The video features a single red Betta fish with long flowing fins and tail. The fish is seen swimming in a tank of water, occasionally turning and twisting its body. The Betta fish's scales have a shiny appearance, and its fins and tail are translucent with a slight red tint. The background of the tank is blurred, but it appears to be a dark color, possibly black or dark blue. There are no other fish or objects visible in the tank.
