Found under Monti cap :(

These guys had chomped a hole through my Monti cap. Now I found some under a frag plug. What are they. Can't be good if the made a hole in my cap.

Hard to tell from pics, but looks like a tiny clam.

If that is the case, it would be a good thing.

I am not sure why the first one found was attached to my cap as the last two in pic attached to a frag tile.

A pic of little bugger.
