What does chromide mean?
A chromide is a fish belonging to the family Cichlidae — the diverse group of mostly freshwater, spiny-rayed fishes known to most aquarists simply as cichlids. The family encompasses familiar species such as tilapia, angelfish, oscars, and discus, and is famed for the vivid colors and remarkable parental care of its members, many of which guard or even mouth-brood their young. The word derives ultimately from the Greek 'chromis', a name for a fish mentioned in ancient Greek literature, and entered English natural-history vocabulary in the nineteenth century when zoologists were formalizing fish taxonomy. Today 'chromide' is encountered mainly in older scientific texts and specialist aquarium literature, having largely given way to the simpler, more general term 'cichlid'. It is therefore a useful word for readers of classic zoological works, though modern references rarely use it.

Etymology of chromide
The word 'chromide' descends from the Greek 'chromis', the classical name of a fish referred to by Homer and later authors, which naturalists applied to this family of fishes. The suffix '-ide' reflects the standard taxonomic ending associated with a family-level group (the Cichlidae). The term became established in English zoological writing during the nineteenth century, when formal fish classification flourished, and shares its root with related names such as 'chromis'.
How chromide is actually used
A technical or hobbyist term used chiefly in ichthyology and among aquarium keepers. In modern usage the broader word 'cichlid' has largely displaced it, so 'chromide' now reads as somewhat dated or specialist.
Easily confused with chromide
Cichlid refers to the same family of fishes generally, while chromide is an older, more specific term for a member of that family.
