So has anyone have this happen to their crocea clam? I returned home from the weekend and found that my clam had fallen off the live rock where it was attached to. There was nothing in my tank that could have knocked it off. Upon further investigation, the spot where it used to be attached to, had the clams foot and a thick piece of flesh attached. The clam's foot had separated from its body!!! The weird thing is that where the clam fell, it had attached new a new foot. I read that if a clam get its foot cut off, it dies. However in this situation, my clam completely left its foot behind. Has this happened to anyone else?
