Species Overview
Atlantic Halibut
The Atlantic halibut is the largest flatfish in the world, capable of exceeding 300 kg. Both eyes are on the right side of its body. It is a slow-growing, long-lived species that has suffered severe overfishing.
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.
