Okay this one is stumping me. I have had an alevapora for about 6 months now and it has been doing great. It survived Katrina and has even trippled in size. Well, I get home today and one half of it is completely retracted. The polyps that are out don't look thier usual robust selves either. I checked all of my levels and everything is in the norm. No salinity, PH, Alk or temp swings. What gives? Of course it has to give me fits just before I have to tear the tank down and move it to the new house. :x This is my wife's fav coral. Any ideas?
