There are several kinds of Arowana, and explain in detail, it is better to have pictures

According to the arowanaThe black dragon watches the fishThe distribution can be roughly divided into the following categoriesThe black dragon watches the fish:

AsiaThe black dragon watches the fishRed Dragon, Golden Dragon with back, Golden Dragon with Red tail, Azure Dragon

AmericaThe black dragon watches the fishSilver belt, black belt, walrus

Australia: Pearl Dragon, Star Pearl Dragon

Africa: black Dragon

[red Dragon] has bright red marks on its cheek cover, and the colors of fish scales are red, orange, crimson, blood red, etc. Generally speaking, the color of No. 1 red dragon is red, which can be divided into pepper red dragon and blood red dragon, while No. 2 red color is orange.

At present, the price of Asian Arowana is the highest. The hot golden dragon has golden scales all over its body, not only that, but also the color of gold will deepen with the increase of fish age. Gold on the back has several different background colors, but most of them are purple. Other rarer ones are blue, green and gold.

[red-tailed golden dragon] the red-tailed golden dragon is characterized by dark green on the back of the fish and brown on the upper part of the dorsal and caudal fins. The scale frame is shining golden yellow, and the golden color of a good golden dragon will even reach 1par 2 of the scale. There is no red imprint in the operculum, but it is completely bright golden yellow.

[Azure Dragon] the scales are cyan, the fins and body color are bluish yellow, the body is smaller than other arowana, and the lateral line is particularly obvious. Good Azure Dragon's upper body will have a touch of blue or purple, if not, it is the cheapest kind of arowana. The head of adult fish is also rounder and smaller.

[silver belt] its body is flat and long, the head is big and the tail is small, it has a pair of long dragon whiskers and big eyes, the body color is silver, the dorsal fin end is slightly pink, and its body length can be up to 100 centimeters. it is the mildest species of arowana.

The size of the black belt is similar to that of the silver belt, except that when the fish is young, the body is slightly black, and when it grows up, the black gradually fades, the scales turn silver, and the fins turn dark blue. When they are very large, they tend to be black, purplish and cyan. This kind of fish is easily frightened, and its physique is weak, so it needs careful care.

[walrus] the fish can grow up to 5 meters and weigh up to 400 kilograms. It is generally difficult to raise in an aquarium and is eaten as meat by indigenous people in Brazil. This fish is not similar to arowana, its body color is black, chubby, thick scales, head like tiger head, hard, when young, the body is dark green, caudal fin black, when growing up, the scales will have red scale frame; this fish does not have whiskers, growth compared with the general arowana, the growth situation is fast, a year weight up to 3 to 5 kilograms, rapid reproduction, 4 fish at the age of 5 can lay eggs, the number of more than one hundred thousand. With an egg diameter of 1.8 centimeters, this fish is very popular in Japan because it is a giant among freshwater fish.

Pearl dragon, also known as Australian dragon, is small in size, narrow in width, short and unstiff beard, light brown, golden yellow or grayish green in color, caudal fin, dorsal fin and anal fin with golden markings and scales with silver in yellow. the body length is about 50-70 cm. Pearl dragon is a very strong one, the character is the most ferocious, very aggressive, not suitable for mixed culture.

The star pearl dragon has a slender body, dark brown and green olive on the back, silver on the side, one or two small red spots in the center of the silver-white scale, red spots on the fin, and a very short beard. The average body length can reach 50 cm to 60 cm, with a maximum of 90 cm. Bad temper, mixed breeding is not easy.

[black dragon] is the largest known freshwater fish species, with a body length of more than 3 meters, and the longest on record is 15 meters. The body color of male fish will be red from the tail scales to 2 inch 3 as they grow, while the body color of females will be black. African black dragon is relatively flat and round, thick head, special is toothless, and using the tongue to eat, can also be eaten by the Gill, that is, filtered by the Gill, through the secretion of mucus adsorption of microorganisms or plankton into the back, is its peculiarity. Adult fish can grow to about 1 meter, weigh up to 6 kilograms, and the egg diameter is about 1 centimeter. This fish is good at jumping, so the aquarium should be covered with glass to avoid jumping out.

What's the Dragon Fish like?

In the ornamental fish marketThe black dragon watches the fishThere is a kind of tropical ornamental fish called arowana which is the most exquisite.The black dragon watches the fishIt swims in the clear water with a unique figure and elegant posture. It is not only a rare top grade among ornamental fish, but also the most popular and fashionable ornamental fish species in Asia.

It is said that the arowana shines like a dream, and its scales are particularly large. When illuminated by light, it reflects a pink glow, which other ornamental fish do not have. Therefore, arowana has a very high feeding and ornamental value. In Southeast Asia, Hong Kong, Macao and Taiwan, and places where overseas Chinese are concentrated, arowana has always been regarded as a sacred fish and can be regarded as fengshui fish to ward off evil spirits in Wangjia Town. Among them, the red arowana, which is on the verge of extinction, has been listed as a Class A protected animal and has a noble price. In Hong Kong, Macao and Taiwan, the price of a red arowana is more than one million yuan, which has become a symbol of family wealth and status.

According to relevant records, arowana is a very old large tropical ornamental fish, which belongs to the ancient fish osteoglossus family, with weak reproductive ability, and the hatching and rearing of young fish are very peculiar, usually female fish spawn and male fish hatched and nurtured in the mouth. Because of the two beards on its mouth, the shining large scales and its ancient life history, people naturally associate it with the dragon in Chinese legend, so it is called "dragon fish". And Arowana Farming is also seen as people's blessing, prosperity, wealth and longing. However, arowana has different names in different regions, such as "dragon fish" in mainland China, "dragon spitting beads" in Hong Kong, "silver belt" in Taiwan, and "silver boat broadsword" in Japan.

Arowana is produced in Asia, South America, Australia and Africa. The main species include Red Dragon, Orange Red Dragon, Platinum Dragon, over-backed Golden Dragon, Red-tailed Golden Dragon and Azure Dragon from Southeast Asia, Indonesia, Malaysia and Thailand, as well as Silver Dragon, Black Dragon, Walrus and Star Dragon from Africa, South America and Australia. Generally speaking, Australian star dragon, also known as Australian star dragon, body length 40 to 50 cm, strong adaptability to water quality, easy to raise, low price, but not many breeders; Azure Dragon, also known as green golden dragon, 60 cm long, strong physique, not strict on Water quality; silver dragon body length 1 meter, low price, easy to raise; black dragon body length about 1 meter, high price, not easy to raise The golden dragon, also known as the yellow-tailed golden dragon, has a body length of about 60 centimeters, with a high ornamental and price; the red-tailed golden dragon is about 69 centimeters long, the fish is beautiful, and the price is high. The price of each young fish, which is only 10 centimeters to 12 centimeters long, is more than 1000 yuan. The Red Dragon, which is listed as a world class A protected animal with a body length of about 60 centimeters, is currently the most expensive species of freshwater ornamental fish, on a par with China's giant pandas. It is understood that silver arowana and golden arowana are generally popular in China, among which the red dragon and over-backed golden dragon are valuable species.

"the real watching arowana is not as simple as looking at it with your eyes." Probably because of the high price of arowana, there are not many aquarium shops selling arowana in the viewing fish area of Laitai Flower Trading Center, but if you can bear it, it is not difficult to pick a few satisfactory arowana. The owner of one of the aquarium stores selling arowana told reporters that to see the arowana, you should first look at the tentacles. Tentacles are very important to arowana. Good arowana tentacles are straight and the color is the same as the fish body, followed by eyeballs. A good arowana eyeball should be large and protruding like a searchlight and rotate flexibly; in addition, the epidermis on the top of the arowana head should be as smooth and smooth as possible without wrinkles; and the upper and lower lips should be closed. If the lower jaw protrudes or has a tumor-like protuberance, it cannot be said to be a good mouth shape, but also pay attention to the color of the upper and lower lips and whether it is consistent with the color of the fish. In addition, the arowana's scales are large and neat, looking very shiny, but if there are spots, the arowana's cheeks should be neat and shiny, not sunken, and the cheek rake cannot be curled; the arowana's pectoral fin is like a dragon claw, which is a symbol of the arowana's power, so it should be extended and neat as far as possible, and the fin should be shaped like a circular arc. On the other hand, the fins of the anal fin, dorsal fin and caudal fin are required to be extended straight, the caudal fin should be large, and the fin will not shrink when turning. "basically, after paying attention to these aspects, we can choose and buy a relatively good arowana."

However, as there are quite many kinds of arowana and the prices vary widely, the amount of money budgeted is the first condition for the purchase of arowana. For example, it is impossible to buy a No. 1 red dragon for the money of a red-tailed golden dragon. At the same time, it is best to buy arowana with a length of more than 25 centimeters, because the beauty and ugliness of arowana are easier to distinguish at this stage, and it is generally not easy to get it wrong.

Arowana live near the surface of the water and rarely dive to the bottom. Width is the first consideration in the aquarium where arowana is raised. If the width of the aquarium is not wide enough, it will cause arowana spine bending, eyeball prolapse, Gill roll and so on!

The aquarium had better be placed in a place where the light is proper, the air is well ventilated and the noise is avoided. The aquarium should be stable, easy to observe and easy to change water.

The aquarium for breeding arowana should be at least 120cm × 50cm × 50cm (length × width × height). Of course, the best aquarium is 150cm × 60cm × 60cm and above! When Feeding arowana, it is best to put it in a large aquarium at the beginning to avoid frequent tank changes, which can easily hurt arowana.

2. filtration system (key)

Arowana is a carnivorous fish with a large body, and a large amount of its excrement can easily sink into the bottom sand. If the bottom filter design you use is unreasonable, the bottom sand may become a "dung pit" and become a hotbed for bacteria, no matter how you change the water!

Feeding arowana is recommended to use two out-of-tank filter buckets to form a water vortex in the fish tank, and then add a submerged motor inlet to the water vortex. In this way, feces and residual bait can be easily inhaled into the filter, or the use of an out-of-tank filter bucket and an upper filter can achieve the same effect. At the same time, the use of these currents can also form a proper flow of water in the fish tank, which can help the dragon fish to move, and can replace the wave motor when the current is large and the fish tank is small!

At the same time, it is necessary to establish perfect biological and biochemical filtration to achieve ecological balance. It is best to use some chemical adsorption filter materials such as activated carbon and zeolite in the system. it should be noted that this kind of filter material only has a useful life of 2-3 months and must be replaced when it expires.

III. Lighting equipment

When raising arowana in a fish tank, it is best to use lighting equipment, with the light can observe the arowana "seek a smile", but also can promote the arowana color and metabolism! Halogen lamps and superlights are recommended to achieve the effect of natural light.

4. Temperature control equipment

The water temperature of rearing arowana is between 24 and 29 ℃ (preferably between 26 and 28 ℃). Although the arowana can adapt to the harsh environment, it will also produce uncomfortable symptoms if the water temperature changes too much. Therefore, a set of high-quality temperature control equipment is essential! As the arowana is large and powerful, do not use glass heating rods, you can use quartz or stainless steel! It is best to use two heating rods. When one fails, there is a spare one so that the temperature in the cylinder will not drop too fast!

5. Oxygen enrichment equipment

The function of the aerator is to increase the oxygen content in the fish tank. Due to the large oxygen consumption of the arowana, the oxygen equipment is particularly important in the arowana tank.

VI. Water quality control

PH: arowana prefers 6.5 to 7.5 weakly acidic medium-sized water.

As for the cycle of changing water, in order to take into account the efficiency of the filtration system, the size and quantity of fish, it is recommended that the water should be changed regularly once a week, and the amount of water change should be 1 pound, 3 pounds, 1 pound, 4 of the total amount of water in the fish tank.
