Species Overview

Atlantic Herring

The Atlantic herring is one of the most abundant fish species on Earth, forming massive schools of billions of individuals. It has played a crucial role in European history, fueling trade routes and even wars.

Discus

The discus is often called the 'King of the Aquarium' for its disc-shaped body and stunning color patterns. Native to the Amazon floodplains, it requires warm, soft, acidic water and feeds its fry with a mucus secretion from its skin.
