I bought a colony of this coral, but it started to STN after a week or so. I tried a frag before which also STN'd from the base, but it then survived. It didnt grow for nearly six months and then when it started to show sign of growth and recovery AEFW's wiped out all the SPS from my tank.
When I first got my colony it had the the green ring inside the corrallites too, but they disappeared soon after afterwards.
The colony has been fragged to several pieces in my tank and I have lost 2 frags out of 7 so far. I noticed in the past few days the corrallites have gotten back the green ring...even though everything else is thriving in my tank, this one is just not surviving.
If I can get one of the frags to survive I think long term the frag can grow into a colony...but it is a very hard coral to grow..
