Different varieties of goldfish choose different lights. When choosing lights, we should choose according to the background color of fish scales. The goldfish is divided into gold bottom and blue bottom. The fish with gold bottoms use yellow led lights to add color to their gold scales. Blue and white led lights are used for blue fish, which can not only increase the viewing effect, but also deepen the color of fish scales. In addition, it is better to use the ceiling lamp and the water lamp together when choosing the lamp, otherwise it will cause the fish to drop their eyes.
The background color used by goldfish in different periods is different. The black background is good for deepening the background color and gold quality of the fish, but it will affect their crawling back. The white background is very good for the fish to climb back, but it can not deepen the background color of the fish. The blue background combines the advantages of black and white, which can not only make the fish climb back, but also increase their background color. But that blue background plate can not be use for a long time.
When the fish's body length is only 15 cm, the white background board is usually used to help the fish climb back. When their body length reaches 27 centimeters, they need to change the white background and use the blue background board as the background. When the body length of the fish reaches 40 centimeters, they are almost adult. Adult goldfish temperament is strong, light-colored background board is not conducive to pacify the mood, need to change into a darker background board. It is recommended to change to a black bottom plate, which also helps to increase the gold texture of the fish body.
