I have been noticing that my coral seems to be getting dark and darker around two of its mouths. I am wondering if my coral is infected or is just under stress. Is there anything I can do? Please help.
Given the extension you are seeing, it doesn't seem like there is necessarily a problem. How is your water chemistry? Any issues with any other coral in the tank?
