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.

Red Snapper

Moist, sweet white flesh with a nutty undertone and firm texture. Prized for whole roasting, pan-searing, and ceviche; a cornerstone of Gulf Coast and Caribbean cuisines.

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.

Red Snapper

The red snapper is one of the most commercially valuable reef fish in the Gulf of Mexico. With its distinctive rose-red body and pointed anal fin, it inhabits rocky reefs and artificial structures at depths of 10-190 meters.
