Basically, there is stuff inside the skeleton. You need to wait until there is a lot more room between those two heads; probably AT LEAST until the two present heads have split into more heads. Wait until you are absolutely sure and comfortable with fragging it. Plus, it looks good now. Don't mess with success!
As for Marine Snow, I tried it and it didn't make any difference at all. Probably just pushed up my nitrates. I feed my LPS mysis every once in a while, when I feel like watching the show, but that's only once a month or so. My understanding is that the best food for coral is the kind that comes out of fish, in the good, old-fashioned natural sort of way.
