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.
Northern Snakehead
The northern snakehead is an aggressive freshwater predator native to East Asia. It can breathe air and survive out of water for several days. Considered a destructive invasive species in North America, it provides exciting catch opportunities.
