Fancy Goldfish, also known as ornamental goldfish, originated from selective breeding of the common goldfish in China, focusing on enhancing unique physical traits. These fish are notable for their rounded, egg-shaped bodies, double tails, and elaborate fins, which differ from the streamlined shape of common goldfish. Popular varieties include the Oranda, recognised for its distinctive raspberry-like head growth called a wen, and the Ryukin, famous for its prominent shoulder hump and flowing fins. In terms of temperament, fancy goldfish are peaceful and social, making them suitable for community tanks with other slow-moving fish. They thrive in well-maintained aquariums with powerful filtration to handle their waste, and they require a spacious environment with clean, cool water maintained between 18-22°C. Due to their body shape, they are prone to swim bladder issues, which necessitates feeding high-quality sinking pellets and blanched vegetables.
