Cuisine & Edibility
Discus
Not consumed — a prized ornamental aquarium fish known as the 'king of the aquarium' for its disc-shaped body and brilliant colors.
Goliath Grouper
Firm, flaky white flesh with a mild, sweet flavor; harvest is heavily restricted or banned throughout most of its range due to Vulnerable status. Catch-and-release strongly encouraged.
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.
Goliath Grouper
The goliath grouper is the largest grouper in the Atlantic Ocean. This massive reef dweller can swallow prey whole and produces a distinctive booming sound by contracting its swim bladder to ward off intruders.
