Pundamilia nyererei Care Guide
Pundamilia nyererei is a brightly coloured haplochromine cichlid endemic to Lake Victoria, living near rocky shores and brooding eggs in the female's mouth.

Overview
Pundamilia nyererei is a haplochromine cichlid endemic to Lake Victoria, described by Witte-Maas and Witte in 1985 and named after Tanzanian president Julius Nyerere. FishBase places it in the genus Pundamilia. It lives close to rocky shores and islands. Females are reported to prefer brighter, more colourful males during mate choice, a system that drives its vivid male coloration.
Taxonomy
- Family: Cichlidae
- Genus: Pundamilia
- Scientific name: Pundamilia nyererei
- Authors: Witte-Maas & Witte, 1985
- Synonym: Haplochromis nyererei
Habitat
FishBase reports the species occurs in the close vicinity of rocky shores and rocky islands in Lake Victoria at depths of about 1-4 metres. The Victoria basin is warm and alkaline. It is one of several Pundamilia colour forms distributed across the southern part of the lake.
Tank requirements
- Maximum size: about 7.7 cm (3.0 in) SL (FishBase)
- Temperature: 22-28 °C (FishBase)
- pH: 7.5-8.5 (KB record, alkaline Victoria water)
- Rocky aquascape with caves and territories
- Keep one male with several females
Diet
FishBase reports a trophic level of about 2.6 and notes the species feeds on algae and insects, indicating an omnivorous diet. In aquaria a varied diet with vegetable matter suits it.
Compatibility
As a colourful Victorian haplochromine it is best kept as one male with a group of females to spread aggression and prevent hybridisation with related haps. Suitable tankmates are other robust Victorian cichlids and Synodontis catfish; mixing with similarly coloured congeners should be avoided.
Breeding
FishBase confirms maternal mouthbrooding: females incubate the eggs and fry in the mouth. High resilience and a short minimum doubling time indicate frequent reproduction.
Conservation status
IUCN Red List: Least Concern (assessed 2010). Lake Victoria haplochromines as a group have suffered major declines from the introduced Nile perch.
Pundamilia nyererei Breeding Guide
Overview
Pundamilia nyererei is a maternal mouthbrooding haplochromine endemic to the southern portion of Lake Victoria, with at least eleven known populations. The female carries and protects eggs and fry in her mouth. The species is famous as one half of a sympatric sister-species pair with Pundamilia pundamilia, where male nuptial colour drives female mate choice and reproductive isolation. Dominant males show red-yellow on the body with red concentrated on the dorsum.
Sexing
Sexing is straightforward in mature fish: males grow larger and are far more colourful, while females are cryptically coloured. Females, the sole investors in parental care, exhibit strong preferences for males with particular nuptial colouration, which generates directional sexual selection within the species.
Conditioning
Condition the group on a varied omnivore diet to bring females into spawning condition and intensify male colour. Strong male coloration is central to spawning success because mate choice is colour-based.
Breeding Setup
A species tank with a single male and at least three females is recommended, though spawning also occurs in community tanks. Reported breeding parameters are a temperature of 23–27 °C, pH 7.0–8.5 and hardness 72–268 ppm. Provide defined spawning sites among rocks where the male can hold a territory and display.
Spawning Behavior & Trigger
A male defends a spawning site and displays to females. A receptive female deposits eggs and immediately takes them into her mouth. The male's anal fin carries egg-like spots; as the female tries to collect these dummy eggs, the male releases sperm to fertilise the clutch in her mouth. This cycle repeats until spawning is complete.
Egg & Fry Care
The female carries the eggs for around three weeks before releasing free-swimming fry. Newly released fry can take Artemia nauplii, microworm and powdered dry foods. A holding female can be moved to a separate tank to protect the brood and improve survival.
Common Challenges
Keep only one male per group to limit aggression and prevent dull subdominant males. Because females choose mates by colour, keep this species away from closely related red Victorian haps to avoid hybridisation, which is a real risk in this group given ongoing gene flow between sister species in the wild.
