Cylindricus Cichlid

Neolamprologus cylindricus

📍 Lake Tanganyika

Neolamprologus cylindricus is a small, elongated cichlid endemic to Lake Tanganyika, known for its slender body shape and subtle coloration. These fish are relatively peaceful compared to other Tanganyikan cichlids and make excellent additions to species-specific or carefully planned community tanks. They are bottom-dwellers that appreciate rocky substrates and caves for shelter and breeding.

Care Guide

Diet

Feed small carnivorous foods such as bloodworms, brine shrimp, and quality micro pellets 2-3 times daily. Cylindricus cichlids are micropredators that feed on small invertebrates in their natural habitat. Occasional live food offerings help maintain natural feeding behaviors and coloration.

Behavior

Cylindricus cichlids are relatively peaceful but territorial, especially during breeding. They spend most of their time near the substrate and rocky structures, foraging and exploring caves. Males may display aggression toward conspecifics and similar-sized fish, but they are less aggressive than many other Tanganyikan cichlids.

Breeding

These fish are cave spawners that require rocky structures and caves for successful breeding. Pairs are monogamous and will defend their breeding territory vigorously. Fry are relatively large and can be fed micro foods immediately after becoming free-swimming.
