Goldfish have a strong ability to adapt to water temperature, but can not adapt to the drastic changes in temperature, its suitable water temperature is 18-26, too high or too low will affect the feeding and growth and reproduction of goldfish.

Goldfish prefer weakly alkaline water, and the pH value of the water body is more suitable. At the time of the transition of spring and summer in northern China, when the water temperature begins to rise, 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.

Its body is beautiful, there are many varieties, and its body is red, yellow, blue, purple, black, white, two-color, three-color, five-color and so on.

The color of goldfish is due to the production of many pigmented ** cells in the dermis, jujube pigment cells, and the color of some fish with the same body changes with the change of background within a certain range. The lack of nutrients in the feed, the dim light in the fish tank, and the high water temperature of more than 30 degrees may cause the goldfish to have a dull body color.
