Herring: The Social Shoaling Fish

Clupea harengus, commonly known as herring, is a small, silver-colored fish found in the Atlantic and Pacific oceans. Herring are known for their unique behavior of forming large shoals, sometimes consisting of millions of individuals.

The guppy, scientifically known as Poecilia reticulata, is a small tropical fish native to South America. They are popular among aquarium enthusiasts due to their vibrant colors and unique reproductive behavior.

Guppies have become one of the most common fish in the aquarium trade due to their adaptability, ease of care, and beautiful appearance. They are known for their rapid reproduction and can quickly populate a tank if not controlled. In the wild, guppies inhabit freshwater streams, ponds, and rivers, where they feed on small invertebrates and algae.
