FAQs – Large Koi For Sale
Q: What size is considered a "large" koi?
A: Our Large Koi category contain koi that measure 10 to 15 inches long. They're mature
enough to display strong patterns and structure, yet young enough to continue growing.
Q: Can I buy large koi fish online from Kloubec?
A: Absolutely! You can safely buy large koi online through our website. Every fish is carefully
selected, packed with oxygen and insulation, and shipped directly to your door.
Q: Will these koi grow into jumbo koi?
A: With the right pond size, nutrition, and care, many of our large koi can continue growing into
jumbo koi—some reaching over 24 inches!
Q: Are large koi good with smaller koi?
A: Yes, as long as the size difference isn’t extreme. We recommend mixing koi that are within 6-
8 inches in size to avoid accidental bullying or feeding issues.
