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.
Wahoo
Delicate, flaky white flesh with a mild, sweet flavor and very low fat. Among the finest-tasting sport fish; best grilled, seared, or served as ceviche to preserve its subtle flavor.
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.
Wahoo
The wahoo is one of the fastest fish in the ocean, capable of reaching speeds of 97 km/h. Its elongated, torpedo-shaped body and razor-sharp teeth make it an efficient pelagic predator found in tropical and subtropical waters worldwide.
