The video shows a close-up view of a coral reef with various types of coral and fish. The coral reef is made up of different colors and shapes, with some coral appearing to be purple and others appearing to be brown. There are several fish swimming around the coral, including a clownfish and a blue tang. The clownfish is orange with white stripes, while the blue tang is blue with a yellow tail. The fish are swimming in and out of the coral, and the camera pans around to show different angles of the reef.
