The video shows a close-up of a fish tank with two black goldfish swimming around. The fish have long, flowing fins and tails, and they move gracefully through the water. The tank is filled with green plants, which provide a natural habitat for the fish. The water is clear, and the lighting in the tank highlights the shiny scales of the goldfish. The fish seem to be interacting with each other, swimming in close proximity and occasionally brushing against the plants. The overall atmosphere of the video is peaceful and calming.
