Cuisine & Edibility

Corydoras

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

玻璃梭鱸

Considered one of the best-tasting freshwater fish; sweet, flaky white flesh with very low fat. Ideal pan-fried, battered, or baked — a North American culinary favorite.

Species Overview

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.

玻璃梭鱸

The walleye is the largest member of the perch family and the most sought-after freshwater food fish in North America. Its reflective eyes give it exceptional low-light vision, making dawn and dusk prime feeding times.
