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.
シイラ
Firm, slightly sweet flesh with large, moist flakes and low fat. Excellent grilled, blackened Cajun-style, or in tacos; one of the most popular sport fish for the table.
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.
シイラ
The mahi-mahi, also known as dorado or dolphinfish, is among the most colorful pelagic fish in the ocean. Its iridescent blue, green, and gold body fades rapidly after death. It is a fast-growing species, rarely living beyond five years.
