About

A single jumbo-grade koi individually selected at random from a mixed pool of premium varieties including Kohaku, Sanke, Showa, and Ogon types, ensuring variety without the premium price of a hand-selected specimen. At jumbo grade (25–40 cm), these fish make an immediate visual impact in any established pond and represent significant growth potential and many decades of life ahead. Ideal for adding an impressive large specimen to complete a koi collection without paying collector premiums for a specific variety.

Care Guide

House in a well-filtered pond of at least 5,000 L to provide proper space for a jumbo-grade koi. Maintain pH 7.0–8.5, temperature 5–25°C; cold-hardy through Northern European winters. Feed quality koi pellets adjusted by season. Perform regular water changes and maintain UV filtration for best water clarity. Compatible with all other koi varieties and large pond fish.
