Cuisine & Edibility

Cobia

Firm, moist white flesh with a mild, buttery flavor; moderate fat and large, clean flakes. Extremely versatile — excellent grilled, smoked, raw as sashimi, or used in ceviche.

Corydoras

Not consumed — a small ornamental bottom-dwelling catfish beloved for its peaceful temperament and role as a substrate scavenger in community aquariums.

Species Overview

Cobia

The cobia is a powerful pelagic fish that often follows large rays, sharks, and turtles. Its flattened head and elongated body resemble a shark. Excellent table fare with firm, white flesh, it is increasingly farmed in aquaculture.

Corydoras

The peppered corydoras is a peaceful bottom-dwelling catfish native to South American rivers. It uses its barbels to sift through substrate for food and should be kept in groups of six or more. It can gulp atmospheric air in low-oxygen conditions.
