Rep Cap Oranda Goldfish

About this fish

Rep Cap Oranda Goldfish is a fancy goldfish variety (Carassius auratus) used as a showy freshwater aquarium fish. The “oranda” type is recognized by its distinctive head growth (often called the wen/cap), making it a popular centerpiece fish in community tanks. In the aquarium trade, “rep cap” typically refers to a named appearance line, but this listing is best used as a general guideline for caring for an Oranda-style fancy goldfish.

• Peaceful, social temperament—generally compatible with other calm tankmates
• Well-suited to freshwater aquariums with strong filtration and regular maintenance
