Several pieces of coral, some bright green and others darker purple, are scattered throughout the tank. A Copperband Butterflyfish, distinguished by its white body with orange stripes and a prominent black spot near its tail, swims around the coral formations. The camera moves slightly to follow the fish's movement as it explores the tank. The lighting is bright, showcasing the colors of the fish and coral.
