It is best to use tricolor fluorescent lamp as the special lamp for ornamental fish. When you see the colorful body colors of those fish species (arowana, arowana, arhat, parrot and gallnut), you should not just ask what you ate to make the fish have such a beautiful coat color. You are wrong. In fact, the coat color of fish is partly determined by genetic inheritance, and mostly depends on the influence of natural light sources on fish, that is, the selection and application of fish tank lights depends on the sunshine in the wild, and the use of aquarium lights is king. That's all you can say here Specifically, you will know it by Baidu.
That's my answer. I hope I can help you.
