Picked this up today wondering what kind it is and what the two mouths are on the side some type of barnacle or something? Thank you!

I am thinking it is a Acropora formosa with a barnacle grown in the branch.

I was kinda thinking it was an A. yongei, but the corallites and their arrangement are not similar.

The "barnacle" could be this (http://www.reefcentral.com/forums/showthread.php?t=2269706).

I have seen those polychaete worms. They are always better to see than the ones with teeth. They will hang out in the rock but they can not build any type of structure like what is seen in the Acro branch.

No problem. That one wound be nice if it had a better browsing layout. You pretty much have to know what you are looking for on that one.

So this thing actually does have a fan that comes out and actually about five others in other places that do not have the mouth this one does. They come out of some of the polyps weirdest thing I have ever seen. Truly a wild piece.

Yep that is a barnacle. That is how they feed.
