Whats happening to my coral?

I noticed this a couple days ago, it doesn't seem to be getting worst. The only thing I can think of is maybe an emerald crab or that it is growing attached to the rock. I have stopped feeding the fishies as much, so I think the crabs are getting hungry maybe?

Just looks like a normal break/frag. Don't be alarmed. Granted if you see more of this happening then you might have something lurking around in the rock.

+1 to the cloves touching it. Probably need to trim the garden a tad and the problem will be corrected.
