In the video, a person is seen holding a red object in their hand. They are standing in front of a glass tank that contains water and several fish. The person appears to be feeding the fish, as they move the red object around in the water. The fish swim around the object, seemingly attracted to it. The person continues to move the object around, and the fish continue to follow it. The tank is well-lit, and the water is clear, allowing for a good view of the fish and the person's actions.
