Is ANYONE (besides me) keeping (or kept) a raccoon butterfly in a tank with clams?

[Delphinus]

I never see my raccoon pick at the clams. I try to observe a lot, and I just haven't seen him show interest in the clams. To wit, I DID notice he was doing damage to a brain coral (which subsequently got moved into a different tank and recovered.) So I'd like to think I'd notice if he was doing something to the clams. But just I don't see any evidence of it.

BUT ... since his introduction, I have lost 4 clams. Clams that were otherwise doing really well until recently.

2 + 2 = ?

I really hate jumping to conclusions without evidence .. but I hate losing clams even more.
