Species Overview
Corydoras
The peppered corydoras is a peaceful bottom-dwelling catfish native to South American rivers. It uses its barbels to sift through substrate for food and should be kept in groups of six or more. It can gulp atmospheric air in low-oxygen conditions.
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.
