Species Overview
European Eel
The European eel undertakes one of nature's most remarkable migrations, traveling 5,000 km from European rivers to the Sargasso Sea to spawn and die. Despite centuries of study, its breeding grounds were only recently confirmed.
Neon Tetra
The neon tetra is one of the most popular freshwater aquarium fish, known for its iridescent blue and red horizontal stripes. Native to blackwater streams of the Amazon basin, it thrives in schools of six or more.
