Goldfish (fish)

Goldfish are freshwater fish commonly kept as pets, scientifically known as Carassius auratus. They originate from East Asia and have been bred for centuries for various colors, shapes, and sizes. Goldfish thrive in indoor aquariums or outdoor ponds, requiring clean, well-oxygenated water and proper nutrition. They are social animals that can live for many years, often 10-15 years or more with good care. Goldfish are omnivorous, eating flakes, pellets, and occasional treats like vegetables. They are important in understanding aquatic ecosystems and are popular for their ease of care, making them a common choice for beginners.
