African Jewel Cichlid

Hemichromis bimaculatus

Cichlids - African

A strikingly beautiful but notoriously aggressive West African riverine cichlid. Unlike the alkaline-loving Rift Lake cichlids (e.g., Mbuna), Jewel Cichlids prefer neutral, softer water parameters. They are renowned for their brilliant red breeding dress and iridescent blue spots, but also for their extreme territoriality, especially when forming pairs and spawning. They are avid diggers and will uproot most plants.

Standard

The standard African Jewel Cichlid. Best kept as a solitary specimen in a community of similarly sized, robust fish, or as a single mated pair in a species-only tank. If a pair forms, they will violently defend their territory against all other tank mates.

African Jewel Cichlid Care Guide Summary

The African Jewel Cichlid, scientifically known as Hemichromis bimaculatus, belongs to the Cichlids - African family group. Adults reach a maximum size of approximately 14 cm and have a compressed body shape with a moderate growth rate. Classified as aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a high level of biological waste.

To thrive, the African Jewel Cichlid requires a freshwater only aquarium with a minimum volume of 110 litres and a tank length of at least 90 cm. Water temperature should be maintained between 22°C and 28°C, with a pH range of 6.57.5 and a general hardness of 415 dGH. A moderate water flow is preferred. An aquarium test kit can help you monitor these values.

Due to its specialist needs, the African Jewel Cichlid is best suited for fishkeepers who can provide a carefully planned setup. The African Jewel Cichlid is typically available in one standard form.

African Jewel Cichlid Habitat Setup

When setting up an aquarium for the African Jewel 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, smooth gravel or rounded substrate to protect their sensitive barbels, and driftwood, which can serve as both a hiding place and a dietary supplement. Keepers should note that expect substrate disturbance, so lightweight décor should be secured and live planted layouts may be difficult to maintain, as this species tends to uproot or consume vegetation. Browse aquarium sand substrate options to find the best fit.

African Jewel Cichlid Compatibility Notes

Classified as aggressive, the African Jewel Cichlid is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, conspecific aggression can be intense, especially in smaller tanks and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Auratus Cichlid (Mbuna)

Melanochromis auratus

Cichlids - African
11 cm Highly Aggressive

The Auratus Cichlid is a stunning but notoriously aggressive Mbuna from Lake Malawi. They exhibit extreme sexual dimorphism. They are strictly rock-dwellers that graze on algae (aufwuchs). Due to their hyper-aggressive nature, they must be kept in species-only or carefully managed, overstocked Mbuna setups with a strict harem ratio (1 male to several females) to disperse aggression.

Duboisi Cichlid (Tropheus)

Tropheus duboisi

Cichlids - African
12 cm Aggressive

An iconic Lake Tanganyika cichlid famous for its dramatic life-stage color change. Juveniles are jet black with brilliant white polka-dots, while adults develop a blue head and a distinctive yellow or white vertical band across a dark body. They are highly aggressive toward their own kind and must be kept in large colonies (10+) to disperse aggression. They are strict herbivores that require a specialized diet to avoid fatal digestive issues.

Red Devil Cichlid

Amphilophus labiatus

Cichlids - Central American
35 cm Highly Aggressive

A massive, extremely aggressive Central American cichlid. Aptly named, the Red Devil is highly intelligent, interactive, and famous for 'glass-banging' at their owners. They are powerful diggers that will uproot plants and rearrange decor. Because of their sheer aggression and jaw strength, they are almost exclusively kept as 'wet pets' in solitary setups.

Peacock Cichlid (Aulonocara)

Aulonocara sp.

Cichlids - African
15 cm Semi-Aggressive

Endemic to Lake Malawi, Peacock Cichlids are highly sought after for the breathtaking colors of the males. They are benthivorous, using sensory pores on their jaws to hunt small invertebrates in the sand. While territorial, they are generally peaceful compared to their aggressive Mbuna cousins. They require hard, alkaline water and a sandy substrate to prevent gill damage while sifting.

Cuckoo Catfish

Synodontis multipunctatus

Catfish
25 cm Semi-Aggressive

A striking African catfish famous for its 'cuckoo' breeding strategy, where it sneaks its eggs into the clutches of mouthbrooding cichlids. They are highly active, social, and thrive in hard, alkaline water typical of Lake Tanganyika. They must be kept in groups to diffuse conspecific aggression and are best kept with Rift Lake cichlids.

Kribensis

Pelvicachromis pulcher

Cichlids - African
10 cm Semi-Aggressive

A vibrant and highly popular dwarf cichlid native to the slow-moving rivers of West Africa. Unlike Rift Lake African cichlids, they prefer soft, slightly acidic water and densely planted tanks. They are generally peaceful in a community tank but become fiercely territorial and aggressive when breeding, often digging pits in the substrate and claiming the bottom zone. They are cave spawners and require hiding spots like driftwood or coconut shells.
