I found one of my recently acquired coral frags turned over one morning...upon closer inspection, I found this clam attached and growing on the underside. Any idea what type it may be and what I should do with him? Should I pry him off and put him in a spot where he can get some light? I'm asking because it looks like he flipped the frag over. The pic is a zoomed in shot..he's probably about a 1/2 inch or so. I've never dealt with clams of any kind so I don't just want to pry him off the frag. I've gotten various feather dusters and a few other things as hitchhikers but never a clam like this. Any advice and info regarding ID would be greatly appreciated. Thanks
