The video shows an underwater scene where a fish is swimming near a piece of wood. The fish has a distinctive pattern on its body and is moving around the wood. The water is green, and there is a slight current visible. The fish appears to be alone, and there are no other fish or objects in the immediate vicinity. The wood is covered in algae and appears to be part of a larger structure, possibly a pier or dock. The fish moves in and out of the frame, but the focus remains on its interaction with the wood.
