The video shows a group of goldfish swimming in a blue aquarium. The fish come in different colors, including orange, yellow, and white. They have long, flowing fins and tails that move gracefully as they swim. The aquarium appears to be well-maintained, with clear water and a clean environment. The fish are of various sizes, but all seem to be healthy and active. The blue background of the aquarium provides a striking contrast to the vibrant colors of the fish.
