The video shows a fish swimming around in an aquarium. The fish is yellow with black stripes and has a small mouth. It swims near the bottom of the aquarium, which is covered in sand. There are two rocks on the sand, one of which has a small creature on it. The fish swims around the rocks and the creature, but does not interact with it. The background of the aquarium is dark, but there is a red object and a blue structure visible.
