Species Overview

Channel Catfish

The channel catfish is the most abundant and widely fished catfish species in North America. It has a keen sense of smell, with taste buds distributed across its entire body, enabling it to locate food in murky 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.
