Aiptasia Killing Clams?

[Ryan7]

Clams are not affected by aptasia stings, your clams died of another cause.

Had one on my maxima since the day I bought it last March. Tried picking it off several times but it always came back. Finally got the bastard a couple of weeks ago. Never seemed to bother the clam but it was the only aiptasia in my tank and I didn't want it to spread.
