The Brichardi cichlid, scientifically known as Neolamprologus brichardi, belongs to the Cichlidae family. Native to Lake Tanganyika in East Africa, Brichardi cichlids exhibit unique social behaviors and are recognized for their striking appearance and interesting breeding habits. Their genome reflects the diversity of the cichlid family, showcasing adaptations to the specific conditions of their natural habitat.

Brichardi cichlids are characterized by their elongated bodies, vibrant coloration, and extended dorsal fins. In their natural habitat, they form colonies and display intricate social structures. The species is known for its impressive parental care, where both parents actively participate in guarding and raising the fry.

Creating an ideal environment for Brichardi cichlids involves:

- **Tank Size:** A tank of at least 30 gallons for a small group, with more space for larger colonies.
- **Rocky Environment:** Mimic Lake Tanganyika's rocky substrate with caves and crevices for shelter.
- **Water Parameters:** Maintain alkaline water with a pH between 7.8-9.0 and a temperature of 75-80°F (24-27°C).
- **Filtration:** Use efficient filtration to maintain water quality.
- **Substrate:** Fine sand or small-grain gravel to recreate the lake's natural environment.
