Purple vilida
 

Hey guys
Gotta question, I got a purple vilida and a bonsai coral that are not too happy in the tank. They have lost the intense color they once had and are brownish now. I have read that is caused by not enough light. All other corals are doing great just these two. Any suggestions? I moved them higher up as well to give them more intensity of light but no luck yet.

Check your parameters if you think your lighting is good.

How long have them been in your tank? What kind of lighting do you have? Are they showing polyp extension? Is the coral lightening or darkening brown? Could be a huge range of issues or something as simple as too much nutrients in the water. Try running some tests to get a better idea of whats occurring.
