Skimmer King You're thinking of pyram snails. Stomatella are highly beneficial herbivores.
My vote is for a protozoan infection as what you've described sounds more like the 'pinched mantle' condition. I had it happen this spring, on a Monday my big maxima looked like this and by Friday it was dead. There were many bristle worms all over it as soon as it was dead. Yet I have a smaller maxima that was sitting right next to it in the sand which is still there, fine and healthy as always. I actually have 6 clams in the tank still, 4 of which are in the sand. This picture is from that Monday after I transferred the clam to another part of the system because I thought that maybe it was one of my fish that were bothering it.

Well I hope it was not the worms that killed my clam because I don't want to lose any more anytime soon.

+1 to the bristle worms just being scavengers. I had tons in my old tank and they were always the first to the feast but I never had any trouble with them attacking anything healthy

In my experience, and I've had A LOT of clams, worms come to feast when clams are dead or dying. Putting clams on bases can help, but if your clam doesn't want to stay put, its the way it goes.
It was a very pretty clam, and looked rather healthy from your photo. Although Whatcaneyedo's photo looks like Pinched Mantle, or its just in an awkward state of retraction/extension, which is different.

I don't think it was a pinched mantel for the simple reason that it would never close up all the way. It was open at least 1" when totally closed even when I would pick it up to reposition.

, It was really beautiful. Have to agree that the bristle worms are scavengers after the fact.
