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.

Thin, delicate white fillets with a sweet, mild flavor and very low fat. Prized on the U.S. East Coast; superb pan-fried in butter, stuffed and baked, or prepared as ceviche.
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.
Summer Flounder
The summer flounder, or fluke, is a flatfish that lies camouflaged on the ocean floor. Born with eyes on both sides, one eye migrates to the left side during development. An ambush predator, it explodes upward to grab passing prey.
