In the video, a person is holding a plastic bag filled with water and several small fish. The person is moving the bag around, allowing the fish to swim around inside. The fish are small and appear to be of the same species. The plastic bag is transparent, allowing a clear view of the fish and the water inside. The person's hand is visible holding the bag, and they seem to be in a room with a fish tank in the background. The fish are active and moving around inside the bag, and the water is clear.
