Brother, is the arowana easy to raise? Where can I buy this kind of fish? How much are these French fries? Thank you.

It is suggested to go to "58 City" to find out the price of arowana and the information of fish farm, which contains the sales and breeding information of arowana, and it is the latest quotation of your city, and also the place for fish fans to exchange. Choose your city first, taking Chengdu as an example. Chengdu 58 city? 0? 3 Chengdu flowers, birds, fish and insects? 0? 30% flowers, birds, fish and insects? 0? 3 Shuangqiaozi flowers, birds, fish, insects and arowana are difficult to feed! It's hard to raise. Arowana is divided into Chili red dragon, blood red dragon and orange red dragon, and there are grades. The higher the grade, the more expensive the price, with Chili red dragon as the best. The same size as a red dragon. The scales, snout, gill cover, fins and tail of fish are all red to varying degrees. The subdivision is orange, pink, crimson and blood red.

Jiaohonglong has bright red gills and scales, mainly with bright red outer edges. All the fins are red and the snout is red. If the lights are turned off (because the lights in the fish tank have a red wavelength, the color of the fish body is not completely true when the lights are turned on), the scales are blue-purple, the lips of the fish are upturned when they are young, and the fins of the fish are red when they are adults.

Because the red dragon is a protected animal and its import is restricted, it is not so easy to buy a good arowana. Even if you have money, you may buy other arowana (such as orange dragon), because it was similar when you were a child (the color of arowana changed from small to large, but it did not change when you were a child). Some poor aquarium shops and even some bosses don't understand it at all, so they regard No.2 or No.5 as 1.

In general, there is no red pepper dragon in the arowana in the aquarium, because it has been selected in the stage of large-scale merchants, so it is best to provide a way to buy better red dragons, preferably with red body color or red spots in the dragon period.

The body color of the blood-red dragon does not have the red scale frame like Chili red dragon red, and there is no obvious crimson gill print on the gill cover, but it is evenly distributed throughout the body, but the color is still mainly red.

The survival of arowana needs weak acid to neutral water quality, and the hardness needs soft water. The PH value is between 6.5 and 7.5, and the DH value is 3- 12. The water temperature is 24-28 degrees Celsius. The nitrite content and chlorine content are preferably zero.

New fish in the tank: when new fish just came back, the air pump in the fish tank had to run for at least 24 hours to completely eradicate chlorine in the water. If the biofilter is used all the time, it is best to make the water reach PH 6-7 and the water temperature is 25 degrees Celsius. Add a small amount of salt (about 1 or 2 teaspoons in every 5 gallons or 20 liters of water) to the fish tank to reduce the risk of fungal attack, make the fish healthy and stimulate the appetite. If possible, it is best to take the water from the original tank of the new fish back to its aquarium (if there is no problem with the water in the original tank), and it is best to take it back to 1/3, which is conducive to the adverse reaction of the new fish to environmental mutation. It is recommended to raise arowana from an early age.

Daily management: change the water at least 20%-30% every week, and the ammonia content shall not exceed 0. 1 ppm (mg/ 1). Don't let the temperature and pH suddenly change, if the change suddenly leads to sudden death of arowana. Check the PH value and other toxic substances every week to avoid countermeasures. Be careful when changing water, so as not to scare arowana. Moreover, keeping arowana must avoid completely changing to new water, otherwise it will cause harm to the fish. If you see the fins and scales of arowana fall off, it is caused by too much water change. You can stop changing the water, and they will recover naturally. However, the amount of water exchanged should not be too small. Too little will make the fins opaque and the eyeballs turbid, leading to gills turning over.

Size of fish tank: As arowana is a large fish, the fish tank is at least 1.5m long, 0.5m wide and 0.7m high. The fish tank must be covered. Arowana belongs to the upstream fish and likes to jump, so as to avoid choking when no one jumps out of the tank.

Light: Arowana needs a lot of light, and it is best to have 4 hours of light every day. Other arowana also had better reach 8 hours of light. Some people who love fish, such as those who keep red fish, like to irradiate red fish with red light to achieve better results. The best light for arowana is daylight. Long-term use of light will darken the back of arowana.

Filtration: The young arowana is too big to be put in the grass box. As big as a fish tank, the problem of filtration is more prominent. The filtration systems suitable for arowana culture mainly include upper filter, outer filter, upper+sand pumping filter and overflow filter. However, it should be noted that when arranging the arowana box, you should consider arranging a water pump (surf pump), which has great benefits: first, it can form a strong water flow; Secondly, it can increase dissolved oxygen in water; Third, more importantly, arowana can keep a certain amount of exercise and keep the graceful figure of the fish; Fourth, it is also very important to avoid arowana turning over its cheeks, so that it can be trimmed and restored when it happens.

Feeding of arowana: if arowana eats too hard, it will bump into a certain angle in the tank, resulting in injury. It is best to feed in the middle of the fish tank when feeding. Arowana is a carnivore, and its recipes are mostly frogs, loaches, crickets, goldfish, grasshoppers and shrimps. There is a problem of adding color in breeding, such as red dragon. Feeding red arrow or shrimp will add color to the red dragon, because both red arrow and shrimp contain red pigment. Young fish under 12 cm just started to eat raw bait, and they can be fed with palatable bait such as white bread worm and shrimp (the head and tail must be removed, and it is best to peel them into shrimp balls to avoid hard shell injury to the stomach) and blood worm. Eat less and eat more meals, four times a day. The arowana around 1.5 cm can be fed with normal breadworms and shrimps (shrimps should be removed from the shrimp sword), or with small fish around 1.5 cm. At this time, arowana grows rapidly and eats an amazing amount. The feeding times and the feeding amount can be appropriately increased. Arowana above 20 cm can be fed with larger bait such as fish, shrimp, loach and meat. You can also feed live baits such as various insects, which are arowana's favorite food, but be careful not to pollute these baits. In addition, the internal organs, especially the liver, are not suitable for feeding arowana, and too much fat will cause arowana disease. Goldfish is not a good bait in live bait. Studies have shown that almost all infectious diseases or parasites infected by arowana, which eats goldfish exclusively, are infected by goldfish when they are kept in small fish tanks. It is best to use beef with less fat as artificial bait. Of course, you can buy special bait for arowana if you have the conditions. However, arowana will be unaccustomed to artificial feed at first, and it needs artificial bait training.

Breeding density: If arowana with a body length of 20 cm is cultivated, an aquarium of 5 square meters can raise arowana of 65, 438+05, 65, 438+05, 40 and 200 square meters. Visible density should be reduced as much as possible.

Arowana can live for about 18 years, and their growth and maturity take a long time. Generally, it takes 6- 12 years for females and 5- 16 years for males (depending on your reproductive level). And not all arowana can breed in the aquarium like arowana. At present, the main varieties of arowana cultured in the aquarium are silver dragon, red dragon, Qinglong, Australian arowana and so on. Arowana, like cichlids, are both oral fish and natural mating fish. In nature, arowana will hatch eggs in its mouth when it breeds. After hatching, the male will look after the young. When the enemy attacks or is frightened, the parent fish will hold the larvae in their mouths until the danger passes. This will continue until the larvae can feed themselves. From 65438 to 0966, Mr. Miyata and Shiro Tanaka of Japan used hot spring water and self-designed steel refined concrete sink to complete the first aquarium culture of arowana. So far, they have a considerable number of breeding in the farms in Asu hot spring area. So how to breed arowana in an aquarium? First of all, arowana should breed in a wide water body, and a better breeding box is best in a sink of 200×90×60 or 250× 100×60 over 2 meters. Preparation of parent fish: because arowana has its own habit of pairing, it doesn't like people to match them artificially. Therefore, several young fish can be raised together and paired freely from an early age (5-7 years old). You can also put mature fish, one female and one male, on both sides of a large sink, separated by partitions, and holes must be made in the partitions to facilitate the flow of water on both sides. Fish will adapt to the environment here. When you find that arowana is in heat, you will pull open the partition. At this time, they will catch up with each other and then bite each other's fins, especially from the gluteal fin to the caudal fin. Arowana will be frightened and jump, or collide, and even cause beard to break and bleed. This kind of injury will not pose a threat to the life of arowana in a short time, so everyone should be patient. After a few days, if the two arowanas start to calm down and swim slowly, it means that the pairing is successful. If you are still struggling, it means that the matching is unsuccessful. You should check whether the matching fish is immature. Is there anything in the water that shouldn't be there? Then raise them separately and then pair them. Distinguish mature males from females: males generally like to show off in front of females. The most important thing is that the male fish is slender and the pectoral fin is very long and dark red. The abdomen of the female fish is full and swollen because of the eggs. The fallopian tubes of female fish protrude during spawning. The vas deferens of male fish are concave. These are all differences. Water quality management: pairs of arowana will be injured, so water quality management is extremely important in aquaculture.

1, pay attention to the feeding of bait, and the residual bait must be extracted in time.

2, found signs of illness should be immediately treated with medicated bath, and pay attention to prevent other fish infection. Because arowana is extremely sensitive to drugs, the dosage is much less than usual, which we will mention in the disease of arowana. Pay attention to changing water more than usual during the medicated bath.

3. Keep the PH value at 6.2-7.2 to prevent hyperacidity, and the water temperature is 26-28 degrees Celsius. When you do this, you see the close arowana couple together and stop at the bottom of the aquarium, which is their choice of spawning place. Find something to hide from the light. This will make it more secure and easier to lay eggs. Seeing the male fish put the eggs in his mouth, he can wait patiently for the young fish to hatch. When the male fish takes care of the eggs, the female fish will be there. After about 60 days, the fry will come in and out of the male's mouth. Father Fish will slowly release the little fish, showing great concern. This will last about 90 days. Little fish will go in and out of dad's mouth less. At this time, you can quietly fish out the small fish, and be patient when fishing, because other little guys will definitely hide in the fish father's mouth for a long time, so you can wait slowly. Male fish usually contain 40 eggs, but in the end there will only be a dozen small fish. It can be seen that the reproduction of arowana is really not easy. Parent fish will stop eating before spawning and will not eat until the young fish leave the male fish, so it is extremely harmful for the male fish to spawn and reproduce once. If the breeding before breeding is not good enough, the male fish will collapse and even die, so pay attention to the preparation before breeding. The experiment of artificial hatching of fish eggs has not progressed so far, and the male fish still has to work hard.
