Cuisine & Edibility

Arapaima

Large, firm white fillets with a mild, clean flavor and low fat; historically a staple protein in Amazonian communities. Often salted and dried; sustainable harvest is tightly regulated.

Common Goldfish

Not consumed — a classic ornamental aquarium and pond fish; its vivid color and hardy nature make it one of the world's most popular decorative species.

Species Overview

Arapaima

The arapaima is one of the largest freshwater fish in the world, reaching up to 4.5 meters. An obligate air-breather, it must surface every 10-20 minutes to gulp air. Its tongue is bony and used to crush prey against the roof of its mouth.

Common Goldfish

The goldfish was one of the first fish to be domesticated, with selective breeding in China dating back over 1,000 years. Despite common misconceptions, goldfish can live 10-15 years with proper care and require far more space than a small bowl.
