I have a CBB in with 5 clams at the moment. There don't seem to be issues .... yet. I did have a moment on the weekend when I put in a new derasa where he seemed to sample the mantle, but I gave him an oyster to work on instead and he's left the clam alone since then.
But, it's something I watch for. I just basically don't trust the CBB completely as he eats nothing except for frozen foods (mysis or brine) or live foods (mussel, oyster or clams). He's gotta be hungry (his own fault for being so stubborn but nevertheless it's something I worry about).
He wasn't all that great at ridding the tank of aiptasia either. Six months after I got him I found myself still needing to inject a few of the buggers with kalk. He might have gotten some but certainly didn't "rid the tank of them." (Stupid fish. He's lucky he's pretty otherwise I'd have sold him months ago!)
Like most things, an element of hit and miss, I guess..
