I have a n orange plate coral in my Red Sea Max 250 -65 gallon aquarium. To me, it may be my imagination but the coral's orange color is not as vibrant and orange as before. I feed it oyster feast. I try to give it food but it does not seem to eat it. Does it look okay? Is there any advice that someone can give? I also attached a picture of two of one of my red Stoney corals.
