Goldfish

Originally from China, also known as the "Golden Carp", similar to the carp (Cyprinus carpio) but it does not have mouth whiskers, is an ornamental fish from the evolution of crucian carp. There are many varieties of goldfish, with colors of red, orange, purple, blue, ink, silver and white, and five flowers, etc. They are divided into four strains, namely, Wen species, grass species, dragon species and egg species.

In the 12th century has begun the genetic research of goldfish domestication, after a long time cultivation, varieties continue to optimize, now the world's goldfish are directly or indirectly introduced by China.

Goldfish have a gentle temperament and generally live for about six years, but there are also longer ones. The goldfish is an omnivorous and partial carnivorous freshwater fish with well-developed pharyngeal teeth that allow it to swallow harder baits. Goldfish have a strong ability to adapt to the water temperature, but can not adapt to the drastic changes in temperature, its appropriate water temperature in the 18-26 ℃, the temperature is too high or too low will affect the goldfish feeding and growth and reproduction.

Goldfish like weakly alkaline water, and the pH value of the water body is more suitable at 7.5-8.0. When the water temperature starts to rise in the north of China during the transition between spring and summer, goldfish also enter the breeding period, and the water temperature during this period is controlled at about 20℃, which is more conducive to the spawning and hatching of goldfish.
