Could anyone tell me what this is?

It came attached to LR I bought, it appears to have a ruffled look...Any thoughts?

Looks like an acan

I'm not sure of it being an acan, it closes up at night and it seemed to appear out of nowhere...

 

[khaosinc]

possibly a rock flower anenome?

I agree with khaosinc , or possibly some other pest anemone!

What kind of Live Rock?

It kind of looks like a very small Caribbean Rose Brain Coral.

We get alot of the Rose Brains in on Florida Aquacultured rock, and they can be really cool corals as they grow.
