The eyes of the Arowana are very developed, protruding beyond the orbit, with dorsal fins, fins and caudal fins, and the tail is dominated by double leaves. Because its prominent eyes resemble the legendary dragon, it was named "Dragon Eye". The body color is mostly red, red black and red and white, purple, variegated and so on.

The sides of the body are flattened and thick, and the abdomen is rounded. Due to the difference in the growing waters, the body color varies. It lives in shallow waters such as shallow river bends and lakes where aquatic grass is overgrown.
History: Since the discovery of red scaled fish in the Jin Dynasty, red and yellow golden crucian carp has begun to be discovered one after another. At the end of the Western Han Dynasty, Buddhism was introduced to China, and these rare colors and at that time seemed very mysterious golden crucian carp. In the Tang Dynasty, a large number of release ponds were built, the most representative of which was the release ponds in Jiaxing and Hangzhou. After the Southern Song Dynasty, goldfish began to enter the family, and the industry of selling golden crucian carp slowly appeared in the folk, which was called "fish work" at that time, and fish work gradually mastered the breeding method of golden crucian carp. During the Chongzhen Emperor's reign, it began to be uniformly called "goldfish". In the Qing Dynasty, the imperial palace and other dignitaries began to hire people to raise goldfish professionally, and these fish farming technicians were called "fish handles". Zhile, Zhile and Laishun Fish Shop were all famous goldfish shops at that time. In 1893, two new breeds were bred, the Ink Dragon Eye and the Lion's Head. In 1904, the goldfish bred three more species: the sky eye, the tiger head and the pompom. By 1935, there were more than 10 varieties of goldfish, mainly including dragon eye blister eyes, dragon eye balls, cinnabar eyes, pearl dragon eyes, blue egg balls and so on. From the end of the Qing Dynasty to the present, the appreciation and breeding of goldfish varieties have also become more meticulous, which has played a great role in the cultivation of excellent varieties, which is a milestone in the development of Goldfish in China.
According to the body color, longan can be divided into purple dragon eye, ink dragon eye, blue dragon eye, red dragon eye, five-flower dragon eye, white dragon eye, red and white flower dragon eye, cinnabar eye dragon eye, magpie flower dragon eye, purple and blue flower dragon eye, red head flower dragon qing and other strains. The mutated varieties can be divided into purple dragon eye ball, five-flower dragon eye ball, red dragon eye ball, four-ball dragon eye ball, blue dragon eye ball, ink dragon eye ball, red head dragon eye ball, dragon eye flipper gill, dragon eye ball flipper hat and so on. Its main feature is that the protruding eyeballs of the dragon eye have various shapes, including spherical, pear-shaped, cylindrical, grape-shaped, etc. About a month after hatching, the eyeball begins to protrude, and it is not obviously spherical after two to three months. Because the eyes of the arowana protrude to the sides, it has poor vision. Dragon eye fish are different according to the color, the color of the fish is different, can be divided into difficult to raise, easy to raise. The arowana is completely black after being dried from the eggs, and after a considerable period of time, it begins to change color. There are white, the first to appear, other colors due to the water exchange relationship, its discoloration will appear sooner or later. After the dragon eye fish changes color, it can identify the height of the species, and its eyes, body and tail are only necessary conditions.
The eyes of the dragon's eye are prominent, and the traditional dragon's eye has three types: abacus eye, apple eye, and bull horn eye. It can also be divided into three categories, ordinary dragon eyes, abacuses and living eyes. Ordinary dragon eyes, small eyes, abacus eyes large, and the living eye of the dragon eye is not fixed, will shake during swimming. And the eyes are large like "water chestnut flat", also known as "abacus" eyes. Only high and convex but not flat, and the cow's eye is the lower product of the dragon's eye.
The body shape of the dragon eye can be divided into: short hand type, long hand type and water drop shape. The dragon's eye of the short hand type is short and powerful, the long hand type of the dragon eye is thin and slender, and the teardrop-shaped dragon eye is fat, and the short hand type should be preferred.
The tail of the dragon's eye can be divided into three kinds: ordinary four tails, saucer tail and skirt tail, but there are also "unexpected surprises" with wide tails. Among them, the common four-tail is the most common, the disc tail is the breed selected among the four tails, and the skirt tail is mutated in the cultivation of the disc tail, because the tail of the skirt tail often droops after maturity and the yield is low. The broodstock of the saucer tail should be strong and powerful, the elasticity is not rigid, and a slight leaning forward or rolling up is a sign of a good disc tail.
