The video shows three small fish swimming in a clear container filled with water. Two of the fish are a vibrant shade of red, while the third one is a purple-red color. The background is a plain white surface, possibly a sink, and there's a blue-ish shape visible at the bottom of the container. The fish appear to be GloFish, a type of genetically modified tetra, due to their bright colors. The camera angle is slightly low, looking up at the fish, and the lighting is fairly bright.
