Brevis Mbuna (Melanochromis brevis) — 7-9cm

Overview

The Brevis Mbuna (Melanochromis brevis) is a captivating African cichlid endemic to the rocky shores of Lake Malawi. Known for its striking coloration and dynamic personality, this mbuna species thrives in hard, alkaline water and brings authentic Rift Lake energy to your aquarium. Available for sale UK-wide, the Brevis Mbuna is a rewarding choice for aquarists seeking an active, colorful centerpiece fish with moderate care requirements.

Appearance and Coloration

Melanochromis brevis displays bold, contrasting colors that vary by sex and mood. Males typically exhibit vibrant blue or electric blue flanks with dark vertical bars, while females and juveniles show more subdued tones of brown or olive with lighter barring. During courtship and territorial displays, males intensify their coloration, creating a mesmerizing visual spectacle. The Brevis Mbuna's compact, torpedo-shaped body and alert expression make it a classic representation of Lake Malawi's mbuna group.

Natural Habitat

Endemic to Lake Malawi in East Africa, Melanochromis brevis inhabits rocky areas around Nkudzi Bay and Monkey Bay. These fish live among crevices and boulder fields, grazing on algae and biofilm while defending territories against conspecifics and other mbuna. The lake's hard, alkaline water (pH 7.5-8.6) and stable tropical temperatures create an environment that must be replicated in captivity for optimal health and behavior.

Aquarium Setup

A minimum 150-litre aquarium is essential for the Brevis Mbuna, with larger tanks preferred for community setups. Construct a rocky aquascape using slate, lava rock, or limestone to create multiple territories and hiding spots. Arrange caves and crevices at various heights to minimize aggression and provide refuge for subdominant fish. A sandy substrate mimics the lake floor, and robust plants such as Anubias or Vallisneria can be anchored among rocks, though many mbuna nibble vegetation.

Water Parameters

Maintain hard, alkaline water with pH 7.5-8.6 and temperatures between 24-28°C. General hardness (GH) should be 10-20 dGH, and carbonate hardness (KH) 8-15 dKH. Use a high-quality external filter to ensure excellent water circulation and oxygen levels, as mbuna are active fish with high metabolic rates. Perform 25-30% weekly water changes to control nitrate buildup and maintain stable parameters. Avoid acidic or soft water, which stresses Rift Lake cichlids.

Feeding and Diet

Melanochromis brevis is primarily herbivorous but accepts some animal protein. Offer spirulina-based flakes or pellets as the staple diet, supplemented with blanched vegetables such as zucchini, spinach, or peas. Occasional small meaty foods like brine shrimp or bloodworms can be provided, but avoid high-protein diets that may cause bloat. Feed small portions 2-3 times daily, ensuring all food is consumed within a few minutes to prevent water quality degradation.

Behaviour and Personality

The Brevis Mbuna is a lively, semi-aggressive fish that establishes and defends territories within the aquarium. Males are particularly territorial, especially during breeding, and may spar with other males or similarly colored species. This species exhibits natural grazing behavior, constantly picking at rocks and décor for algae. While not peaceful, Melanochromis brevis can coexist with other robust mbuna of similar size and temperament in a well-structured tank with ample hiding places.

Tank Mates

Ideal tank mates include other Lake Malawi mbuna of similar size and temperament, such as Pseudotropheus, Labidochromis, and other Melanochromis species. Robust Lake Malawi cichlids like Aulonocara or larger Haplochromis can also work in spacious tanks. Synodontis catfish are excellent bottom dwellers that tolerate the alkaline conditions. Avoid small, peaceful fish, long-finned species, slow-moving fish, overly aggressive large cichlids, and soft-water community species, as these will be harassed or outcompeted.

Breeding

Melanochromis brevis is a maternal mouthbrooder. Males establish territories and display vibrant colors to attract females. After courtship and spawning, the female collects and incubates eggs in her mouth for approximately three weeks. During this period, she does not eat and should be monitored closely. Provide rockwork with multiple caves and shelters to reduce stress on brooding females. Once released, fry are free-swimming and can be fed crushed flake, baby brine shrimp, or specialized fry foods. Separate fry if adult predation is a concern.
