[Ok, no comments from the peanut gallery about my title...
Seriously though, I have a Brain Coral, Wellsophyllia - Metallic that has done great since I got it (about 1 year old). Well, one day last week, it was all small during the day like it gets when it is sleeping. I thought, "well, it's done this once or twice before and is usually back to normal the next day." Unfortunately, the next day it was not fine. It looked worse. Tissue recession taking place. I also have a red Brain Coral, Lobophyllia which is doing just fine (all the other corals look fine, too). I did all the tests (ammonia, nitrite, nitrate, phosphate, alkalinity, salinity, PH...) and everything was fine (actually, all the tests showed my parameters were better than they ever have been). I moved it off the substrate (where it always has been) and moved it on a small rock about 1 inch off the substrate, thinking maybe something was bothering it. It "puffed" back out slightly the next day, but not half as big as it has always been. It was looking sickly again today. It still has all its coloring, too.
Any ideas on anything else I can check on?]
