The Long-Nosed Gold-Tip Cichlid (Ophthalmotilapia nasuta) is a striking Lake Tanganyika cichlid for sale UK that captivates aquarists with its distinctive elongated snout and golden fin accents. Endemic to the rocky shorelines of Lake Tanganyika in East Africa, this remarkable species displays fascinating behaviour and stunning coloration that makes it a prized addition to specialized African cichlid aquariums. Males develop particularly intense golden tips on their fins and a pronounced nasal extension that gives this species its common name. As a planktivore in nature, this cichlid occupies a unique ecological niche and requires specific water conditions to thrive in captivity.
Ophthalmotilapia nasuta presents a sleek, laterally compressed body with a dramatically elongated snout that distinguishes it from other Tanganyikan cichlids. Males display spectacular golden-yellow tips on the dorsal and caudal fins, contrasting beautifully against a silvery-blue base coloration. The extended nose gives the fish an elegant profile, perfectly adapted for picking tiny organisms from the water column. Females are generally less colourful but maintain the characteristic long snout. Breeding males intensify their golden accents and may show vertical barring on the flanks. The eye placement and large, upturned mouth reflect this species' specialized feeding strategy in the wild.
This species inhabits the rocky shorelines and intermediate depths of Lake Tanganyika, typically found between 5 and 40 meters where they form loose aggregations over sandy patches adjacent to rocky areas. Males establish small display territories where they perform elaborate courtship dances to attract females. The lake's ancient, stable water chemistry—characterized by high mineral content, alkalinity, and exceptional clarity—has shaped the evolution of this specialized planktivore. Ophthalmotilapia nasuta feeds primarily on zooplankton and tiny invertebrates suspended in the water column, using its protruding snout to precisely target individual prey items.
A spacious aquarium of at least 300 litres is essential for maintaining a group of Long-Nosed Gold-Tip Cichlids. Create a Lake Tanganyika biotope with a substrate of fine sand or small-grain gravel, substantial rockwork arranged to form caves and territorial boundaries, and ample open swimming space in the mid-water region. This species appreciates vertical rock structures but spends considerable time in open water, so balance hardscape with swimming room. Lighting should be bright to moderate, reflecting the clear waters of their natural habitat. Strong water movement and high oxygenation are critical—use powerful filtration and consider supplemental circulation pumps. Avoid soft-water plants; instead, use hardy species like Vallisneria or Anubias that tolerate alkaline conditions, or rely solely on rock décor.
Replicating Lake Tanganyika's stable, hard, alkaline water is non-negotiable for this species. Maintain pH between 7.8 and 9.0 using buffers or Tanganyikan salt mixes, with water hardness in the range of 10-20 dGH. Temperature should remain steady between 24-28°C. Ammonia and nitrite must always read zero, with nitrates kept below 20 ppm through regular water changes—aim for 25-30% weekly. Excellent oxygenation is crucial; Tanganyikan cichlids are intolerant of stagnant or oxygen-depleted conditions. Stability is paramount: avoid sudden parameter shifts that can trigger stress or disease. Use a reliable test kit to monitor calcium and magnesium levels, supplementing as necessary to maintain mineral-rich water chemistry.
Offer a varied diet centered on high-quality cichlid pellets or small floating foods formulated for carnivorous/omnivorous species, supplemented regularly with frozen and live foods such as mysis shrimp, brine shrimp, daphnia, and cyclops. This species naturally feeds on zooplankton and micro-invertebrates, so smaller meaty foods are ideal. Feed two to three times daily in moderate portions to mimic natural grazing behaviour. Avoid overfeeding with heavy sinking foods or excessive protein, which can lead to digestive issues and water quality problems. Include occasional vitamin-enriched preparations to support coloration and immune health. Observe feeding response carefully—the long snout is specialized for precision feeding, and this cichlid may be outcompeted by more aggressive tankmates at feeding time.
Ophthalmotilapia nasuta is a semi-aggressive species with fascinating social dynamics. Males establish and defend small territories, particularly during breeding periods, and engage in elaborate courtship displays involving body shimmering and fin spreading. Females and sub-dominant males form loose shoals in open water. Aggression is generally moderate compared to some Tanganyikan cichlids, but males can be territorial toward conspecifics and similar-looking species. This cichlid is active throughout the day, swimming gracefully in the mid to upper water column. In appropriately sized groups with proper sex ratios, much of the aggression is ritualized display rather than damaging combat. Provide sufficient space and visual barriers to allow subordinate individuals to escape dominant males' attention.
Compatible tank mates include other Lake Tanganyika cichlids of similar size and temperament, such as Cyprichromis species, Paracyprichromis, and peaceful rock-dwelling species like Julidochromis or Neolamprologus brichardi. Synodontis catfish from Lake Tanganyika make excellent bottom-dwelling companions. Avoid housing with aggressive Mbuna from Lake Malawi, highly territorial large cichlids, or very small species that may be bullied. Soft-water community fish are completely incompatible due to conflicting water chemistry requirements. Fin-nipping species and overly timid fish should also be excluded. In a well-planned Tanganyikan community with adequate space and rockwork, multiple species can coexist successfully, creating a dynamic and visually stunning display.
Males are polygamous and typically display in a lek-like setup where several males perform courtship rituals in close proximity, competing for female attention. Females are maternal mouthbrooders, incubating eggs and fry in their buccal cavity for approximately three weeks. To encourage breeding, provide a spacious aquarium with excellent water quality and maintain multiple females per male to distribute male attention. After spawning, the female retreats to a quiet area to brood. She will not eat during this period, and her throat pouch will visibly swell. Fry can be released naturally or the female can be carefully stripped in experienced hands. Newly released fry are relatively large and can accept newly hatched brine shrimp and finely crushed flake immediately. Provide hiding spaces for fry if raising them in the main tank, though a separate grow-out tank offers better survival rates.
