Neolamprologus tretocephalus, commonly known as the Five-bar Cichlid, is a species of cichlid endemic to Lake Tanganyika in East Africa. It is characterized by its distinctive vertical banding pattern and robust body shape. This species is a substrate spawner and exhibits biparental care. It is a popular aquarium fish due to its striking appearance and interesting behavior, though its territorial nature requires careful tankmate selection.
Physical Characteristics
- Body shape
- compressed
- Coloration
- The base body color is typically a light grey to silvery-white, adorned with five prominent, dark, vertical bars that extend from the dorsal fin to the ventral side. The fins are often edged with a light blue or white margin. Some individuals may exhibit iridescent blue or green hues on their scales, particularly on the head and operculum.
- Scale type
- ctenoid
- Mouth position
- terminal
- Distinctive features
- Five distinct dark vertical bars on a light body., Robust, somewhat deep body., Large eyes., Pointed snout.
- Dorsal fin
- Long and continuous, with a spiny anterior portion and a soft-rayed posterior portion. Often edged with a light blue or white band.
- Tail fin
- Truncate to slightly emarginate, often with a light blue or white margin.
- Pectoral fin
- Relatively small and clear.
- Distinctive fins
- Pelvic fins are elongated and often have a bluish tint.
Identification Tips
Vertical Bars
Count the five prominent, dark vertical bars on the body. This is the most distinguishing feature.
Body Shape
Observe the relatively deep and compressed body, typical of many rock-dwelling Tanganyikan cichlids.
Fin Edges
Look for the light blue or white edging on the dorsal, caudal, and sometimes anal fins.
Habitat
- Water type
- freshwater
- Depth
- Typically found in depths ranging from 5 to 30 meters (16 to 98 feet), but can be found deeper.
- Environment
- Rocky littoral zones of Lake Tanganyika, preferring areas with abundant rock formations, caves, and crevices for shelter and breeding. They are often found near the substrate.
- Geographic range
- Endemic to Lake Tanganyika, East Africa. Distributed throughout the lake, but often found in specific rocky habitats.
Aquarium Information
- Care level: intermediate
- Temperament: territorial
- Diet: carnivore
- Minimum tank size: 120 liters (30 gallons) for a single specimen, larger for a pair or community
- Temperature: 23-27 C (73-81 F)
- pH level: 7.8-9.0
- Hardness: 10-20 dGH
- Compatibility: Best kept with other robust Tanganyikan cichlids of similar size and temperament, or as a species-only tank. Avoid small, timid, or long-finned fish. Can be aggressive towards conspecifics, especially during breeding.
- Special requirements: Requires a rocky aquascape with numerous caves and crevices for shelter and breeding sites. A sandy substrate is preferred. Excellent filtration and regular water changes are essential to maintain water quality. Provide ample swimming space.
Wild Information
- Conservation status: least concern
- Seasonality: Breeds year-round in suitable conditions, with peak activity often observed during warmer periods in the lake.
- Market price: Moderate to high, depending on size and origin (wild-caught vs. captive-bred)
- Commercial importance: medium
- Taste: Not typically consumed due to its small size and value as an ornamental fish.
- Texture: Not typically consumed due to its small size and value as an ornamental fish.
- Nutritional value: Not typically consumed due to its small size and value as an ornamental fish.
Key Facts
Parental Carebehavior
Neolamprologus tretocephalus exhibits biparental care, with both male and female guarding the eggs and fry.
Diet in the Wildbehavior
In its natural habitat, the Five-bar Cichlid primarily preys on small invertebrates and crustaceans found among the rocks.
Territorial Naturebehavior
This species is highly territorial, especially when breeding, and will aggressively defend its chosen cave or rock crevice.
Lake Tanganyika Endemicinteresting
Neolamprologus tretocephalus is one of the many fascinating cichlid species found exclusively in the ancient rift lake, Lake Tanganyika.
Safety Information
Handle with care- Safety level: caution
- Venomous: No
- Edibility: not recommended
- Handling notes: While not venomous, like all cichlids, they possess sharp fin spines that can cause minor punctures if handled carelessly. They can also deliver a painful bite if provoked, especially during breeding. Use a net for handling and avoid direct contact with hands.
Similar Species
Marbled Cichlid
Neolamprologus moorii
N. moorii typically has a more mottled or marbled pattern rather than distinct vertical bars, and its body shape can be slightly more elongated. The number and clarity of bars are key differentiators.
Compressiceps Cichlid
Altolamprologus compressiceps
A. compressiceps has an extremely laterally compressed body, much flatter than N. tretocephalus, and a distinctively upturned mouth. While it also has vertical barring, the body morphology is very different.
