What kind of Clam is this?

[3s1k]

I got a zoa frag from the UC live sale and it was on this clam shell. Well after a few weeks I noticed the shell was opening and closing.

You can see its partially open and has something feather sticking out I'm assuming to catch food. Any ideas?

It's a type of bivalve. Good filter feeder

Looks like a hitchhiker bivalve. Non photosynthetic filter feeder.

Haha both commented that same time. Thanks. I did notice him after feeding some mysis shrimp juice. He's in my work tank so hopefully he does ok.
