Geophagus sp. Caqueta

A Little More Information...

Geophagus sp. Caqueta is a South American cichlid still identified under an aquarium or trade name rather than as a formally described species. Its name refers to the Río Caquetá basin in Colombia and places it among the bottom-oriented fish that sift soft substrates. This form remains very rare in the hobby, while the specimens offered are wild collected. As with other eartheaters, its appeal comes from its active behavior, its habit of filtering substrate and its imposing presence in a properly designed regional aquarium.

General species description

Geophagus sp. Caqueta belongs to the eartheater group within the genus Geophagus. The term “sp.” indicates that the fish has been identified at genus level but is being kept under a provisional name. It should therefore not automatically be confused with a described species such as Geophagus altifrons or with another geographic form. Its expected behavior is that of a benthic cichlid that constantly explores the bottom while searching for food. Its rarity level of 3 makes it a fish for experienced aquarists who can provide stable water and careful quarantine for wild-collected specimens.

Geographic origin and biotope

Reference country: Colombia. The name Caqueta refers to the Río Caquetá basin, an important Amazonian drainage in Colombia. Species in the genus Geophagus generally use the bottom areas of rivers and connected waterways, where they sift sediments for small prey and organic matter. In an aquarium, a layout with sandy substrate, regular water movement and shelters made from roots is more suitable than a heavily rocky design. Wild fish benefit from gradual acclimation, clean water and varied food from the time they arrive.

Precise location and local name

The name Caqueta provides a geographic indication linked to the Caquetá basin. On its own, it does not provide a sufficiently precise collection locality to assign a village, tributary or specific site. In the aquarium trade, this form is generally identified by its provisional scientific name, Geophagus sp. Caqueta, or by a descriptive translation such as “Caquetá eartheater.” The latter is not an established vernacular name. To preserve the geographic value of this strain, it is best to keep the original designation and avoid mixing it with other Geophagus from different origins.

Appearance and physical characteristics

Like other members of its genus, Geophagus sp. Caqueta has a laterally compressed body, a downward-oriented mouth and fins suited to life close to the substrate. Its shape is typical of a substrate-sifting cichlid, with a developed dorsal fin and coloration that can change with mood, age and lighting. The exact color pattern of this Caquetá form should not be generalized without reliable information from a defined population. Identification therefore depends more on origin, overall morphology and collection records than on a single spot or color seen in a shop.

General diet

Geophagus sp. Caqueta should receive a varied diet delivered near the bottom. High-quality sinking pellets can form the staple, supplemented with frozen foods such as brine shrimp, mysis and mosquito larvae. Its sifting behavior allows it to inspect sand, but this activity does not replace regular meals. Several small feedings encourage better digestion and reduce leftovers. An excessively rich or exclusively meaty diet may be unsuitable; instead, use a formula containing some plant matter and meals appropriate for an omnivorous benthic cichlid.

Essential data

• Name of the original river: Río Caquetá
• Local name used: Geophagus sp. Caqueta
• Origin of the scientific name: Geophagus is the genus name; “sp.” indicates that no precise species is given; Caqueta refers to Caquetá.
• Meaning of the full name: Geophagus comes from Greek and means “earth eater”; sp. is short for species; Caqueta refers to Caquetá.
• Common/vernacular names: Caquetá eartheater
• Family: Cichlidae
• Subfamily: Cichlinae
• Name pronunciation: jee-oh-fay-gus sp. kuh-kay-TAH
• Discovery:
• Maximum adult size:
• Water temperature and pH: 24 to 28 °C; pH 6.0 to 7.5 in aquaria
• Watercourse appearance and surrounding vegetation: South American watercourse with soft-bottom areas and riparian vegetation
• Typical tankmates:
• Temperament and behavior: generally peaceful, active, social and substrate-sifting; more territorial during spawning
• Water depth:
• Sexual dimorphism: difficult to distinguish in young fish; differences become more apparent in mature breeding fish
• Bottom structure and flow: fine, smooth sand recommended; regular to moderate flow

For greater success

Success with Geophagus sp. Caqueta depends on a spacious aquarium, fine, smooth sand and effective filtration without excessive current. Keep it in a group when aquarium size allows, monitor water quality and provide varied meals. Because this is a wild and very rare fish, quarantine, slow acclimation and preservation of its collection information are especially important. Avoid aggressive or very small tankmates, which may stress it or be swallowed.
