Our Guide To Keeping Koi Fish

  1. About Fish Species:

    • Scientific name: Cyprinus carpio
    • Common name: Koi
    • Family: Cyprinidae
    • Origin: Japan (originally domesticated from common carp in China)
    • Adult length: 60 to 90 cm (some varieties can exceed 100 cm)
    • Lifespan: 25 to 35 years (some koi have been known to live over 50 years)
    • Diet: Omnivore
    • Care Level: Moderate
    • Temperament: Peaceful and sociable
  2. Tank Setup:

    • Koi require large outdoor ponds with a minimum of 1500L per fish. Bigger ponds allow for proper growth, movement, and water quality management.
    • Include open swimming space, natural plants, and shaded areas. A pond depth of at least 1.2 meters is recommended to protect them during colder months.
  3. Water Parameters:

    • Maintain a pH between 7.0 and 8.0 for optimal health.
    • Ideal temperature range is 15 to 25°C (59 to 77°F). Koi are cold-hardy and can overwinter in deep ponds.
  4. Filtration and Water Flow:

    • Use a powerful pond filtration system to handle high waste output and maintain clean, oxygen-rich water.
    • Moderate water flow is best, supported by waterfalls, fountains, or air stones for proper aeration.
  5. Diet:

    • Feed a balanced koi pellet that supports growth, immunity, and coloration.
    • Supplement with fruits (oranges, melon), vegetables (peas, lettuce), and protein sources like shrimp, silkworms, or bloodworms.
  6. Tank mates:

    • Koi are peaceful and get along with other koi, large goldfish, orfe, and tench.
    • Avoid aggressive or fin-nipping species, as well as small tropical fish that may not tolerate the same conditions.
  7. Behavior and Compatibility:

    • Koi are intelligent, social, and often recognize their caregivers. They are graceful swimmers and can become quite tame.
    • They thrive in groups and contribute beauty and tranquility to any garden pond setup.
