Too much light in your aquarium makes your fish lose its color?

by Richard Back

Hello guys, Richard here again. As you may have noticed, I am very active on social media sites and I try to absorb all the information that I can from various people that I follow and respect. I also visit forums from time to time to discover new trends and find out what other hobbyists are trying these days, and I often come across some interesting piece of information or a question that really grabs my interest. This happened to me yesterday; allow me to share it with you. In a Korean reef club forum, I was informed that the high intensity of lights in our home aquarium will affect our fish’s (specifically anthias) colors.
This is something that I have never heard of before and I was immediately fascinated. I admit that I doubted the validity of this claim, as I have always thought that it was nutrition that affected the colors of the fish and that it had to be some very intense lighting to have a “tanning” effect on fish. Unable to solve this with my google ninja skills, I went on and asked some of the industry professionals to check out the validity of this claim.
