A single Betta fish with a pale, iridescent body and light-colored fins is swimming gracefully near the water surface in an aquarium. A distinct layer of small bubbles, possibly a bubble nest, is visible on the water's surface. The fish's reflection is clearly seen on the back glass of the tank as it moves. Part of a green and brown decorative object is visible at the bottom left of the aquarium. The scene is set indoors, in Reshetnikovo, Russia.
