Corrected entry: While J is fighting the fish, and it has him pinned against the wall outside, there is an ATM-like machine beside them. When J rips out the creature's heart, it falls over towards the machine. The fish's shadow is cast on the wall, but as it passes over the ATM, no shadow falls on the machine. (00:16:55)

Correction: The fish does have a shadow as it falls, but it falls about ten feet from the ATM, and the shadow trails accordingly. If you follow the arc of the shadow as it falls, it's on a flat surface, and the ATM sticks out about three feet. Therefore, the shadow would have gone along the side away from the camera's view, and not in front of the machine.
