Species Overview
Blue Marlin
The blue marlin is the pinnacle of big-game fishing. Found in tropical and temperate Atlantic and Indo-Pacific waters, it can exceed 500 kg and is known for spectacular aerial displays when hooked.
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.
