Description
The Galápagos Thread Herring (*Opisthonema berlangai*) is a schooling marine fish native to the Eastern Pacific, particularly around the Galápagos Islands. These silvery fish are characterized by the elongated last ray of their dorsal fin and form vast schools, serving as a crucial food source for many larger marine predators. Due to their schooling nature and size, they are primarily found in public aquariums rather than home setups.
