Oranda Bronze

The Oranda Bronze is a variant of the fancy goldfish, highly prized for its metallic sheen and distinctive hood, or wen, which gives it a unique, ornamental appearance. As a member of the Carassius auratus species, it thrives in aquaria where careful attention is given to water quality, tank size, and compatible companions. While its luxurious features are eye-catching, maintaining the health and longevity of this fish requires a well-structured environment and consistent care.

The Best Aquarium Size for Oranda Bronze

Due to its size and waste production, the Oranda Bronze requires a spacious tank to maintain optimal health. A minimum of 100 litres is recommended for a single adult fish, with an additional 40 litres per additional fish. A larger tank reduces nitrate buildup and offers ample swimming space for their long fins.
