Have Clam will Travel ....?

The star astrea has a hitchiker.
The clam is about 1/4 inch.
Only noticed her when she open and closed quickly.

What kind of clam is this?

Ooh cool, I'm not sure what kind it is but little hitchhikers like this are my favorite part of this hobby!

Looks like a tiny Lopha cristagalli, the cockscomb oyster.

The ride changed.
My red hermit was always attacking this snail. One morning the shell had a new owner. It's now the hermit.
Wonder if the hermit know about the extra load.
