coral dying?
Forgive me in advance for my lack of terminology!
I got home last night and a coral in my tank looks horrible. All other corals are doing great all open extended and such. But this coral was shrunken and turned from yellow to a greenish color. It's usually fluffy and has a bunch of polyp (I don't even know if that's the word I am looking for) like things comin out of it. Nothing in the tank has changed, nothing new has been added. It is usually the size of a toonie and now it's between a nickle and a quater. Last edited by Flash; 05-09-2010 at 05:16 AM.

Hard to tell from the pic, but if that's a sarcophyton or leather coral, as long as your water parameters are good, it is normal behaviour for that type of coral. It sometimes will shrink and shed a protective mucous layer.
Make sure that you have alternating water flow around it and all other corals. That type of coral releases toxins that are harmful to other corals. Have some activated carbon running to help absorb those toxins. Examine the coral to see if you can see any areas that look rotten or are dissolving away. In that case, the coral is sick and you may need to cut off a healthy area in order to regrow it elsewhere. Mitch

It just looks closed up to me. How long have you owned it?
