Goldfish Care and Maintenance

Goldfish can live as long as cats, but many die young due to poor tank conditions. Waste like ammonia is harmful, and beneficial bacteria are needed to break it down. Setting up a tank requires patience, as bacteria take time to grow. A large tank is essential to dilute waste, and regular water changes are necessary. Monitoring water quality and interacting with goldfish can prevent diseases and promote growth.
