Ok, two questions here.....

first, does anyone know if a coco worm and a red coris wrasse can exist in the same tank, or will the coris rip the heads off the coco worm?

Second, does anyone have any suggestions on how to get a crocea clam off a rock? He's quite well attached, and the rock is too big to fit into my tank (haven't brought him home yet, till I see if I can get him off). Ideas anyone?
