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.
Nile Tilapia
The Nile tilapia is the most widely farmed fish species in the world, cultivated in over 120 countries. Originally from Africa, it is a hardy, fast-growing mouth-brooder that thrives in a wide range of environmental conditions.
