Aulonocara cobue

A Little More Information...

Aulonocara cobue, also called Chitimba, is a Lake Malawi cichlid valued for its coloration and its characteristic bottom-searching behavior. Native to the northwestern part of the lake in Mozambique, it inhabits areas where rocks alternate with sandy sections. Like other Aulonocara, it detects prey with sensory pores located beneath the head. Its availability in the hobby is moderate: it is less common than the most popular varieties, yet it remains sought after by aquarists who want to maintain a geographically identified population.

General species description

Aulonocara cobue belongs to the group commonly known as Malawi peacocks, cichlids adapted to mixed sandy and rocky bottoms. It spends much of its time inspecting the substrate, often making precise head movements to locate small organisms buried in the sand. Adult males generally develop brighter colors than females and become more territorial during breeding. In the aquarium, this species requires a structured layout, alkaline water, and effective filtration. It is better suited to a Lake Malawi cichlid aquarium than to a typical tropical community aquarium.

Geographic origin and biotope

Aulonocara cobue originates from Mozambique, in the northern Lake Malawi area associated with Cobue on the western shore. Its natural habitat includes rocky shorelines, boulder fields, and sandy beaches where the water remains clear and mineral-rich. The bottom provides crevices for shelter, while sandy surfaces are used for feeding. Aquatic vegetation is generally limited; the surrounding landscape is mostly made up of rocky or sandy shores and terrestrial vegetation that varies from sparse to moderate depending on the site.

Precise location and local name

This geographic form is associated with Cobue, a locality on the Mozambican shore of Lake Malawi in the northern part of the basin. Chitimba is used as a common or vernacular name in the aquarium trade. Geographic origin matters because Lake Malawi Aulonocara populations may differ in color and should not be mixed carelessly. To preserve the identity of the strain, it is best to keep fish from the same locality and avoid crossing them with other Aulonocara.

Appearance and physical characteristics

Aulonocara cobue has a relatively deep, laterally compressed body, with large dorsal and anal fins. Mature males usually show a blue to blue-violet base color enhanced by metallic tones and contrasting fin patterns; intensity varies with age, social rank, and the origin of the strain. Females are plainer, often grayish brown to silvery, with more visible vertical bars. Like other Aulonocara, the species has sensory pores beneath the head that help it detect the movements of small prey in the sand.

General diet

In the wild, Aulonocara cobue mainly searches for small invertebrates and other organisms living in the substrate. In the aquarium, its diet should focus on quality foods based on marine proteins or invertebrates, supplemented with a vegetable component. Malawi cichlid pellets or flakes can form the staple diet, with frozen foods offered in moderate portions. Avoid overfeeding and very fatty foods. A varied diet given in small amounts supports growth and helps maintain good digestive condition.

In your aquarium

To successfully keep Aulonocara cobue, provide a spacious aquarium, stable alkaline and well-oxygenated water, and a rocky layout with open swimming space and sandy areas. A community made up of compatible species with distinct color patterns helps reduce tension and the risk of hybridization. Feed moderately and maintain the filtration regularly. Stable water parameters, respect for geographic origin, and effective territory management are the most important factors for keeping healthy, well-colored fish.
