In this video, we see a person's hand holding a small fish over an aquarium. The fish is then released into the water, and we can see it swimming around the tank. The aquarium is filled with colorful gravel and has a decorative piece of driftwood. The fish appears to be a small, pinkish-purple creature with a long tail. The water is clear, and we can see the fish swimming around the tank, exploring its surroundings.
