A stunning but notoriously aggressive dwarf Mbuna from Lake Malawi. Known for its intense dark blue and black vertical stripes. They are strict herbivores (Aufwuchs grazers) and prone to 'Malawi Bloat' if fed high-protein diets. Due to extreme aggression toward their own kind, they require specific stocking densities.

Standard (Colony)
Demasoni are monomorphic (males and females look identical). To disperse their intense aggression, they must be kept in large groups of 12 or more. Keeping 2-11 individuals almost always results in the dominant male killing the others.

Demasoni Cichlid (Mbuna) Care Guide Summary
The Demasoni Cichlid (Mbuna), scientifically known as Chindongo demasoni, belongs to the Cichlids - African family group. Adults reach a maximum size of approximately 8 cm and have a fusiform body shape with a moderate growth rate. Classified as highly aggressive, this species primarily occupies the bottom and mid-level zones of the aquarium and produces a high level of biological waste.
To thrive, the Demasoni Cichlid (Mbuna) requires a freshwater only aquarium with a minimum volume of 200 litres and a tank length of at least 120 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 7.6–8.6 and a general hardness of 10–25 dGH. A high water flow is preferred. An aquarium test kit can help you monitor these values.
Due to its specialist needs, the Demasoni Cichlid (Mbuna) is best suited for fishkeepers who can provide a carefully planned setup. The Demasoni Cichlid (Mbuna) is typically available in one standard form.
Demasoni Cichlid (Mbuna) Habitat Setup
When setting up an aquarium for the Demasoni Cichlid (Mbuna), a high water flow best suits their natural preferences. Because this species occupies the bottom and mid-level 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 an established tank with natural algae growth, as they depend on it as a primary food source. 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.
Demasoni Cichlid (Mbuna) Compatibility Notes
Classified as highly aggressive, the Demasoni Cichlid (Mbuna) 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, conspecific aggression can be intense, especially in smaller tanks, territorial behaviour may cause issues if hiding spots or floor space are limited, and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the bottom and mid-level zones can help reduce competition and territorial overlap.

Similar Species
Auratus Cichlid (Mbuna)
Melanochromis auratus
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.
Yellow Lab (Mbuna)
Labidochromis caeruleus
The Electric Yellow Lab is one of the most popular and widely kept African Cichlids from Lake Malawi. Classified as an Mbuna (rock-dwelling cichlid), they are famous for their vibrant yellow coloration and striking black dorsal stripes. While considered one of the most 'peaceful' Mbuna, they are still highly territorial cichlids that require hard, alkaline water, a sandy substrate for digging, and abundant rockwork to establish territories.
African Jewel Cichlid
Hemichromis bimaculatus
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.
Duboisi Cichlid (Tropheus)
Tropheus duboisi
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.
Peacock Cichlid (Aulonocara)
Aulonocara sp.
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.
Frontosa
Cyphotilapia frontosa
A majestic and iconic deep-water cichlid from Lake Tanganyika, famous for its striking black and white bands and the prominent nuchal hump on its head. Despite their massive size, they are gentle giants compared to other African cichlids. However, they are highly effective piscivores and will easily consume smaller fish. They are best kept in a 'harem' colony of one male to multiple females.
