Need better picture. If I am the OP, I would crop the picture so that the think he want to ID is in the middle, or/and describe it. I see a stomatella sp. snail, another black color snail and a Xenia colony.

Here's a pic I cropped I will take better one post later I know it's not a snail it has been there for a few weeks it won't move around it will suck back up into rock sometimes when you shine a light on it though

if you see web like substance coming out of it, I believe it's Vermetid Snails
