The video shows a group of piranhas swimming in an aquarium. The fish have a distinctive appearance with silver bodies and red bellies. They move gracefully through the water, their fins and tails propelling them forward. The background features some aquatic plants and rocks, creating a naturalistic environment for the fish. The lighting highlights the shiny scales of the piranhas, making them stand out against the darker surroundings.
