are clams good

[bald57]

Just noticed in my tank I have what I think is a small clam. It is in a creves of a rock that is in the tank. I see it opening slightly, then next time I look, it is closed. Should I be doing anything with this or just leave it. Right now it is the only rock left in my tank because I have removed all the rest do to an invest of airspate anemonies.

I should be able to put some of the rocks back in today because they have been sitting in fw for a couple of days now.
