Cuisine & Edibility

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.
Red Lionfish
The red lionfish is a venomous coral reef fish native to the Indo-Pacific. Its ornate, striped body and fan-like pectoral fins make it popular in aquariums, but it has become a destructive invasive species in the western Atlantic and Caribbean.
