Imagine saying 'coy' (shy) but the fish is the opposite—bright and showy. Think: 'KOI are not COY; they show their colours.'

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as just 'карп' (carp), which refers to the common food fish. Specify 'декоративный карп' or use the loanword 'кои'.
Common Mistakes
- Pronouncing it as /koʊ.iː/ (like 'ko-ee'); correct is monosyllabic /kɔɪ/.
- Using it as a plural (e.g., 'kois'); 'koi' is both singular and plural.
- Confusing it with 'coy' (the adjective).

FAQ
Frequently Asked Questions
The word 'koi' is both singular and plural (like 'sheep'). You can have 'one koi' or 'many koi'.
Koi are a type of carp (Cyprinus rubrofuscus) with barbels (whisker-like organs) near the mouth and grow much larger. Goldfish (Carassius auratus) are a different species, generally smaller and without barbels.
Not as adults. Koi can grow over 60 cm long and require large, outdoor ponds with excellent filtration due to their significant waste production.
Koi symbolize strength, perseverance (from legends of them swimming upstream), and good fortune. They are celebrated during Children's Day (Kodomo no Hi) for these qualities.
