Lamprologus cylindricus 7 - (Neolamprologus cylindricus) — 7-9cm

Overview

Neolamprologus cylindricus is a striking tropical fish UK favourite and a true gem among Lake Tanganyika cichlids. This cave-spawning species is endemic to the southeastern part of Lake Tanganyika, where it inhabits rocky substrates and substrate recesses, feeding on small benthic invertebrates. Reaching a modest 5.5cm in adult size, this compact cichlid is well-suited to aquariums of at least 75 litres and thrives in hard, alkaline water conditions typical of East African rift lakes. Available to buy tropical fish online UK, Neolamprologus cylindricus offers fascinating bottom-dwelling behaviour, striking coloration, and manageable care for dedicated African cichlid enthusiasts.

Appearance

Neolamprologus cylindricus is an elegant, elongated cichlid with a streamlined body and subtle, natural coloration. The body is typically tan to grey with darker vertical bars or blotches that vary in intensity depending on mood and breeding condition. The fins are edged with subtle iridescence, and males may develop slightly more intense coloration and larger size than females. The eyes are large and expressive, reflecting the fish's intelligence and awareness. Overall, this species displays understated beauty that fits perfectly into naturalistic Tanganyikan biotope setups, where its behaviour and personality take centre stage.

Natural Habitat

Endemic to the southeastern part of Lake Tanganyika in East Africa, Neolamprologus cylindricus inhabits rocky substrates and substrate recesses where it feeds on small benthic invertebrates. Lake Tanganyika is one of the world's oldest and deepest lakes, renowned for its hard, alkaline water, high mineral content, and exceptional water clarity. In the wild, this species keeps close to the rocky bottom, hiding in crevices and caves during the day and emerging to forage for food. The lake's stable water chemistry and complex microhabitats have allowed hundreds of cichlid species to evolve, each adapted to specific ecological niches. Replicating these conditions in the aquarium is essential for the health and vitality of Tanganyikan cichlids.

Aquarium Setup

A minimum tank size of 75 litres is suitable for a pair of Neolamprologus cylindricus, though larger tanks provide more stable conditions and reduce aggression. Use a substrate of fine sand to allow natural foraging behaviour, and create a rockscape with plenty of tight crevices, caves, and overhangs to provide hiding places and spawning sites. Include some open swimming areas and ensure the rockwork is stable and securely placed. Filtration must be excellent to maintain pristine water quality, with weekly water changes of 25-30% recommended. Use hard, alkaline water (pH 7.8-9.0) and consider adding Tanganyikan-specific buffering products if your tap water is too soft. Subdued lighting and a dark substrate will reduce stress and encourage natural behaviour. Avoid soft-water setups, as these fish require high pH and hardness to thrive.

Feeding

Neolamprologus cylindricus are primarily carnivorous, feeding on small benthic invertebrates in the wild. In the aquarium, offer a varied diet of small meaty foods such as quality cichlid pellets, frozen or live brine shrimp, mysis shrimp, daphnia, and other small invertebrate foods. Feed twice daily in small portions that can be consumed within a few minutes, and avoid overfeeding, which can lead to water quality issues. A balanced, protein-rich diet will support health, enhance coloration, and encourage natural foraging behaviour. Ensure food reaches the bottom where these fish spend most of their time.

Behaviour

Neolamprologus cylindricus are shy, retiring fish that spend much of their time hiding in crevices and caves, emerging to forage for food. They are intelligent and may learn to recognise their keeper, though they remain cautious and retiring compared to more boisterous cichlids. Pairs form strong bonds and may become territorial, especially during breeding. Despite their shy nature, they are fascinating to observe as they navigate tight spaces and explore their rocky environment. Their deliberate, careful movements and preference for substrate recesses make them a unique addition to Tanganyikan biotope aquariums.

Tank Mates

Choose tankmates carefully to avoid conflicts and ensure harmony. Suitable companions include other small Tanganyikan cichlids of similar size and temperament, Synodontis species (of appropriate size, in larger tanks), and other non-aggressive Tanganyikan species with careful space and territory management. Avoid small timid fish, very aggressive large cichlids, fin-nipping species, soft-water community fish, and tiny invertebrates that may be eaten. The key to success is maintaining a well-structured tank with adequate territories and ensuring all tankmates can handle the semi-aggressive nature of Tanganyika fish. This species is not suitable for typical community tanks but thrives in a dedicated Lake Tanganyika setup.

Breeding

Neolamprologus cylindricus are cave-spawning Tanganyikan cichlids that will usually form a pair and lay eggs in a sheltered recess or cave. Provide rockwork with tight crevices, stable water chemistry, and a quiet tank to encourage breeding. The female lays a small number of eggs, and both parents guard and care for the eggs and fry. Fry can be raised on newly hatched brine shrimp and finely crushed flakes once free-swimming. The parents may become more aggressive during breeding, so ensure tankmates can handle increased territorial behaviour. Breeding Lake Tanganyika cichlids for sale is a rewarding challenge that showcases the fascinating parental care strategies of these species.
