Short Description

Neolamprologus helianthus is a colorful cichlid species from Lake Tanganyika, known for its vibrant yellow body and bold territorial behavior. Though small in size (usually 5–6 cm), these fish can be surprisingly assertive, especially toward smaller tankmates. They are best kept in species-only or Tanganyika-specific setups with plenty of rocks and hiding spaces. This species is suitable for aquarists with some experience in African cichlid care.

Origin

This species is native to Africa, specifically Lake Tanganyika, where it inhabits rocky shorelines and uses crevices for shelter and breeding.

Usual Place in the Tank

Neolamprologus helianthus typically swims in the middle levels of the aquarium but frequently explores rocky structures and hiding spots.

Water Parameters

• Temperature: 23–26 °C (73.4–78.8 °F)
• pH range: 7.0–8.0
• Hardness (dGH): 7–25 °N (125–446 ppm)

Food and Feeding

In the wild, these fish are algae grazers. Their diet should consist mainly of algae-based flakes or spirulina flakes, supplemented with high-quality cichlid pellets. Offer live or frozen treats such as brine shrimp at least twice per week to support coloration and conditioning, especially before breeding.

Temperament and Tankmates

Toward their own species, Neolamprologus helianthus is generally peaceful, especially in established pairs or groups with defined territories. Toward other fish species, however, they can be aggressive, especially toward smaller or similarly shaped fish. Suitable tankmates include other Tanganyika cichlids that can defend themselves, such as Julidochromis or Altolamprologus species.

Sexing

Males tend to grow slightly larger than females, but visual differences are otherwise minimal. Behavioral observation during breeding can help distinguish sexes.

Breeding

This species reproduces through spawning. For successful breeding, provide a tank with rocks, caves, or shells that mimic their natural spawning sites. A sandy substrate is preferred. The female will choose a secluded area, often out of sight, to lay her eggs. After spawning, she will guard and hide the fry. To feed the developing young, introduce newly hatched brine shrimp directly into the breeding site using a pipette or syringe.

Lifespan

The typical lifespan of Neolamprologus helianthus is 5 to 8 years under good aquarium conditions.
