Cyphotilapia frontosa sp. Black Widow

A Little More Information...

Cyphotilapia frontosa sp. Black Widow is an aquarium trade form sold under a name that highlights its dark coloration. It belongs to the frontosa group from Lake Tanganyika, large African cichlids adapted to alkaline, mineral-rich water. Its massive body, forehead hump, and vertical bars make it immediately recognizable. The name Black Widow mainly refers to a dark-looking selection rather than a separate species. Like other frontosas, it requires a spacious aquarium, stable water, and carefully chosen tank mates because growth is slow, while adult size eventually becomes substantial.

General species description

Cyphotilapia frontosa sp. Black Widow is an aquarium name associated with Cichlidae and the species Cyphotilapia frontosa. The name Black Widow is used for fish showing a particularly dark coloration, while the underlying body shape remains that of frontosa: a tall body, large head, and increasingly pronounced forehead hump in adults. This is a schooling cichlid commonly kept in groups, forming a hierarchy without being as constantly aggressive as several similarly sized African cichlids. Growth is gradual, and successful care requires a large, well-filtered aquarium with a stable rock structure.

Geographic origin and biotope

Geographic origin and countries of reference: Tanzania, Burundi, the Democratic Republic of the Congo, and Zambia. The species is endemic to Lake Tanganyika, one of the great lakes of the Rift Valley. It mainly occupies rocky shoreline areas and deeper zones where the water is clear, alkaline, and highly mineralized. The natural habitat has little dense aquatic vegetation; shelter is mostly provided by boulders, crevices, and rock piles. In the aquarium, hard alkaline water is more important than a heavily planted layout.

Precise location and local name

The commercial population called Black Widow is sold under this name in the aquarium trade. The most common hobby name for the species remains frontosa, sometimes followed by a locality name when a geographic strain is identified. This designation should not be confused with the commercial localities Moba or Kipili, which are other frontosa designations used in the hobby. For aquarists, the most useful considerations are the stated strain, expected adult size, and compatibility with other Tanganyika fishes.

Appearance and physical characteristics

Cyphotilapia frontosa sp. Black Widow has a tall, sturdy, laterally compressed body. The head becomes imposing with age, and the forehead hump is one of the most striking adult features. Typical frontosa show dark vertical bands over a gray-blue background; in the Black Widow form, the overall appearance is often much darker. The dorsal and anal fins are extended, and the broad mouth is suited to taking prey. Body size and head shape are the most noticeable traits, with a massive profile that requires a deep, spacious aquarium.

General diet

In nature, Cyphotilapia frontosa mainly eats small fish and other animal prey available in its deep habitat. In the aquarium, its diet should be protein-rich but varied, using quality pellets for large cichlids, suitable frozen foods, and measured portions. Meals should remain moderate to prevent obesity and unnecessary water pollution. A consistent feeding routine without excess supports balanced growth and good condition. Avoid live prey from questionable sources and favor foods that can be controlled easily, offered in small quantities.

Essential data

• Native river name: Lake Tanganyika; this is a lake-dwelling species.
• Local name used: frontosa; Black Widow is a trade name.
• Origin of the scientific name: the genus name is built from Greek terms associated with a hump and the historical tilapia group; frontosa refers to the prominent forehead.
• Full-name etymology: Cyphotilapia refers to the forehead hump and historical affinity with tilapias; frontosa means broad-fronted or foreheaded; Black Widow describes the dark color selection.
• Common/vernacular names: frontosa, Tanganyika frontosa, black widow frontosa.
• Family: Cichlidae.
• Subfamily: Pseudocrenilabrinae.
• Name pronunciation: sigh-foe-tih-LAH-pee-ah fron-TOH-sah.
• Discovery: George Albert Boulenger, 1906.
• Maximum adult size: about 35 cm.
• Water temperature and pH: 24 to 27 °C; pH about 8.6 to 9.2.
• Appearance of the waterway and surrounding vegetation: large lake with clear, alkaline, mineral-rich water; rocky shores and sparse aquatic vegetation.
• Typical tank mates: Cyphotilapia frontosa Moba, Cyphotilapia frontosa Kipili, Synodontis multipunctatus, Altolamprologus compressiceps, Neolamprologus leleupi.
• Temperament and behavior: generally calm to moderately territorial, schooling, hierarchical, and predatory toward small fish.
• Water depth: deep rocky areas, often several dozen metres deep.
• Sexual dimorphism: males are usually larger, with a more developed forehead hump; sexing young fish can be difficult.
• Bottom structure and flow: rocky bottom, crevices, and rock piles; lacustrine water with low natural movement but strong aquarium filtration.

In your aquarium

To succeed with Cyphotilapia frontosa sp. Black Widow, provide a very spacious aquarium, powerful filtration, and a rock layout built on firmly placed structures. Keep the water warm, hard, and alkaline, and perform regular water changes. A stable group helps limit tension, while very small tank mates may be treated as prey. Success depends on available volume, stable parameters, and controlled feeding. This form is commonly encountered in the specialist Tanganyika cichlid trade, so focus on selecting healthy fish and learning the background of the strain offered.
