IV. Hidden Costs

V. Purchase Recommendations

1. Beginners
   • Budget under ¥1,000 for <20 cm practice koi.
   • Prioritize local farms to avoid transport stress.
2. Intermediate Enthusiasts
   • Budget ¥10,000–50,000 for 40–50 cm premium koi.
   • Attend autumn auctions for better value than spring.
3. Collectors & Investors
   • Always inspect in person; videos cannot capture true swimming posture.
   • Hire an independent appraiser (service fee ~¥5,000 per session).
4. Avoiding Pitfalls
   • Dyed Fish Test: Gently wipe body with alcohol cotton; color transfer indicates dye.
   • Medicated Fish Signs: Cloudy eyes, lethargic swimming may indicate chemical reliance.
   • Fake Lineage Claims: Request pedigrees showing at least three generations.
