It's probably an Aiptasia anemone; they can spread like crazy in some cases. Ideally, you should remove it in a way that doesn't pop it or leave any behind.

What do they do?

They sting corals & other livestock, and they will completely cover the live rock if you don't eliminate them or at least keep them under control.

For example:

I had something very similar to what you're describing. The only way I could describe it was a tiny red anenome-looking thing. It was white on the inside and instead of the long "fingers" that taper, it had tiny clear balls that expanded and contracted. I was told it was harmless and to let it go and see what happened. If your guy looks like that, I'd be curious to see what it looks like full-grown. I accidentally killed mine. I have a pic of it under a thread in General Salt. "Some things in the tank." Does it look like the third set down?

If it looks brownish/transparent it is probably an aiptasia like he mentioned earlier...in order to remove, take a small needle like object and insert lemon juice into it. works wonders.
