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.
Yellowfin Tuna
The yellowfin tuna is a pelagic predator found in tropical and subtropical oceans worldwide. Capable of speeds exceeding 75 km/h, it is prized both as a sport fish and for its high-quality sashimi-grade flesh.
