The video shows a row of glass jars filled with water, placed on a shelf under a light. The jars contain various types of fish, including guppies and betta fish, and some have green plants growing in them. The fish are swimming around and interacting with each other and their environment. The jars are transparent, allowing a clear view of the fish and plants inside. The light above the jars illuminates the water, making the fish and plants visible. The shelf appears to be made of metal and is placed against a wall.
