SO to give you some background I finally bought a clam after wanting one for the past year or so and found one on sale at my LFS. I have totally forgotten what type, but it is only about two inches big and I am just holding it in my 10 gallon until my thirty is up and running. So yesterday morning I put the clam on the rock instead of the sand just to see if it would like it better, only to come home about 12 hours later to see it back in the sand and the foot still on the rocks. Now with this being my first claim I freaked out and searched and searched all of the forums and found about 984859435 answers to the same question. So I am here to ask you all, is it doomed? I put it back in the sand over night and this morning it was still responding well to light and shadows and it was opened, but being the person I am, I have stressed out about it all day.
