Our Guide To Keeping Tri Colour Oranda Goldfish

1. About Fish Species:

   • Scientific name: Carassius auratus (var. Oranda)
   • Common name: Tri Colour Oranda
   • Family: Cyprinidae
   • Origin: Domesticated in China; further developed in Japan
   • Adult length: 15 to 20 cm
   • Lifespan: 10 to 15 years (can live longer with excellent care)
   • Diet: Omnivore
   • Care Level: Moderate
   • Temperament: Peaceful

2. Tank Setup:

   • Tri Colour Orandas require a tank of at least 75L (20 gallons) per fish due to their size and delicate nature.
   • Decorate with smooth, rounded ornaments and avoid sharp items that can damage their wen (head growth).
   • Use fine gravel or sand as substrate and consider silk or soft live plants like Anubias or Java Fern.

3. Water Parameters:

   • Maintain a stable pH between 7.0 and 8.0.
   • Keep the temperature between 18 to 23°C (64 to 74°F). Orandas prefer slightly cooler water than tropical fish.

4. Filtration and Water Flow:

   • Use a high-capacity filter to manage their waste, but ensure the water flow is gentle to avoid stressing these slow swimmers.
   • Regular water changes (25–30% weekly) are essential to maintain water quality.

5. Diet:

   • Feed a balanced diet of sinking goldfish pellets or gel food to avoid buoyancy issues.
   • Supplement with vegetables like blanched peas, spinach, and occasional protein like bloodworms or daphnia.
   • Avoid floating food, as it can lead to swim bladder problems.

6. Tank mates:

   • Best kept with other fancy goldfish varieties (e.g., Ranchu, Fantail, Ryukin) that have similar swimming speeds and temperaments.
   • Avoid mixing with fast or aggressive species and tropical fish requiring warmer water.

7. Behavior and Compatibility:

   • Tri Colour Orandas are calm, social, and can be kept in small groups of fancy goldfish.
   • They are not aggressive and enjoy interacting with their environment and tank mates.
   • Handle with care, as their wen and fins are delicate and can be injured easily.
