Daffodil Cichlid (Neolamprologus pulcher) Care Guide
Neolamprologus pulcher is a Lake Tanganyika cichlid famous for cooperative breeding, in which groups of helpers assist a single pair in raising fry.
Compiled by Aquairi from published sources · Published · Updated
Overview
Neolamprologus pulcher, the Daffodil cichlid, is a yellow-finned rock-dweller endemic to Lake Tanganyika. It belongs to the brichardi group; N. pulcher and the former N. brichardi are now treated as the same species, with pulcher the valid name. The species is a model organism for the study of cooperative breeding in fish.
Taxonomy
- Family: Cichlidae
- Genus: Neolamprologus
- Scientific name: Neolamprologus pulcher
- Common synonyms: Neolamprologus brichardi
Habitat
The species inhabits rocky coastlines in the southern portion of Lake Tanganyika across Burundi, the Democratic Republic of the Congo, Tanzania and Zambia. Wikipedia reports it occurs at depths of at least 10 metres in sediment-rich areas; FishBase gives a typical range of about 6-12 metres.
Tank requirements
- Minimum tank volume: 250 L (66 gal)
- Temperature: 24-27 °C (75-81 °F)
- pH: 8.5-9.2
- GH: 12-25 °dGH
- Rockwork with caves and crevices for spawning
- Lifespan: 8-12 years
Stacked rockwork that creates caves suits colony formation. FishBase lists a wild temperature of about 24-26 °C; the parameters above follow the verified care record.
Diet
FishBase rates the species as omnivorous with a trophic level near 3.4. In the wild it picks plankton from the water column along with small crustaceans and invertebrates. In the aquarium it accepts small frozen and prepared foods fed about twice daily.
Compatibility
Semi-aggressive and mid-water in habit, it forms colonies that defend a shared territory. Suitable companions include open-water Cyprichromis, Julidochromis and Synodontis petricola. Avoid mbuna and Tropheus, whose differing temperaments and diets clash with Tanganyikan rock-dwellers.
Breeding
Pairs are monogamous cave-spawners. Wikipedia describes permanent social groups of one breeding pair plus helpers of both sexes (commonly 1-14 helpers) that provide brood care and raise offspring survival. FishBase notes clutches of roughly 20-60 eggs laid in crevices, with both sexes and larger juveniles defending the nest.
Conservation status
IUCN Red List: Least Concern (assessed 2025), per FishBase.
Breeding Neolamprologus pulcher (Daffodil Cichlid)
Overview
Neolamprologus pulcher, the Daffodil Cichlid, is endemic to the southern rocky coastlines of Lake Tanganyika, recorded from Burundi, the Democratic Republic of Congo, Tanzania and Zambia at depths of around 10 m or deeper. It is a cooperative breeder: groups consist of one breeding pair plus helpers of both sexes, typically with 1-14 helpers depending on territory size, with larger groups holding larger territories. According to FishBase, pairs remain together until one partner dies.
Sexing
Both sexes show extended fin filaments and are similar in appearance, making visual sexing difficult. Pairs and colonies are best established by raising a group together and letting the dominant breeding pair emerge within the social hierarchy.
Conditioning
Maintain stable hard, alkaline water. FishBase reports a pH range of about 7.3-8.5 and a temperature of 24-26 C for the species, with occurrence in sediment-rich rocky regions. A varied carnivorous diet keeps the colony in breeding condition.
Breeding Setup
Provide an aquarium with extensive rockwork forming caves and crevices so a colony can establish a defended territory. Because helpers and larger juveniles share territory defence, a colony tank should be spacious enough to accommodate a multi-generation group.
Spawning Behavior & Trigger
The pair spawns in a cave or crevice. FishBase reports clutches of about 20-60 eggs deposited in crevices; egg investment per egg can decrease when more helpers are present. The territory is defended jointly by the male, the female and larger juveniles.
Egg & Fry Care
Care is cooperative. The dominant pair and the helpers protect the offspring, and the presence of helpers reduces fry mortality and can raise overall breeding success, measured as a combination of clutch size and egg survival, compared with pairs lacking helpers. The dominant female performs most of the direct care while the dominant male and helpers contribute to territory and offspring defence. Fry are reared within the colony territory rather than dispersed, so successive broods may share the same group.
Common Challenges
Maintaining a stable hierarchy is key: removing the dominant breeders or crowding the colony disrupts the cooperative structure. Genetic studies of wild groups have shown frequent mixed parentage, with a high rate of young not fathered by the dominant male, so a colony may contain offspring from more than one parent.
