The video shows several clear glass containers filled with water, each containing a single Betta fish. The fish are seen swimming around in the water, occasionally coming up to the surface. The containers are placed on a white surface, and the background is blurred, focusing the viewer's attention on the fish. The Betta fish are of different colors, including red, blue, and black, and they have long, flowing fins and tails. The video captures the graceful movements of the fish as they navigate the water in their containers.
