Lamprologus cylindricus yellowh. 4 - (Lamprologus cylindricus) — 4-5cm

Overview

The Lamprologus cylindricus, particularly the striking yellowhead variety, is a compact Lake Tanganyika cichlid reaching just 4 cm while delivering bold personality and distinctive yellow head coloration. Requiring a minimum 60-litre aquarium and hard, alkaline Tanganyikan water, this semi-aggressive carnivore suits dedicated keepers seeking authentic East African species in minimal space. Endemic to Lake Tanganyika's rocky shorelines, this cave-spawning species establishes territories and displays fascinating breeding behavior in properly structured aquariums. Available for sale UK from Tropical Fish Co, this freshwater aquarium fish represents one of the smallest yet most visually distinctive Tanganyikan species, perfect for aquarists seeking genuine Lake Tanganyika character in compact dimensions with the bonus of striking yellow head coloration distinguishing it from other small Lamprologus species.

Appearance

Lamprologus cylindricus displays the characteristic yellowhead coloration that makes this variety particularly sought-after, with vibrant yellow coloring on the head region contrasting beautifully against the body's tan to grey base tones. The cylindrical, elongate body plan—referenced in the scientific name—reflects adaptations for maneuvering through tight spaces between rocks. Males may show slightly more intense yellow coloration and marginally larger size than females, though sexual dimorphism remains subtle. The remarkably small 4 cm adult size combined with striking yellow head creates charming yet distinctive presence—among the most visually recognizable small Tanganyikan cichlids. While the body shows relatively subdued coloration, the bright yellow head creates immediate visual impact and aids species identification, making this variety particularly popular among Tanganyikan enthusiasts seeking colorful compact species.

Natural Habitat

Endemic to Lake Tanganyika in East Africa, Lamprologus cylindricus inhabits rocky shoreline zones where complex boulder formations create countless caves and crevices scaled perfectly for this tiny species. The lake's unique chemistry—pH 7.5-8.5, very hard water, exceptional clarity, and stable temperatures of 24-27°C—has driven extraordinary cichlid diversity. This species' exceptionally small adult size allows exploitation of the tightest spaces between rocks inaccessible to larger cichlids, reducing competition while providing secure breeding sites. The species establishes territories centered on preferred caves where it shelters, spawns, and feeds on small invertebrates and zooplankton. The yellowhead variety likely represents a specific geographic population or color morph, though all L. cylindricus share the same specialized cave-dwelling lifestyle requiring replication in aquarium settings.

Aquarium Setup

A 60-litre aquarium provides adequate space for a pair or small group of Lamprologus cylindricus—remarkably modest requirements making this species ideal for aquarists with space limitations. Create authentic Tanganyikan rocky biotope using rocks stacked to form multiple tiny caves and crevices scaled for 4 cm fish. Provide more territories than fish to reduce competition. Fine sand substrate mimics natural environment. Avoid plants as they're inconsistent with Tanganyika biotopes. Install efficient filtration providing 6-8x tank volume turnover per hour to maintain exceptionally high water quality Tanganyikan cichlids require. Despite tiny size, provide stable secure rockwork—this species' bold behavior means it regularly patrols and defends substantial areas relative to body size.

Water Parameters

Replicating Lake Tanganyika's specialized chemistry is essential. Maintain pH between 7.5-8.5 using alkaline buffering substrates preventing pH drops. Water hardness must be very high (12-20 dGH). Temperature stable within 24-27°C. Weekly 25-30% water changes control nitrates below 40 mg/L while maintaining stable alkalinity. Ammonia and nitrite always 0 ppm. Tiny individual size means minimal bioload, but water quality standards remain exacting—Tanganyikan cichlids evolved in pristine conditions tolerating organic accumulation poorly.

Feeding

As dedicated carnivore, requires protein-rich nutrition. Exceptionally small size necessitates very small foods—micro-pellets or crushed pellets, supplemented with baby brine shrimp, daphnia, cyclops, and tiny invertebrates. Avoid overfeeding. Feed 3-4 small portions daily ensuring complete consumption. Use plant matter only as occasional dietary fiber—not primary requirement for carnivorous species. Tiny mouth and high metabolism mean frequent small feedings better than large infrequent meals.

Behaviour

Despite 4 cm size, displays bold territorial behavior defending caves against conspecifics and cave-dwellers. Semi-aggressive—surprisingly assertive, readily confronting larger fish near defended caves. Demonstrates intelligence, learns feeding schedules. Spends time monitoring from cave entrances, investigating food, watching threats. Combination of tiny size, striking yellow head, and bold confidence creates endlessly amusing observation.

Tank Mates

Compatible: other small Tanganyikan cichlids in well-structured tanks. Shell-dwelling Lamprologus, small Julidochromis. Small Synodontis if space allows. Avoid: small peaceful fish (harassed), aggressive cichlids (injury risk), fin-nippers, soft-water species (complete incompatibility).

Breeding

Cave spawner with pairs defending territories and spawning in tightest shelters. Provide numerous tiny caves. Parents guard eggs, fry becoming free-swimming week post-hatch. Extremely small fry require infusoria initially, progressing to baby brine shrimp. Demands exceptional water quality and specialized foods.
