The video shows several black fish swimming in a tank with a light blue bottom. The tank is seen through a glass enclosure, which causes reflections and obscures the view. The fish are mainly dark, with some appearing greyish. One fish is positioned at the bottom right, facing the camera. Another fish is larger and more central, seemingly looking towards the left. Some darker objects, possibly food or tank decorations, are at the bottom of the tank. The glass is also somewhat dirty with visible spots.
