Need an ID on this thing!

These aren't the best pictures, but it was hard to get a decent one.
I'm trying to figure out what these are. They are at the bottom of a rock, on the far left of the tank. They almost look like brown zoo like things. Only thing I'm unsure about in my tank, they just randomly showed up one day.

I don't know but maybe this will help someone else ID it

And You'd think I'd be able to get better pictures with my camera, considering I have a DSLR. Oh well, maybe one day I'll play with it and learn

Are they raised at all by the way? They kinda look like limpets.

 

[darkcirca]

It's like a tiny group of like 10 things (little heads) all raised up about 1/4" about, but you can't see a base as they are surrounded and the side ones are blocking the view in.

 

[Grins]

Look online for keyhole limpets and see if they look like them.

Judging by the appearance of corallites on the right side, I would say some sort of Faviid stony coral--or "brain" corals.

 

[Grins]

That would be a primo hitchiker if so.

 

[darkcirca]

They look furry too almost, figured I'd add that.

It looks very much like my brain/moon/pineapple coral. It has a million names. I have one and it is a huge rock the size of a brain with those little pockets on it, most of my pockets have died from the previous owner, I only have about 15 left out of like 50. Mine open and extend at night to about 3/4 of an inch.
