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.
Peacock Bass
The peacock bass is the crown jewel of Amazon basin sport fishing. Despite its name, it is actually a large cichlid. Known for explosive topwater strikes and powerful, drag-screaming runs in tropical rivers and lagoons.
