This video captures a group of fish swimming in a tank. The fish are of different sizes and colors, with some being yellow and others being darker. They are swimming around a large piece of driftwood that is in the center of the tank. The fish are moving in different directions, some swimming up and down while others are swimming side to side. The driftwood is covered in algae and has several holes in it. The water in the tank is clear, and the lighting is dim, creating a calm and serene atmosphere.
