The video shows a blue fish swimming in an aquarium. The fish has a vibrant blue body with yellow and orange markings on its dorsal fin. It is moving gracefully through the water, surrounded by rocks and gravel at the bottom of the tank. Another fish can be seen partially in the background, but it is not the main focus. The lighting highlights the colors of the fish and the texture of the environment.
A large blue fish with a yellow stripe along its dorsal fin is swimming in an aquarium with a gravel bottom and rocks. The fish gradually turns its body to the right, moving its fins and tail to propel itself forward. As it continues to swim, the fish's tail fin moves more prominently, and its body follows the turn. The fish's movement is smooth and continuous, with its tail fin gradually lowering as it completes the turn.
