ID Please...Branching Coralline?

[Zen Reeferer]

I've got bunches of this growing like crazy on the live rock in our (2w/gal) frag tank, and some of the shadowed spots in my main display...This example is about 1/4" tall.

I'm thinking it's branching coralline algae. Any chance that's right? If so, how large can it get?
Thank you
Jim

Not sure man, but it does look kinda cool. It would be interesting to know what it is...

Well,how big do any of them get? I believe they are Foraminiferans. I have them all over my tank. A good thing as far as I know. Check out this article for a little more information.
