Hitch hiker ID please

[PapaMcEuin]

Bought a frag and came with a hitch hiker. Help would be appreciated. Vid is on YouTube for PapaMcEuin.

I guess I should clarify, I know the tiny fan worms, I bought it for the green frilly softy ( frankly I don't remember the name of that either) but to the bottom left is a two valve heart little thing that pumps occasionally. Found another on the back side. What is that?

 

[GerritM]

Probably Microprotula sp.

As far as the "two valve heart thing", look up images of "styela clava". It is a type of bi-valve. I have had quite a few on rock from the Gulf of Mexico.

Yup Had a few myself. Might still be there for all i know. Can't see that side of the rock for some time now
