Cuisine & Edibility

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.

Goliath Grouper

Firm, flaky white flesh with a mild, sweet flavor; harvest is heavily restricted or banned throughout most of its range due to Vulnerable status. Catch-and-release strongly encouraged.

Species Overview

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.

Goliath Grouper

The goliath grouper is the largest grouper in the Atlantic Ocean. This massive reef dweller can swallow prey whole and produces a distinctive booming sound by contracting its swim bladder to ward off intruders.
