I have had one for anout a year. Very interesting coral. Non-photosynthetic. After researching, I glued my frag plug upside down in a cave. It has since grown quite a bit. I'll post a pic tomorrow.
I have fragged him twice. I found it hard to keep the frag on a plug. I read that a toothpick piercing the flesh and rubbebanded to a plug works. But not for me. Maybe a needle and thread might work better.
I have a little one still loose on my sanded. It still polyps up at feeding time so it's alive. Just loose. You can have the little guy if you want him.
