Our Guide To Keeping Oranda Goldfish

1. About Fish Species:

   • Scientific name: Carassius auratus
   • Common name: Oranda Goldfish
   • Family: Cyprinidae
   • Origin: Selectively bred from the common goldfish, native to East Asia
   • Adult length: Up to 20-31 cm, but commonly around 15-20 cm in captivity
   • Lifespan: 10 to 15 years, with proper care can live longer

2. Tank Setup:

   • Oranda Goldfish require a spacious tank with at least 75 liters per fish to thrive.
   • Provide ample swimming space and consider the potential adult size when selecting the tank.
   • Include soft plants and smooth decorations to prevent damage to their delicate fins and wen (head growth).

3. Water Parameters:

   • Maintain water temperature between 18 to 22°C (64 to 72°F).
   • They tolerate a pH range of 6.5 to 7.5, but stability is crucial for their health.

4. Filtration and Water Flow:

   • Use a filter with a low to moderate flow rate to avoid stressing the fish.
   • Orandas are messy eaters and produce more waste, so efficient filtration and regular water changes are crucial.

5. Diet:

   • Oranda Goldfish are omnivores and should be fed a varied diet including high-quality flakes, pellets, and fresh vegetables like peas and blanched spinach.
   • Supplement their diet with occasional treats of live or frozen foods such as bloodworms, brine shrimp, and daphnia to promote optimal health and coloration.

6. Tank mates:

   • Orandas are generally peaceful but avoid keeping them with species that may nip their long fins or compete aggressively for food.
   • They do well with other fancy goldfish varieties like Ryukins, Ranchus, and telescopes.

7. Behavior and Compatibility:

   • Orandas are active and curious fish that appreciate a well-decorated tank with places to explore.
   • Provide them with a calm environment to thrive and showcase their distinctive appearance and behaviors.
