A remarkably peaceful, schooling African cichlid native to the deep, rocky habitats of Lake Tanganyika. They are famous for their unique behavior of swimming closely aligned to vertical rock faces or even hanging upside down in cave overhangs. They are maternal mouthbrooders that absolutely require groups, hard/alkaline water, and plenty of vertical rockwork.

Neon Blue Cichlid Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Male
Males sport striking neon blue horizontal stripes on a darker brown or purplish body. They establish temporary, three-dimensional territories against vertical rock structures to display and court females. Though they spar with other males, they rarely cause physical harm.
Differs in 2 traits from base species
Also known as: Male Blue Neon
Female / Unsexed Juvenile
Females are predominantly drab grey, beige, or light brown with very faint or absent striping. They are absolutely essential for a healthy school. Best kept in a ratio of 2 or more females per male to disperse constant courting attention.

Neon Blue Cichlid Care Guide Summary
The Neon Blue Cichlid, scientifically known as Paracyprichromis nigripinnis, belongs to the Cichlids - African family group. Adults reach a maximum size of approximately 11 cm and have a fusiform body shape with a moderate growth rate. Classified as mostly peaceful, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a low level of biological waste.
To thrive, the Neon Blue Cichlid requires a freshwater only aquarium with a minimum volume of 150 litres and a tank length of at least 90 cm. Water temperature should be maintained between 24°C and 27°C, with a pH range of 8–9 and a general hardness of 10–20 dGH. A moderate water flow is preferred.
The Neon Blue Cichlid is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Male and Female / Unsexed Juvenile. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Neon Blue Cichlid Habitat Setup
When setting up an aquarium for the Neon Blue Cichlid, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and smooth gravel or rounded substrate to protect their sensitive barbels.
Neon Blue Cichlid Compatibility Notes
Classified as mostly peaceful, the Neon Blue Cichlid is a schooling species that feels most secure in a sizeable group, where natural shoaling behaviour reduces stress and brings out their best colours. When choosing tankmates, their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Fish Similar to Neon Blue Cichlid
Cyprichromis Leptosoma
Cyprichromis leptosoma
A unique, pelagic (open-water) schooling cichlid endemic to Lake Tanganyika. Unlike rock-dwelling African cichlids, 'Cyps' live in massive shoals in the open water column where males display to females in spectacular 3D territories. They require very hard, alkaline water and a long tank (minimum 4 feet / 120cm) to accommodate their active swimming behavior.
Buffalo Head Cichlid
Steatocranus casuarius
A highly unique, riverine cichlid native to the fast-flowing rapids of the Congo River. It possesses a reduced swim bladder, meaning it 'hops' or 'jerks' along the bottom rather than swimming freely in the water column. Unlike Rift Lake African cichlids, it requires softer, neutral-to-acidic water and exceptionally high oxygenation/flow. They form strong monogamous pairs.
Lemon Cichlid (Leleupi)
Neolamprologus leleupi
A striking, torpedo-shaped cichlid endemic to the rocky shores of Lake Tanganyika. Famous for its intense yellow or orange coloration. They are highly territorial cave-dwellers that require hard, alkaline water. Due to their aggression toward their own kind, they are best kept as a solitary specimen or a confirmed breeding pair.
Blue Rainbowfish
Melanotaenia caerulea
A small, highly active, and colorful schooling fish native to the Kikori River system in Papua New Guinea. They are peaceful but require ample swimming space and a school of their own kind to thrive. Like most rainbowfish, they appreciate well-oxygenated, flowing water and are excellent jumpers. Males develop a striking blue hue with reddish horizontal stripes.
Azureus Cichlid
Copadichromis azureus
A stunning open-water 'Utaka' cichlid from Lake Malawi. Males develop a spectacular metallic blue coloration, making them popular centerpieces in African Cichlid tanks. Compared to rock-dwelling Mbuna, they are relatively peaceful open-water swimmers but still require ample swimming space and hard, alkaline water.
Cobalt Blue Zebra
Metriaclima callainos
A striking and highly active Mbuna cichlid endemic to the rocky shores of Lake Malawi. Known for its brilliant, solid cobalt blue coloration (though white morphs exist). Like most Mbuna, they are highly territorial, rock-grazing herbivores. They require an alkaline environment, a sandy substrate for digging, and extensive rockwork to establish territories. To manage aggression, they are best kept either in heavily populated, mixed all-male Mbuna tanks or in species harems (1 male to 3+ females).
