Species Overview
Atlantic Bluefin Tuna
The Atlantic bluefin tuna is one of the largest bony fish, capable of crossing the Atlantic in under 60 days. A single specimen has sold for over $3 million at Tokyo's fish market. It can maintain a body temperature above the surrounding water.
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.
