Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'драгоценная рыба' as it is not an established term. Use the specific name 'цихлида-драгоценность' or the scientific name for accuracy.
- Do not confuse with 'золотая рыбка' (goldfish), which is a different species.
Common Mistakes
- Misspelling as 'jewel fish' (two words) – standard is one word or hyphenated 'jewel-fish'.
- Using it as a general term for any bright fish instead of specific cichlids.
- Pronouncing it as 'jool-fish' (/dʒuːl.fɪʃ/) instead of the standard three syllables /ˈdʒuː.əl.fɪʃ/.

FAQ
Frequently Asked Questions
No. Jewelfish are tropical cichlids from Africa, known for aggression and specific water needs. Goldfish are coldwater carp from East Asia with different care requirements.
With caution. Jewelfish are territorially aggressive, especially during breeding. They are best kept with other robust, similarly-sized fish or in a species-only tank.
The name derives from the fish's vivid, iridescent body colours (often red, green, blue spots) that sparkle like precious gems under aquarium lighting.
No, it is a common name. The formal scientific name for a common species is *Hemichromis bimaculatus*. 'Jewel cichlid' is an equally common alternative.
