Distribution and habitat
The distribution area of the Cylindricus cichlids is exclusively (endemic) in the southeast of Lake Tanganyika, where they prefer to live near the bottom in the rugged rocky littoral with sandy substrate at 5-10 m depth.
Maintenance
The aquarium should be structured with sturdy rock structures and roots, have numerous caves, crevices and shelters that provide hiding places as well as open areas with a substrate of fine, light sand and adequate swimming space.
No ammonia, ammonium or nitrite should be detectable, and the nitrate value should not exceed 100 mg/l. To ensure the water quality and oxygen content, a filter and heater adapted to the aquarium size is required, as well as lighting for the species-appropriate day-night rhythm of the animals.
Diet
In the wild they feed mainly on small crustaceans and insect larvae. The food supply consists of live, frozen and dry food. For a balanced diet, feed once a day with a high-quality dry food for Tanganyika cichlids (flakes, granules, pellets) as well as cyclops, daphnia, artemia and mosquito larvae (live or frozen)
It is recommended to feed small portions several times a day. Only feed as much as will be eaten within a few minutes. A regular and varied diet promotes health and prevents deficiency symptoms.
Behaviour and compatibility
They should be kept in pairs. Internally they are very territorial and should not be kept with other Neolamprologus. Keeping multiple pairs is only recommended in a much larger and richly structured tank. They can be socialized with other robust Lake Tanganyika cichlids.
Basically, only compatible fish species with similar demands on water condition and water temperature may be socialized.
Sex dimorphism
The sexes are difficult to distinguish. Adult males are slightly larger than the females.
Reproduction and breeding
They are pair-building cave breeders and usually attach the spawn to the cave ceiling or walls. The female performs brood care while the male defends the territory. The fry hatch after 2-3 days and swim free after 6-8 days. They are cared for by the parents for another 1-2 weeks before brood care ends.
Fry must be fed several times a day with special rearing food (Artemia nauplii). In community tanks breeding is hardly possible, because the fry are easy prey.
Important
In its range there are different colored site variants
The well-being of the fish should be checked regularly. Temperature should be checked daily, pH, hardness and nitrate levels at least fortnightly. Regular partial water changes are recommended, even when contaminant levels have not yet reached the upper limit. Sudden changes in water quality should be avoided. Newly introduced fish must be accustomed slowly to the water in the aquarium.
