Clam nipped by something overnight

[larrysy]

I have a crocea clam since August and has grown bigger with full mantle extension. Discovered today that my crocea clam was missing pieces of the mantle. Don't know what happened. I have a bicolour blenny, a yellowtail damsel and yellow watchman goby. Also some trochus snails and turbo snails.

It still closes when shading it but not fully. Any ideas?

It looks to be pretty upset. For now I'd keep an eye out for further damage, see where the blenny hangs out, etc.

What about other inverts? Shrimp? Crabs? Lobsters?

Just snails. I removed my emerald crab before getting the clam.
