The Princess of Burundi is a graceful Lake Tanganyika cichlid famous for its cooperative breeding system and elegantly trailing fin extensions.
Overview
The Princess of Burundi (Neolamprologus brichardi) is one of the most recognizable and popular cichlids from Lake Tanganyika. This elegant fish captivates aquarists with its refined appearance: a slender body in a delicate beige-cream hue with pearlescent shimmer, graceful lyrate fins with elongated filamentous extensions, and a distinctive blue marking on the gill cover. Adults reach a size of 8-10 cm.
However, the most remarkable feature of N. brichardi is not its looks but its behavior. These fish form complex family colonies with a cooperative breeding system, where older generations of fry assist their parents in guarding and raising younger siblings. This social organization, often described as a "princess hierarchy," is unique among aquarium fish and makes observing a colony an endlessly fascinating experience. Their closest relative is Neolamprologus pulcher, which shares a similar social structure.
Tank Requirements
A group of Neolamprologus brichardi requires an aquarium of at least 100 liters. However, if you plan to observe a full colony forming, it is better to start with 150-200 liters, given that these fish breed prolifically. Water parameters should match Lake Tanganyika conditions: temperature 24-26°C, pH 7.8-9.0, and GH 10-20.
Aquascaping plays a crucial role. Create numerous shelters from rocks, forming grottos, crevices, and caves. Each pair will claim its own shelter, so more hiding spots mean fewer conflicts. Fine sand works best as substrate, replicating the Tanganyika lakebed. Hardy plants like Anubias and Vallisneria can be added, but rocks should form the backbone of the decor. Strong filtration and aeration are essential, as these fish are sensitive to water quality.
Feeding and Diet
In the wild, N. brichardi feeds on small invertebrates and zooplankton, picking food from rocky surfaces. In the aquarium, they are undemanding eaters that readily accept a variety of foods. The staple diet can consist of high-quality flakes or fine cichlid pellets. Be sure to supplement with live or frozen foods: brine shrimp, daphnia, cyclops, and small bloodworms.
Feed two to three times daily in small portions — fish should consume all food within 2-3 minutes. A varied diet supports overall health, enhances the pearlescent sheen, and promotes successful breeding. Avoid overfeeding, as leftover food rapidly degrades water quality, and Tanganyika cichlids are particularly sensitive to elevated nitrate levels.
Care and Maintenance
Stability of water parameters is the cardinal rule for keeping the Princess of Burundi. Weekly water changes of 20-25% are mandatory. Use a gravel vacuum to clean the substrate of food debris, especially in hard-to-reach areas between rocks. Regularly test ammonia, nitrite, and nitrate levels — nitrates should ideally be kept below 20 mg/l.
Filtration should be powerful yet produce minimal current, as N. brichardi inhabits relatively calm rocky zones in its natural habitat. An external canister filter is the optimal choice. Monitor the temperature closely: sudden fluctuations can trigger stress and disease. With proper care, these fish live 8-10 years and reward their keeper with active, engaging behavior throughout their lives.
Compatibility
Neolamprologus brichardi is a relatively peaceful cichlid, but during spawning and fry-rearing periods, pairs become territorial and may actively chase neighbors away from their claimed area. In a species-only tank, a colony is most impressive: dozens of fish of varying ages create a vibrant, dynamic scene.
When keeping them in a community setup, choose tankmates from Tanganyika species that occupy different ecological niches. Excellent companions include shell-dwelling Lamprologus ocellatus, which stay near the bottom, or Neolamprologus leleupi, which prefer different zones of the aquarium. Neolamprologus caudopunctatus is another good option as a peaceful, compact neighbor. Avoid large aggressive cichlids and slow-moving fish with flowing fins, as they may become targets of harassment.
Breeding
Breeding N. brichardi is one of the most rewarding experiences in the aquarium hobby. These fish reproduce readily, and given suitable conditions, a colony forms almost on its own. A pair deposits eggs in a cave or crevice, typically 50 to 200 eggs per spawn. Incubation takes about 3 days at 25°C, and the fry become free-swimming after another 5-7 days.
The truly remarkable phase begins once the fry appear. Unlike most cichlids, juvenile N. brichardi from previous broods are not driven away but remain within the family group, actively helping their parents guard the next generation. This creates a multi-layered "family hierarchy": the breeding pair, older "helpers," and young fry. This cooperative breeding system is a rarity among aquarium fish and has been the subject of extensive scientific research. First foods for the fry include baby brine shrimp and microworms. It is important to manage colony size by regularly removing juveniles, as overcrowding is otherwise inevitable.
