Hey guys, I wanted get your opinions on what this could be on my Pink Hammer Coral. I've had this coral for about 3 months and it has been happy until the last few days. Three of the four heads still extend, but none of them seem extremely happy. I noticed today some white disc looking growths on the head that does not extend. Is this the skeleton, or some kind of parasite? Any ideas? My lights were starting to ramp down, so the polyp extension on the other 3 heads is less than what they normally are. All of my other corals are happy and healthy. Let me know what other information you may need to diagnose.
