Tiny clams in my fuge???

[phishcrazee]

As I was transferring the contents of my refugium to my sump, I found about 6 of these tiny "clams" attached to my LR. They are about the size of a quarter, some are white, some are darker, and they open up about a 1/4" or less when things are calm. They are about the consistency of a hard toenail, from what I can tell. I know they have multiplied, as I remember seeing one a few months back, wondering what it was, but then got busy and forgot about it. Does anybody else have these? Does anybody know what they are exactly? Sorry for the small picture, but won't let me make it any bigger

Phis,


I have seen these before in the past in some live rock I had in my fuge as well, I can't remember the name but I do know that they are a true filter feeder and will do well in your fuge. They are plus.
