Goldfish are one of the most popular and recognizable freshwater aquarium fish in the world. Originally from East Asia, they have been bred for centuries into various shapes, sizes, and colors—ranging from classic orange to white, black, and even calico. Goldfish are peaceful and can live in both bowls and larger tanks, though they thrive best in spacious, well-filtered environments. They are social and intelligent, often recognizing their owners and learning feeding routines. With proper care, goldfish can live 10 to 20 years or even longer. Their beauty, gentle nature, and long lifespan make them beloved aquarium pets worldwide.
