The video shows two discus fish in an aquarium filled with plants and small fish, including neon tetras. The first fish, initially close-up, is light purple. As the camera pans out, another discus fish comes into view. This fish has a red-and-white patterned coloration. The small neon tetras are seen swimming among the plants and around the larger discus fish. The aquarium is illuminated with a strong light, which casts a pinkish-purple hue on the scene.
