at night? Goldfish do not need lights at night. The reason is very simple. We raise goldfish at home, regardless of temperature, water quality, environment and illumination, all of which simulate the natural environment. In the environment where goldfish grow naturally, there is no light at night, so we need to follow the laws of nature and not turn on the lights. If the light is turned on all the time at night, it will cause the goldfish to be too tired and very easily frightened. If the goldfish can't get a good rest for a long time, it will lead to poor spirit, loss of appetite, and serious illness. So there is no need to turn on the light for goldfish at night without special circumstances.
at night? 1. When spawning: During the critical period of spawning and reproduction, goldfish need to turn on a nightlight at night, especially before the mother fish is isolated, it is better to observe their situation all the time and turn on the light at the right time.
2. When changing a large amount of water or medicine: At this time, the goldfish is relatively fragile, and it is most likely to suffer from hypoxia or poisoning at night. It is best to keep the light on all the time so that we can observe it at any time.
3, when just buying come home: The goldfish that just bought, if appear after turning off the light the phenomenon that startles jar, need to open a small night light to give it. Because it's possible that I was used to turning on the lights at the original owner's place. We can gradually reduce the brightness of the night light and relieve the symptoms in a week or so.
