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.
Yellow Perch
The yellow perch is a schooling fish found in lakes and slow rivers across North America. Its golden-yellow body with dark vertical bars is unmistakable. Its sweet, firm white flesh makes it one of the finest-tasting freshwater fish.
