Clam Killers?

[snarkes]

Alright. So i've had a baby Maxima clam in my tank for about a week and a half now. Everything seemed great, he was always open and it didnt appear that anything was bothering him. The only problem I had was that I couldnt get him to attach to a rock... so he stayed in the sand where he was happy. Well, I came home this afternoon and the only thing I saw left was his empty shell... I mean that sucker was cleaned out. Now, I dont know what could have happened to him in such a short span of time. The LFS seems to think that it was the result of bristleworms coming through the foot. I thought maybe it was the queen conch I have? but like I said, nothing had been bothering it before, not the crabs, fish or the conch. My parameters are still good:

Nitrites and Amonia = 0
Nitrates = trace
Calcium =~420
Salinity = 1.025
Temp = 79

Any ideas?

I don't know if the bristleworms killed the clam but I'm pretty sure they're the ones to clean it out.

Bristleworms are scared of anything that moves .. for the most part
