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.
Rainbow Trout
The rainbow trout is native to cold-water tributaries of the Pacific Ocean in Asia and North America. Widely introduced worldwide, it is prized by anglers for its acrobatic leaps and beautiful coloration.
