anybody know what kind of coral this is? Got it from a friend with the tank and he didn't remember what it was. It is starting to look sick and I am getting a bit worried about it the tank has been set up for several years, I have had it a couple weeks. The temp is 79 salinity is 1.024, ph 8.2, nitrite 0, nitrate 0-10, ammonia not detectable. He has started getting a film on the top of him and the "stem" is more yellow than what I remember.
