Referred to as the Purple Grape Monti, this scrolling coral has become a dominate coral high up in my reef. It's pretty, but since it grows rather fast it actually overtook (and shaded) other SPS corals which killed them. Sometimes you have to choose what you want more. I really like the look of this coral, and avoid fragging it unless I must.
It doesn't frag cleanly; it's like breaking a potato chip. You can't just snap of a tiny straight piece, so when you cut into it results will vary. That's why I try not to touch it, because I hate to mess up the pretty shape. You may be able to snap off the tiny center whorl of the colony and leave the main section intact.
