Dude - can you stick to one thread? You have started what, 4 now all asking about a sick and dying coral, but haven't given any of the additional info you've been asked for.
What is wrong with the coral? What are your water measurements? What kind of coral is it? How long have you had it? How long have you had the tank?
Either give some more info, or stop asking the same question because it appears like you don't actually want the answer!
firefish, ocellaris clown fish
caulastrea, green star polyps, palythoa, zoas
