The video shows a close-up of a fish tank with gravel at the bottom and green plants on the sides. There are two fish swimming around the tank, one of which is a neon tetra. The fish are moving around the tank, swimming near the plants and gravel. The neon tetra is easily recognizable by its bright blue and red stripes. The other fish is not as colorful, but it is still visible against the gravel and plants. The tank appears to be well-maintained, with clear water and no visible debris. The lighting in the tank highlights the colors of the fish and plants, making them stand out against the neutral-colored gravel.
