hello i have a 90 gal Reef, with bout 35 lbs of live rock and on one of the rocks inside of one of the crevices, is this thing that almost looks like two half rocks broken down the middle, its about the size of a nickel, it opens slowly when left alone and visibly has the insides of a clam of some sort, how do i keep it alive and what could it be?
