A school of small, silvery fish swims in unison in dark, murky water. The fish are oriented mostly horizontally and appear to be moving from left to right in the frame. The background is dark and appears to be a rocky or wooded underwater environment. Some of the fish are in sharp focus, while others are blurred due to motion or depth of field. A few small, bright red markings are visible on some of the fish, possibly indicative of a mating display or injury. The lighting is dim, suggesting an underwater environment such as an aquarium or a natural body of water.
