    Anyone know what these microscopic bugs are? ID

    Hi, I’ve just finished cycling my tank and I’ve put a grain of sand under the microscope to see this? There like little bugs zooming round near/next to the grain of sand. Anyone know what it is?

    Purchased as live rock, but it moves.

    I assume this is a clam because it opens and closes every now and then, but I don’t see any eyes. Bought it from a LFS as live rock, but it much have gotten mixed up. Any chance on ID/ how to take care of it in an establishing tank.
