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.

Swordfish

The swordfish is a highly migratory pelagic predator recognized by its long, flat, pointed bill. It can dive to depths exceeding 2,800 meters and possesses a specialized organ that heats its eyes and brain for improved vision in cold, deep water.
