Yes I was referring to Forcipiger flavissimus.
I always thought they were safe, but the reason I ask is that I bought a T. maxima today and put it in my reef. The longnose has gone by it several times and "sampled" it. Of course when he picks at it the clam slams shut immediately and stays that way for several minutes.
Maybe its b/c the clam is new and this behavior will pass??? I am concerned about the clam being acclimated to its new surroundings, as this certainly will not help.
But I have had a squamose in there for quite some time and he has never touched it. But again, the longnose was added after the squamosa.
Any ideas???
