Speaking of clams...just noticed tonight that my squamosa looks like it may have been "picked" at. I see thru him in one spot smaller than a size of a dime. Wonder if this hijacker crab that I can't seem to catch or my blue legged hermit is the culprit. Anything special I need to do? The clam seems fine & is fully open like nothing has happened. Will it heal & close on its own?
