteria, and I am lazy. I don't want to feed them for a few days or a day. It is easy to become a fish, and the fish will only die if they are hungry. I haven't fed fish for a week when I sent this document today. It's better for fish to be hungry. First of all, they are in good spirits and often swim. I don't want to move when I'm full. I don't feel so good. And from another point of view, hungry fish will be redder than red dragon, which can also be said from the body shape. Fat fish spread red pigment. It won't be very red without gathering. If it loses weight, it will be redder if it doesn't gather more red pigment. (Note: Personally, I think the red dragon is the staple food. You can feed something else when you are convenient or like, or you can feed the shrimp with something else for a long time. )
First of all, arowana is out at night in nature and hides in dark places during the day. Moreover, in nature, fish can only see the light above, and it is black all around. Therefore, there is no eye drop phenomenon of arowana in nature. Why are fish raised in fish tanks so easy to go blind? This question is hard to say. The main reasons are divided into several problems from my personal point of view. First, the transparency around the fish tank. Second, the time and intensity of lighting. Third, the low light of the fish tank water level. Fourth, genes.
Why do you spend so much time talking about this? The main reason is that my red dragon is mainly red, because the light and the size of the fish tank (which will be mentioned later) fall out of sight to varying degrees, which needs the attention of fans. I can't guarantee that I will be blind, but don't come out and hit me in the future, huh ~ ~ ~
(Note: The following are personal opinions, which are different from the information. As far as lighting is concerned, I mainly use underwater lights. I put water lights on both sides of the fish tank, and I will put them when the fish tank is long, so there will be no blind spots. And I >>
How to raise arowana since childhood
I. Environment:
The red dragon changes its coat color with the environment, which is also called environmental protection color.
1. Fish tank
The redness of the black tube is red, the blue tube is bright, the white tube is transparent and the redness is bright.
2. Arrangement position of fish tank
Arowana is unstable near the moving line where people often walk, which affects hair color; In secluded corners and basements, arowana is relatively stable and has excellent coat color.
3. Fish tank mixed with fish
Too high density aquaculture produces more pollution sources, and the water quality is difficult to maintain. It is easy to cause scales to rot (especially when mixed with rays). The hair color of single culture is more stable than that of excessive mixed culture. Because it involves the strength of fish, miscellaneous fish should not be bigger than arowana, nor stronger than arowana.
Second, the lights:
Arowana is colored by light, and it is impossible to color without light. When people wholeheartedly pursue the thick-colored arowana covered with gills in magazines, they can know that the breeding environment of these arowana is full of light for coloring. Pursue thick hair color, just to give enough light. Lighting is the fastest, but be careful to drop your eyes. When arowana swims, adjust the light source position as soon as possible. Taiwan Province Province is the only country in the world, and the mainland attaches great importance to eye drops. In the origin of arowana, as well as Japan, South Korea and other importing countries in Southeast Asia, color, body shape and posture are all concerned. An arowana with excellent body shape and thick coat color is extremely precious and expensive, and eye drops can't cover up its defects. Of course, an adult fish with no defects and red color is very rare and precious, but few people can show it. )
The choice of lamp tube is still popular from the point of view of individual and origin.
Third, water:
The water quality is stable, and the fluctuation of PH value is small. The low conductivity below 0.300 can make the coat color of arowana continuously colored. In order to maintain good water quality, there must be a perfect denitrification filtration system. A perfect and powerful nitrification system can reduce the time limit for changing water. Shortening the time limit of water change can reduce the fluctuation of PH value affected by each water change. Improving the nitrification system as soon as possible is the fastest way. But it is necessary to clean the bottom sand regularly. Although there are many substitutes for filter materials. Things with a single unit price are easy to use. But when you can't cultivate enough nitrifying bacteria, please use high-priced filter materials and commercially available digestive bacteria to quickly keep the water quality of the fish tank stable. When the fish tank is gradually balanced and you know the water quality to a certain extent, you can change it slowly or find other substitutes. Giving fish good water quality is just like people need clean air.
How to judge the good water quality? Water looks very transparent and bright. There are no fine suspended solids, bubbles and oil stains on the water surface. Bubbles will burst when they hit the water. There are no bubbles gathering. ..
1. Water temperature:
Keep the water exchange temperature at +/-2 degrees to avoid violent vibration. Dragons below 20CM maintain a high temperature of 30~3 1 and promote new metabolism. Xiaolong is easy to scale, and Dalong can accept the temperature of about 28 degrees. Experiments show that the best hair color of Dalong is 25 degrees. But it is very susceptible to water mold. The premise is that the wattage of the heating rod is enough. It's too late to stop the temperature from dropping rapidly. Arowana can survive at 18~35 degrees, but rapid temperature shock is very dangerous. High temperature to low temperature is acceptable, and low temperature to high temperature will lead to sudden death.
2. Black water:
There are many brands of blackwater in the market, and their composition is unknown. You need to choose carefully. Choosing foreign brands is more secure. Black water can be discharged or not. The release time is also important. Through experiments, not every red dragon with different coat colors is suitable for releasing black water. The purpose of black water is to stabilize arowana and improve the original water quality and color. Good black water will not affect the transparency of water, change the color of water but keep it transparent. There are no impurities and bubbles on the water surface, and it will not stay overnight.
When do I need to add black water?
Fading after long-distance transportation. Weakness after illness. When the color needs to be accelerated. When Xiaolong is in a hurry.
The mentality of raising arowana:
Without human negligence, the life span of a dragon fish is 10~ 15. The real beauty of arowana is at the age of 8, when it has completely changed color. Thick hair color and huge body size over 60cm will be very shocking. Isn't this what we saw in the previous book, and the hands of old players? Unfortunately, today's arowana lovers have no patience and work support. They blindly pursue high quality. High-priced arowana suddenly needs X work support and patience. It will be red in a year or two (arowana can't be red in eight years). Arowana accumulates color by time. The thicker the color layer, the closer it is to red) ~! ~
Before raising high-quality arowana, we should consider whether we can effectively control the above three points: environment, light, moisture and patience! In fact, no matter what kind of fish we raise, we should have a correct way to treat fish, that is, you should have enough patience! ...& gt& gt
How to raise arowana, the geomantic function of arowana
The geomantic significance of arowana.
Because arowana is like a dragon, it is regarded as the embodiment of the dragon. Arowana has the geomantic function of saving houses, exorcising evil spirits and making money.
Among Thais, arowana is raised and worshipped, praying to bring the rest.
In Indonesia, arowana can avoid losing money, breaking evil feng shui and other disasters.
Selection and placement of fish tanks.
As long as the width of the living room is a quarter, the shape of the fish tank should be square (except in special circumstances). Family fish tanks can be placed at the door to ward off evil spirits and brake; You can also put it in the living room, and your career is booming; Restaurants can also be used for family harmony; But don't put the fish tank in the bedroom. There is a term in Feng Shui called "shower head water". If you are affected by "sprinkling water on flowers" for a long time, you will easily get sick and your intelligence will decline. However, if you want to get angry, your head must be very close to the fish tank, that is, the person sitting next to you will make the problem of "shower head water". So you can keep the fish tank away from the sofa 1 meter and avoid the "bath water".
The number of three fish
According to the Book of Changes, the number of fish is 3, 6, 7, 9, 13, 17, 18,19,21.
According to the traditional geomantic omen, a piece of white water can make a fortune.
Erliang black soil can hold water, which is not conducive to wealth.
Three things-three green trees drain water, which is not good for wealth.
Four articles-four Lvmu, although drained, Siqing is a satellite, which is based on good luck.
The loess blocks water in the fifth five-year plan, which is not conducive to wealth.
Sixty-six white gold produces water, which is beneficial to wealth.
July 7th red gold begets water. Although it is a bad star, it is based on good luck.
Eight or eight white mud can make water, but eight white mud is the left auxiliary star and the lucky star.
Nine fires in nine purple, but right, as a lucky star, can prosper.
If more than ten articles are divided by integers, such as twenty articles, two articles are considered and fifteen articles are considered five.
According to each constellation,
Rats and pigs: 1 or 6
Snakes and horses: 2 or 7
Monkey, chicken: 4 or 9 or 5
Dragon, dog, cow and sheep: 5, 10, 4, 9
How to raise the red dragon
Multiple feeding and polyculture
Arowana is a very fierce fish. Under the same feeding condition, 2 ~ 3 fish will fight nonstop.
Once at a disadvantage, the weakest tail may be killed, so it is safest to raise it alone. However, if there is
Several arowana are swimming around in the big fish tank, which is a very attractive scenery. If it goes well, it may succeed.
. I once made ten tails swim together and successfully made a pair.
Although it is plural feeding (two or more arowana feeding methods), sometimes three will not quarrel, and sometimes five will.
I have been arguing; Although some people say that 10 will never quarrel, we should not take it lightly. The same is true
It depends on the ratio of fish to aquarium size. Suppose it is a fish about 20 cm, put five tails into 60 cm.
Feeding in a fish tank will have more or less scratches, but it doesn't matter; If you change to a 90 cm fish tank, most of them
There will be heated arguments.
Finally, some scales fall off and some fins disappear. Because the boss who consolidated the site appeared, in order to prevent
When other fish came into their sphere of influence, they began to fight. Instead, a 60 cm fish tank is narrow and empty.
Occasionally kill their energy, not a serious fight. If you are interested in complex breeding, please remember the numbers.
The relationship with the size of the fish can proceed smoothly. In addition, after more than two fish are put in, even if they fight.
Please wait patiently for a period of time, and they will naturally make up for it. As for the extent to which they can be tolerated.
It depends on the judgment of the owner.
I once put 20 individuals of 40-60 cm in a fish tank of 180 * 60 * 60 cm.
Feeding. This fish tank has been in a state of too dense fish, and there are small disputes from time to time. Most of the fish are on it.
Always hang a little color. Therefore, if the owner can't stand the harm of arowana and wants to keep it harmless, it is still only
You can eat alone.
Let's talk about mixed culture with other fish species! Every arowana has a different personality, some gentle, some.
Rough. The fish species suitable for polyculture are probably large fish such as rocket, platypus, tiger tiger and flying phoenix. These fish
Instead, it is unexpectedly suitable for mixing with arowana. Of course, I suggest more polyculture. Face a dragon
Fish, 1-2 Different kinds of fish are very dangerous, even if they live in peace for two or three days, they can't be ignored because
Maybe in another day, other species may have been badly bitten.
I once put 55 cm arowana with walrus close to 1 m, and the walrus close to 1 m was the next day.
I was bitten black and blue. Personally, I think arowana is invincible in the world and is the most powerful fish. Remember, after swimming,
Must be observed for a period of time.
Fish tank size
Regarding the size of the fish tank, arowana is a large fish, and the wild individuals can reach 1 meter. Used to be in Taiwan Province province.
The aquarium saw an 80 cm orange dragon. There is only a 300 * 100 * 60 cm fish tank. while
Sometimes I think it's really huge, which makes me want to see the arowana 1 meter long.

The aquarium saw an 80 cm orange dragon. There is only a 300 * 100 * 60 cm fish tank. while
Sometimes I think it's really huge, which makes me want to see the arowana 1 meter long.
Anyway, it is enough to raise 15-20 cm young fish in a commercially available 60 cm fish tank. only
There is no doubt that the depth of the fish tank exceeds its length. Once you are 30 cm long, you should prepare at least 90.
* 45 * 45cm fish tank. However, a 90 cm fish tank, soon after two years, some arowana will have a length.
It will be more than 50 cm, and you need a 60 cm deep fish tank. And a fish tank with a length of 120 cm,
It's a little unfair to fish. If possible, it is best to prepare a fish tank with the size of 150 cm.
Why does the depth of the fish tank have to exceed the length of the fish? Because a fish tank smaller than a small fish will bring a lot
Trouble, the most common situation is to turn your cheeks. The reason of gill turnover comes from pressure, and the drastic change or deterioration of water quality will also occur.
This phenomenon often happens. However, the most common case of branchial inversion is living in a small fish tank for a long time.
The fish body is not easy to rotate, causing psychological stress. Fish must be bent and shortened by rubbing against glass. Tail fin is also because
Friction and damage. Even if the fish's coat color is beautiful and its posture is flawed, the value of arowana will be greatly reduced.
In short, the bigger the fish tank, the better. I believe this will show you the swimming style of arowana.
About water quality
Arowana can live in a wide area between weak acidity and weak alkalinity. However, put the bought arowana into yourself.

Arowana feeding and food?
Arowana is a carnivorous animal, and frogs, loaches, crickets, goldfish, grasshoppers and shrimps can all be used as feed for arowana. We all know that feeding red arrow or shrimp will improve the color of red dragon, because both red arrow and shrimp contain red pigment. However, in the Arowana and Yachenglong stages, it is best to give up (or use less) food rich in shrimp lycopene and try to feed it with high-protein food (frogs, small fish, breadworms), so that the fish will grow faster and will not induce the growth of red coat color. The coat color of red dragon is very long. Generally speaking, Jackie Chan, who is five years old, has a relatively fixed body color.
Other feeding methods of arowana:
Water quality. Generally speaking, the owner will deliberately adjust the water quality to pH6.5, which is suitable for the origin of arowana, but arowana is a very good fish. As long as the pH value does not fluctuate too much, fish can live well between 6 and 8. But the problem is that weak acidic soft water will promote the hair color of red dragon. The thicker the hair color, the more serious the situation of eating boxes. So you can choose hard water with pH8.0 to raise arowana. Water with high pH value and hardness is helpful to the development of blue background, so it will naturally have fine frame performance when it is helpful to the development of blue background and inhibits red hair color.
Light. Some people choose plant lights or sunlight to attract color in arowana culture, but this way of attracting color can make fish without heavy background color become redder; Fang. In order to cultivate thin-framed fish, we should give up using sun lamp or plant lamp in the stage of small arowana and Yalong, and use blue tube as bait to deepen the background color of red dragon; Wait until the background color of the fish is set (fish is about one and a half to two years old) and then start to attract red (food lighting), so it will be red, red and blue. It is best for arowana to choose sunlight, because long-term use of light will darken the back of arowana.
How does arowana turn red?
Arowana should be kept beautiful and red. The following three feeding methods are very important.
I. Environment:
The red dragon changes its coat color with the environment, which is the so-called environmental protection color.
1. fish tank: The tested black cylinder is red, the blue cylinder is bright, the white cylinder is transparent, but the red is light.
2. Fish tank position: Arowana is unstable next to the moving line that people often walk, which affects hair color; In secluded corners and basements, arowana is relatively stable and has excellent coat color.
3, fish tank mixed fish culture: too high breeding density is relatively more pollution sources, water quality is difficult to maintain. It is easy to cause scales to rot (especially mixed culture with radiation), and the hair color of single culture is more stable than that of excessive mixed culture. Because it involves the strength of fish, miscellaneous fish should not be bigger than arowana, nor stronger than arowana.
Second, the lights:
Arowana is colored by light, and it is impossible to color without light. When people wholeheartedly pursue the thick-colored arowana covered with gills in magazines, they can know that the breeding environment of these arowana is full of light for coloring. Pursue thick hair color, just to give enough light. Lighting is the fastest, but be careful to drop your eyes. When arowana swims, adjust the light source position as soon as possible. (
Taiwan Province Province is the only province in the world, and the mainland attaches great importance to it. It can't control the origin and South-East Asian Arowana importing countries such as Japan and South Korea.
What matters is color, shape and posture. An excellent arowana with good posture and thick coat color is extremely precious and expensive, but it is eye-catching.
Defects don't hide Yu. Of course, a flawless red adult fish is very rare and precious, but how many can you find?
This performance. ) The choice of lamps, from the point of view of individuals and places of origin, luminous plant lamps are still more popular.
Third, water:
Water quality is stable. A small fluctuation of PH value and low conductivity below 300 can make the coat color of arowana continue to be colored and maintain good water quality. It is necessary to have a perfect filtration system for peroxynitration. Perfect and powerful nitrification system can reduce the time limit of water change, and reducing the time limit of water change can reduce the fluctuation of PH value caused by each water change. In order to improve the nitrification system as soon as possible, laying bottom sand is the fastest method, but it needs to be cleaned regularly. Although there are many substitutes for filter materials, it is not necessary to have something with high unit price. Can help to quickly maintain the stability of fish tank water quality. When the ecology of the fish tank is gradually balanced and the water quality is known to a certain extent, you can change it slowly or find other substitutes. Giving fish good water quality is just like people need clean air.
How long does it take to raise arowana to change water?
1. The water to be lifted should be large enough. The cylinder is larger than 1 m2, of course, the larger the better.
2. The water quality is stable. Raise the water first, and then use real fish to break the tank, for example, use Qinglong or Star Dragon to break the tank. /kloc-after 0/month (must be disease-free), you can consider letting fish enter the red dragon. If there is an elemene leaf, you can use one leaf in every 100L of water and put it at the end of the filter outlet.
3. Quarantine and isolate the new fish before entering the aquarium. Prepare an isolation cabin. The size of the quarantine pond is subject to the size of the red dragon. For example, a 25CM dragon can use a water tank with about 60L water, plus physical filtration and oxygenation equipment (oxygenation pump). When the red dragon comes back, he should soak in water first, that is, soak in the bag for 30 minutes, and then add 1 water to the bag every 30 minutes, ***3 times. Then enter the isolation cabin. Observe whether there are obvious symptoms in the first two days, and if not, carry out routine insecticidal sterilization. After 4 weeks, after the quarantine, you can enter the feeding tank for feeding.
4. Water temperature and quality. The water temperature is 23-28 degrees, and Honglong likes weak acid water.
5. bait. It is best to have artificial compound feed, if not, use Eupolyphaga sinensis and centipede. Or use quick-frozen shrimp (cut shrimp bones).
6. Daily management. Baiting should be qualitative, quantitative and timed. Don't be too full. Change 1 fresh water every week.
7. others. You'd better buy two heating rods. Even if one of them is broken, the other can barely support it, so that the water temperature will not drop too fast. Filter enough, because the red dragon is a big fish that can eat and pull, and strong filtration can maintain water quality. Avoid eating live small fish, because small fish may carry germs and easily cause arowana to get sick.
What should I pay attention to when raising arowana?
There are many things to pay attention to, for example, when raising young fish in a black tank, you should not be hungry, otherwise it will be easy to get into your mouth. The cylinder should be big enough, with a minimum of one meter, eight widths, 70 heights and more than 65 heights. The bigger the better. The background needs black light, that is, ordinary LED red light can't be mixed with other bigger fish. In terms of feeding, frozen river shrimps are the main ones. When they grow up, they won't be so troublesome. They should adapt to soft water with a PH of 4.5-8.
