Our Guide To Keeping Butterfly Ghost Koi Carp Fish

1. About Fish Species:

   • Scientific name: Cyprinus rubrofuscus (Koi variant)
   • Common name: Butterfly Ghost Koi Carp
   • Family: Cyprinidae
   • Origin: Selectively bred in Japan, developed from common carp
   • Adult length: Up to 90 cm
   • Lifespan: 25 to 35 years (with proper care)
   • Diet: Omnivore
   • Care Level: Moderate
   • Temperament: Peaceful

2. Tank Setup:

   • Butterfly Ghost Koi Carp are best kept in large outdoor ponds, but can be kept in very large indoor aquariums if necessary (minimum 1000L).
   • Ensure the pond or tank has smooth substrate, shaded areas, and plenty of space for swimming due to their long, flowing fins.
   • Use pond plants such as water lilies or submerged plants like hornwort for natural enrichment and shelter.

3. Water Parameters:

   • pH range: 6.8 to 8.2
   • Temperature range: 15 to 25°C (59 to 77°F), though they can tolerate wider ranges temporarily

4. Filtration and Water Flow:

   • Use a powerful filtration system to handle the bioload of these large fish, especially in outdoor ponds.
   • Provide moderate water flow, ensuring oxygenation without creating strong currents that may disturb their long fins.

5. Diet:

   • Feed a varied omnivorous diet including high-quality koi pellets, vegetables like lettuce and peas, and occasional protein sources such as shrimp or worms.
   • During colder months, reduce feeding as their metabolism slows down significantly.

6. Tank mates:

   • Suitable pond mates include other koi, goldfish, and peaceful cold-water species.
   • Avoid aggressive or fast-swimming fish that might outcompete them for food or nip at their fins.

7. Behavior and Compatibility:

   • Butterfly Ghost Koi Carp are social and do well in groups, often displaying graceful, slow swimming behaviors.
   • They are peaceful and non-territorial, making them excellent additions to community ponds or large, mixed-species aquascapes.
