5-6” Koi

5–6” Koi Carp (12–15cm)

Ready to upgrade your pond with fish that actually stand out?

Each koi is individually selected for:

• Clean, vibrant colours
• Balanced patterns

👉 No dull, washed-out fish — only quality you’ll notice instantly

🌟 Why choose 5–6” koi?

• More visible straight away than smaller koi

• Ideal for building a high-quality pond look fast

📦 What to expect

• Size: 5–6” (12–15cm approx.)
• Mixed varieties (depending on availability)

• Covered by our Live Arrival Guarantee

💧 Care Requirements

Koi at this size are hardy, but proper setup = faster growth + better colour:

• Filtration: Essential (koi produce waste quickly as they grow)
• Water parameters:
• Ammonia: 0
• Nitrite: 0
• Nitrate: Low

👉 Tip: Maintain good feeding and water quality — these koi will reward you with rapid growth.
