Here's a pic of my Duncan's...

There are 3 adult heads on it as well as 3 or 4 babies. I have this coral near the bottom of my tank with plenty of flow and it really seems to be doing good...eats like a pig...lol. Below is another pic of some Duncan's, When we got this frag we didn't think it was going to make it as my LFS fragged it too close to the tissue and the skeleton was basically crumbling in pieces but we used super glue gel to seal it up as best we could and now it looks like it might make a comeback as it has 1 adult head that's trying to come out of the center and 2 babies on either side as well as 2 more babies starting to form on the opposite side...
