What is this?

[jords]

Hey, new to the boards, so sorry if this isn't posted in the right spot. I'll get it one day!

Anyway, I'm trying to figure out what exactly this is. It's the best picture I could get of it (sorry about the damsel, he really wanted his picture taken this morning). It looks like lettuce or something growing up from the live rock. This is the biggest one, but there are a couple other small ones coming up. Any help would be great, thanks!



It's right under his bottom fin. (PS, yes I'm aware of that hair algae in the picture too - working on it!)
