There is a domineering name, majestic posture, large scales, bulging eyes, tail fin stretched and flowing, it is the representative species of Chinese goldfish - dragon goldfish.
Goldfish is our national treasure, there are many varieties, if carefully combed, you can turn the entire strain into a big tree. Grass goldfish are like tree roots, dragon goldfish are trunks, and wen and egg species are leafy.
Today's focus is on the dragon species goldfish, talk about its past and present lives, let us better understand it, watch it, and protect it.
1. Origins.
Around the middle of the fifteenth century, players often found that individuals with fish eyes protruding from individual species were just one eye, and were initially discarded as inferior species.
Until 1592 (year of the dragon), a player in Guangzhou found two fish eyes protruding at the same time, the chinese goldfish, at that time some people said that it was tianlong xiafan, a pair of protruding fish eyes is the "dragon's eyes", so it was retained as a kind of fish.
After hundreds of years of careful cultivation, more and more varieties of goldfish protrude from the eyes have emerged, and huge strains such as red dragon, ink dragon, purple dragon, butterfly tail, five flowers, and panda have gradually emerged.
2. Viewing.
Compared with the simple and primitive grass gold, the modesty of the literary species, the clumsiness and weakness of the egg species, the stretched shape of the dragon goldfish, the atmospheric appearance, and the domineering when swimming, it is indeed qualified to represent the authenticity of the Chinese goldfish.
Since the goldfish became an ornamental fish species, it has always been the best overhead effect, and with the popularity of glass fish tanks, people no longer simply pursue the overhead effect, but a full range of viewing. Compared with other goldfish species, the dragon goldfish has won a complete victory in this regard and is sought after by more aquarists.
In particular, foreign goldfish players take the dragon species goldfish as the main goal, believing that only the dragon species can represent the Chinese goldfish.
3. Breeding.
Given the many excellent qualities of the dragon goldfish, it is suitable for rearing in glass fish tanks and also for potting. In terms of water quality requirements, in addition to grass gold, it is the dragon species goldfish.
Do not think that it is resistant to breeding on the skin to relax the care of the fish tank, glass fish tank is generally equipped with the corresponding filtration equipment, as long as the normal operation of the general problem is not big. The pot culture should be cautious, the current ceramic fish pot design is relatively simple, generally there is a water pump, some have nothing.
Raise goldfish in the porcelain pot to work harder, if you do not bring a water pump, you must install one, for the sake of aesthetics, you can place a rockery on the side of the pot, hide the pump inside, and plant some plants on the stone, which is both beautiful and can help purify water.
If there is a water pump originally, it is also necessary to place the filter media in the place where the water flows, and in order to facilitate hiding and later cleaning, use filter cotton or biochemical cotton. If there is a water pump, there is no need for an oxygenated pump, and the appearance of a plastic pipe in the porcelain basin is indeed an obstacle to the view.
You can also place potted aquatic grass in the center of the pot to remove harmful substances such as ammonia nitrogen and nitrite, and aquatic grass varieties should be selected that should not be eaten, otherwise they will be bitten by goldfish after a few days.
A pair of dragon eyes is really cute, but it will also become a burden to them, and it is easy to bite the eyes when raised with other species of goldfish, so it is best to keep them alone.
4. About the classification of goldfish.
Japan has introduced goldfish from China since the Ming Dynasty, and after years of breeding, it has gradually been divided into three categories: hejin, gilded and lanshou. Because they are ahead of us in the ornamental fish trade, their classification is more recognized internationally, and their classification is grass, literature and egg relative to our classification.
At present, many so-called experts have proposed to integrate with international standards and merge dragon species with language species to facilitate our export trade.
I strongly disagree here, and we must not let this domineering name disappear, you say?
