Aulonocara mamelela

A Little More Information...

Aulonocara mamelela, also known as Lemon Jake, is a Lake Malawi cichlid valued for its lemon-yellow coloration and typical Aulonocara behavior. It comes from the Tanzanian shore, near Undu Reef, where rocky areas meet sandy stretches. This relatively uncommon aquarium fish benefits from a suitable rock-and-sand layout, alkaline water, and a varied diet. Adult males generally develop the brightest colors, while females remain more subdued. Like many Malawi cichlids, it should be housed with carefully selected tank mates. Its wild origin also makes responsible sourcing and careful breeding especially important for aquarists.

General species description

Aulonocara mamelela is a haplochromine cichlid from Lake Malawi, commonly associated with the Aulonocara group known in the aquarium trade as peacocks. It inhabits rocky areas that give way to sandy stretches, where it searches near the bottom for small organisms. Its main appeal is the combination of lemon-yellow coloration, an elegant body shape, and comparatively calm behavior for an African cichlid. It remains territorial, particularly during breeding. Its aquarium availability is considered uncommon, as it is offered less often than the most popular Aulonocara. Fish sold under this name should be kept separate from very similar forms to reduce unwanted hybridization.

Geographic origin and biotope

The species comes from Lake Malawi, in the Tanzanian part of East Africa. Its reference locality is Undu Reef, a lakeshore area with underwater rock formations and sandy beaches or shelves. As in many parts of the lake, the water is clear, mineral-rich, and alkaline. The biotope provides crevices between rocks for shelter and sandy surfaces where the fish examines the substrate for small organisms. Aquatic vegetation plays a secondary role; the habitat is mainly dominated by rocks, with sparse vegetation in nearby areas. In an aquarium, stable water chemistry and excellent water quality are priorities.

Precise location and local name

The locality associated with Aulonocara mamelela is Undu Reef, on the Tanzanian shore of Lake Malawi. The name Lemon Jake is mainly used in the English-speaking aquarium trade and is not a Tanzanian vernacular name. It refers to the bright yellow coloration seen in males. Geographic origin matters because Aulonocara from different localities may show distinct patterns and colors. To preserve this population’s identity, avoid mixing it with other Aulonocara and keep detailed origin records with breeding groups.

Appearance and physical characteristics

Aulonocara mamelela has a laterally compressed body, a relatively rounded head, and the large fins typical of Aulonocara. Adult males show a dominant lemon-yellow coloration, sometimes highlighted by bluish or darker tones depending on mood, age, and social rank. Females are usually duller, with gray-brown or silvery tones, and may display vertical bars. The fins can show contrasting edges or reflections. Under suitable conditions, adult size reaches approximately 15 cm. As in other peacocks, sensory pores on the head help detect vibrations and prey concealed in the sand.

General diet

In nature, Aulonocara mamelela searches for small invertebrates and other organisms associated with the substrate. It uses its sensory pores to locate prey in the sand, then precisely sucks it up. In aquaria, the diet should consist mainly of high-quality Malawi cichlid pellets, supplemented with suitable frozen foods such as mysis or similar small prey. Small portions offered regularly are preferable to one large meal. Avoid very fatty foods and heavily meat-based preparations intended for large predators. A varied diet supports good condition and helps maintain the male coloration, but it never replaces excellent water quality.

Essential data

• Name of original river: Undu Reef
• Local name used: Lemon Jake in the aquarium trade
• Origin of the scientific name: Aulonocara is the genus name; mamelela is the specific epithet.
• Full-name etymology: Aulonocara is formed from Greek roots associated with a cavity or channel and the head; mamelela is the specific name used for this geographic form.
• Common/vernacular names: Lemon Jake

• Discovery: The full name of the describing person and the year are not included here.
• Maximum adult size: Approximately 15 cm
• Water temperature and pH: 24 to 27 °C; pH 7.8 to 8.6
• Appearance of the waterway and surrounding vegetation: Clear, alkaline lake water, rocky relief, sand, and sparse aquatic vegetation.
• Typical tank mates: Labidochromis caeruleus, Copadichromis azureus, Sciaenochromis fryeri
• Temperament and behavior: Territorial but generally moderate for a Malawi cichlid; the male defends a breeding area.
• Water depth: Rocky and sandy shoreline areas.
• Sexual dimorphism: Male more colorful and lemon yellow; female more subdued, often grayish with vertical bars.
• Bottom structure and flow: Rocks, sand, and open areas; lake movement rather than river current.

In your aquarium

To successfully keep Aulonocara mamelela, provide a spacious aquarium with a layout of stable rocks and fine sand, while leaving open areas for swimming. Warm, alkaline, and highly stable water is essential. Use a female-biased social group when keeping a male, and avoid overly aggressive tank mates or other Aulonocara that could hybridize. Because this is a wild-collected species, its geographic origin should be respected and breeding should be planned carefully. Regular water changes, effective filtration, and a balanced diet will support its long-term health and coloration.
