Cuisine & Edibility

Atlantic Bluefin Tuna

The pinnacle of raw fish dining — intensely rich, fatty tuna-o-toro with deep red color and buttery, umami-forward flavor. Commands the highest prices globally in Japanese sushi markets.

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

Atlantic Bluefin Tuna

The Atlantic bluefin tuna is one of the largest bony fish, capable of crossing the Atlantic in under 60 days. A single specimen has sold for over $3 million at Tokyo's fish market. It can maintain a body temperature above the surrounding water.

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.
