1. About Fish Species:

   • Scientific name: Carassius auratus
   • Common name: Shubunkin
   • Family: Cyprinidae
   • Origin: Japan (developed from Common Goldfish)
   • Adult length: 15 to 30 cm
   • Lifespan: 10 to 15 years (can live over 20 years with excellent care)
   • Diet: Omnivore

2. Tank Setup:

   • Shubunkins can be kept in large indoor aquariums or outdoor ponds. A minimum tank size of 100L per fish is recommended.
   • Provide open swimming space along with smooth decorations and hardy aquatic plants like Anubias or Hornwort.

3. Water Parameters:

   • Maintain a pH range between 6.5 and 7.5.
   • Preferred water temperature is 16 to 24°C (60 to 75°F). They are cold-hardy and suitable for temperate climates.

4. Filtration and Water Flow:

   • Use an efficient filter to handle their moderate bioload and maintain water clarity.
   • Moderate water movement is ideal; ensure oxygenation through surface agitation or air stones.

5. Diet:

   • Feed a balanced diet of high-quality goldfish flakes or pellets.
   • Supplement with vegetables (peas, zucchini), live or frozen foods (bloodworms, daphnia), and occasional fruits.

6. Tank mates:

   • Shubunkins are peaceful and do well with other goldfish types, including commons, comets, and fantails.
   • Avoid mixing with slow-moving fancy goldfish or tropical fish with very different temperature needs.

7. Behavior and Compatibility:

   • Shubunkins are lively, social fish that enjoy swimming in groups. They are known for their attractive calico coloration and hardiness.
   • They are non-aggressive but may nip fins if overcrowded or underfed, so ensure ample space and balanced nutrition.
