Starting with Koi: Research, Clubs, and Proper Pond Design

Seeks general info on breeding and raising koi.

Essential First Steps

Build the right pond: Koi need large volume (1,000+ gal each), depth (≥4 ft), high-quality filtration (bottom drain, sieve, biofilter), and minimal plants (koi destroy them).
Join a koi club: Zen Nippon Airinkai (ZNA) affiliated clubs offer mentorship, shows, and vetted dealers.
Study water chemistry: Ammonia, nitrite, pH, KH, GH, oxygen, temperature.
Learn quarantine: 4–6 weeks for every new fish.
Reputable resources: Koimaster.be (Dutch), INPC website, ZNA clubs worldwide.

Koi keeping is a discipline, not a hobby. Start with infrastructure, then acquire fish.
