how does arowana breed
arowana is one of the few surviving ancient fish. As far back as the Carboniferous, arowana belonging to Osteoglossidae began to exist. Later, the movement of the earth's crust gradually distributed arowana to all continents of the world, and now it is mainly distributed in Oceania, South America and Asia. Arowana belongs to the family Osteoglossidae, and there are several strains in different forms, among which the rare ones are arowana and arowana. Arowana is native to Malaysia, Arowana is mainly produced in Indonesia, and there are also Star Dragon (Pearl Dragon) produced in Australia and Silver Dragon and Black Dragon produced in Amazon River in South America.
Arowana can live for about 18 years, and their growth period and maturity take a long time. Generally, it takes 6-12 years for females and 5-16 years for males to reproduce. In nature, arowana will hatch its eggs in its mouth when it breeds. After hatching, the male fish will watch over the larvae. When the enemy attacks or is frightened, arowana will hold the larvae in its mouth until the danger passes. This will last until the larvae can feed on their own. At present, there are several varieties of arowana mainly bred in aquarium, such as silver dragon, red dragon, Qinglong and Australian arowana.
Before laying eggs, the two arowanas stopped eating, and the abdomen of the female fish began to increase a lot. At this time, the arowanas sometimes stick their tails tightly together, or lie close together on each other's backs. Sometimes the environment changes, Arowana is frightened and even eats all its eggs. Arowana spawning in aquariums is definitely different from spawning in natural rivers.
in the aquarium, it is necessary to keep a quiet environment and use lighting, about 8: -21: . The spawning time is during the day. The eggs laid by arowana are orange, with a diameter of 12-15mm, and fall from the fish like a marble with dazzling golden light. The amount of eggs laid is not much, and even less are hatched.
Arowana is an oral brood fish. When the female lays eggs, the male fish immediately puts them into the population. One male fish can put about 4-5 eggs a day. The female fish lays eggs, but the male fish can't contain so much. The female fish will immediately feel these eggs and begin to swallow them into the population, which is why the young fish hatched by Arowana are so few.
when the female fish feels that the male fish can't contain so many eggs, she will swallow the eggs in her mouth, which can protect them for about a few hours, and then she will eat them in her stomach. After the male fish put the eggs in his mouth, his mouth often wriggles or shakes the tap to balance his body. At this time, the female fish acts as a guard, and it will spread its pectoral fins horizontally to form a unique defensive posture.
Arowana lays eggs for females, while males hatch and females defend them. After about 6 days, the young fry will start to run in and out of the male fish's mouth, about 5-6 cm. This movement in and out will last from around 6 days after delivery to about 9 days. This kind of reproduction, arowana stopped eating for too long, consumed too much physical strength, and did great harm to arowana, but individual arowana could not recover and died. At present, China still relies on imports. In the natural waters of South America, a large number of sexually mature arowana nest and hatch arowana at the bottom of the river, which is very large.
what's the point of keeping arowana
1. The geomantic function of arowana
1. Arowana Wangcai generally believes that Jinlong, Red Dragon and Qinglong represent Liu Bei, Guan Yu and Zhang Fei, the three sworn brothers in Taoyuan respectively. Because Guan Yu is regarded as the God of Wealth and the Lu of Fu Lushou, the Red Dragon is also considered to have the function of prospering wealth and prospering the family. However, Guan Yu is also regarded as a warrior, so the red dragon also has a strong Shaqi, and some people who are in poor health or older are easily injured by Shaqi.
2. Arowana healthy and long-lived Jinlong is considered to be Liu Bei, and Liu Bei is the blessing of Fu Lushou. Raising Jinlong can be said to be a blessing. The dragon is Zhang Fei, and Zhang Fei is longevity. If you want to live longer, you can raise the dragon. And arowana has always had the function of blocking evil spirits and eliminating disasters, and it can bring good luck at home.
3. Arowana's five elements are different. Each of us has five elements, and there are also five elements at home. Among the varieties of arowana, golden dragon and black dragon represent water, golden dragon and silver dragon represent gold, red-tailed golden dragon represents earth, blood red dragon represents fire, and pearl dragon represents wood. You can apply the five-element pendulum method and cultivate arowana according to your own needs.
Second, the placement position of the arowana fish tank
1. According to the theory of five elements, the most unsuitable locations for placing the arowana fish tank are the middle and south, so placing them in these two positions will suppress the owner's fortune.
2. Different orientations have different functions, except for the three remaining locations in the south, which are suitable for placing fish tanks. Placement in the north can increase career opportunities, placement in the west can increase future generations, and placement in the east will make the owner healthy.
3. It is appropriate to put the fish tank next to the gate. Another suitable place to put it is next to the gate. The door is a channel to communicate the inner boundary of the house with the outside world, that is, the air port in Feng Shui, which is more important than the window.
4. Avoid placing arowana near the bed. It will make the owner have bad fortune, poor spirit and easy to have a headache. At the same time, it is not appropriate to put a fish tank at the end of the bed, because it is a crime to cut one's feet and water, and the owner's wealth is poor, and it is futile and hard to run around.
Third, matters needing attention in raising arowana feng shui
1. According to those people in birthdates who lack water in birthdates, putting fish tanks in the living room will be of great help to their luck; But those who avoid water, if they keep fish in the living room, are not suitable and easy to go bad luck.
How does Arowana distinguish between male and female
1. There is a difference between male and female Arowana, and the female has an A in the gills, and the tip is shorter than that of the male; However, the A word of male fish is not very regular, and the tip is longer. In addition, the head of the female fish is smaller, and the head of the male fish is larger because it contains fish eggs.
2. The male arowana of the same age is longer than the female. In general, the size of dragon tanks raised at home is mostly 18*6*9. In this environment, there is no obvious difference between the growth speed of female fish and male fish around 2cm, but the growth speed of female fish will obviously slow down around 35cm.
3. For the back-crossing arowana, the back-crossing speed of the male fish is faster, and the back-crossing degree of the female fish is not as great as that of the male fish. Generally speaking, almost all the six rows of bright backs are male fish.
4. The scales of male fish are nearly 8% gold, and 8% of pearl scales are bright, which is what we usually call "individuals with gold background"; Female fish are usually "blue-bottomed individuals", and about 5% of the beads are lit up.
