Species Overview
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.
欧洲鳗鲡
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.
