I was cleaning the glass on my tank today and found this clam stuck in a corner. I didn't see it until I had bumped it with the magnet cleaner and it fell to the sand. Anyone have any idea what kind of clam it is and is it something that I shouldn't have in my tank?
Well, guess it doesn't matter because between the time I took the photo and posted it here the clam has moved itself off the rock and disappeared into the sand.
