Cincelichthys bocourti

A Little More Information...

Cincelichthys bocourti, also called Golden Mojarra, is a large Central American cichlid valued for its golden coloration and assertive personality. Associated with the Rio Moho in Belize, this species inhabits fresh water where it searches the bottom for food. Its robust body, extended fins and yellow-gold tones become especially impressive in mature adults. With a rarity rating of 2 out of 3, it is less common than many large cichlids offered in the aquarium trade. It nevertheless requires a spacious aquarium, strong filtration and carefully selected tankmates, especially when a pair forms or begins breeding. A stable environment is essential for long-term success.

General species description

Cincelichthys bocourti is a large cichlid with a deep, strongly built body. It belongs to a group of Central American cichlids that were formerly often associated with the genera Vieja or Cichlasoma. Its behavior combines curiosity, territoriality and a strong ability to adapt to its surroundings. In an aquarium, it regularly examines the décor, may move substrate and can defend an area from similar-sized fish or conspecifics. Adults require considerable bottom space and a visual structure made of rocks, roots and sturdy shelters. Territorial behavior usually increases during breeding, so natural sight breaks are useful and overcrowding should be avoided. Despite its assertive nature, it can become familiar with its keeper and readily accept offered food. Its intermediate rarity in the trade makes it appealing to keepers of large American cichlids. A very large aquarium and stable water quality are essential over time.

Geographic origin and biotope

The range associated with Cincelichthys bocourti lies in Central America, particularly Belize, in the Rio Moho basin. It inhabits warm fresh water, often in calm or moderately flowing areas where the bottom provides feeding surfaces and shelter. The natural habitat includes vegetated banks, submerged roots and areas of fine or gravelly substrate. Light levels may vary according to bank vegetation and stream width. Like several large cichlids from this region, it benefits from well-oxygenated water and low organic waste accumulation. In captivity, these conditions can be approximated with oversized filtration, moderate water movement and regular water changes. Delicate plants may be uprooted or chewed, so tough species and plants attached to décor are better choices. The hardscape must remain stable because substrate-moving behavior can be significant. The Rio Moho basin is the principal geographic and ecological reference for this population.

Precise location and local name

The reference locality supplied for Cincelichthys bocourti is the Rio Moho in Belize, a river in the southern part of the country that crosses a tropical region before joining the coastal drainage network. In the English-speaking aquarium trade, the name Golden Mojarra is commonly used. Mojarra is a vernacular term applied to several Central American cichlids and is not, by itself, a precise scientific name. The species may also be listed only by its Latin name, particularly among specialized aquarists. Geographic information is valuable because large Central American cichlids can show differences in coloration and behavior according to their origin. To maintain a correctly identified population, it is preferable to keep collection or strain information when purchasing fish. In the aquarium, geographic origin also helps guide suitable water parameters and tankmates from a similar ecological context. Golden Mojarra remains the most useful common name in English-language catalogues.

Appearance and physical characteristics

Cincelichthys bocourti has a tall, powerful and laterally compressed body typical of a large territorial cichlid. Adult coloration generally ranges from golden yellow to olive, with darker markings that can change according to mood, age and social conditions. The dorsal and anal fins are elongated and carry rays that emphasize the fish’s profile. The head is relatively broad, the mouth is well developed and the jaws are suited to taking varied foods and moving small elements of the décor. Color may fade after transport, during acclimation or under intimidation, then intensify under good conditions. Mature males are often larger and more robust; they may also show stronger contrast and a nuchal hump, although these traits do not always allow reliable sexing. Females may become darker while guarding eggs or fry. The robust golden body remains the most distinctive visual feature of this species.

General diet

In nature, Cincelichthys bocourti has an opportunistic diet that includes invertebrates, small aquatic organisms, plant matter and organic debris associated with the substrate. In aquaria, the staple should be a complete, high-quality food designed for large cichlids and offered in portions appropriate for the fish’s size. Sinking or slow-sinking pellets help reproduce its bottom-exploring feeding behavior. Frozen foods such as shrimp, krill or aquatic larvae can be used as supplements, but should not make up the entire diet. Regular plant matter, supplied through spirulina foods, vegetable pellets or suitably prepared vegetables, helps provide variety. Young fish should receive smaller, more frequent meals, while adults can generally be fed once or twice daily according to their condition. Remove leftovers because this species produces a substantial organic load. Live foods from uncertain sources should be avoided. A varied, moderate diet supports growth, coloration and good body condition.

Essential data

• Native river: Rio Moho
• Local name used: Golden Mojarra
• Origin of the scientific name: The genus combines the idea of “cincel,” or chisel, with the Greek ichthys, fish; bocourti honors naturalist Marie-Firmin Bocourt.
• Etymology of the full name: Cincelichthys essentially means “chisel fish”; bocourti commemorates Bocourt.
• Common/vernacular names: Golden Mojarra
• Family: Cichlidae
• Subfamily: Cichlinae
• Name pronunciation: sin-sell-ikth-iss boh-kor-tee
• Discovery: Albert Karl Ludwig Gotthilf Günther, 1860
• Maximum adult size: About 30 cm
• Water temperature and pH: 24 to 28 °C; pH 7.0 to 8.2
• Stream appearance and surrounding vegetation: Tropical stream with variable flow, vegetated banks, submerged roots and natural substrate.
• Typical tankmates: Cincelichthys pearsei, Chuco godmanni, Petenia splendida, Parachromis friedrichsthalii, Thorichthys meeki
• Temperament and behavior: Active, territorial and generally more aggressive during breeding.
• Water depth: Shallow to moderately deep sections of the river.
• Sexual dimorphism: Males are often larger and more robust; coloration and nuchal hump may be more pronounced.
• Bottom structure and flow: Sand, gravel and natural debris; low to moderate flow depending on the section.

In your aquarium, provide a very spacious tank, powerful filtration and firmly anchored décor. Keep the water clean, offer a varied diet and monitor interactions between adults. Fragile plants are rarely durable with this large cichlid, which may dig and rearrange the substrate. Tankmates should be chosen carefully, with preference given to robust, similarly sized fish able to tolerate some territorial behavior. Gradual acclimation and regular water changes will help preserve its golden coloration and vitality. Available space and social stability are the two most important factors for successfully keeping this species.
