The video shows a large aquarium tank with several jellyfish swimming around. The jellyfish are of different sizes and colors, ranging from translucent to pink. The tank is well-lit, and the water is clear, allowing for a good view of the jellyfish. There are no other objects or creatures visible in the tank. The jellyfish are moving slowly and gracefully, and their tentacles are trailing behind them as they swim. The video is shot from the outside of the tank, and the camera moves slowly to capture different angles of the jellyfish.
