The Red Top Black Bar Zebra Nakatenga (Metriaclima sp. 'Nakatenga') is a colourful mbuna cichlid from Lake Malawi in East Africa. It is highly regarded among African cichlid enthusiasts for its striking combination of a bright red or orange dorsal region and bold black vertical barring.

As a member of the mbuna group, it is an active, territorial rock-dwelling cichlid that thrives in aquariums designed to replicate the rocky shorelines of Lake Malawi.

Quick Facts

Appearance

Adult males are particularly impressive and typically display:

• Bright red to orange upper body and dorsal area
• Distinct black vertical bars
• Blue to bluish-grey body colouration
• Black edging on the fins
• Intense breeding colours when dominant

Females are generally less colourful and may display more subdued grey, blue or brown tones depending on lineage and social status.

Natural Habitat

This fish originates from rocky reef environments around Nakatenga Reef in Lake Malawi.

In the wild it inhabits:

• Rocky shorelines
• Boulder fields
• Areas with numerous crevices and caves
• Shallow to moderate depths

Like other mbuna, it spends much of its time grazing algae and associated microorganisms from rocks.

Aquarium Requirements

Tank Size

A minimum aquarium of 300 litres is recommended for a community of mbuna.

Larger aquariums are strongly preferred because they:

• Reduce aggression
• Allow more territories
• Improve water stability

Aquascaping

A suitable mbuna aquarium should include:

• Extensive rockwork
• Multiple caves and hiding places
• Stable rock structures
• Open swimming areas between territories

Many aquarists use limestone or similar calcareous rocks to help maintain alkaline water conditions.

Water Parameters

Maintain:

• Temperature: 24–28°C
• pH: 7.8–8.6
• GH: 8–20 dGH
• Ammonia: 0 ppm
• Nitrite: 0 ppm
• Low nitrate levels

Regular water changes and strong filtration are essential due to the heavy biological load typical of mbuna aquariums.

Temperament

The Red Top Black Bar Zebra Nakatenga is a typical mbuna:

• Territorial
• Energetic
• Competitive
• Sometimes aggressive

Males establish and defend territories among the rockwork and may relentlessly harass rivals in confined aquariums.

Aggression can often be managed through:

• Adequate tank size
• Heavy rockwork
• Proper stocking densities
• Suitable male-to-female ratios

Compatible Tank Mates

Suitable companions include other robust mbuna species such as:

• Labidochromis caeruleus
• Pseudotropheus acei
• Chindongo saulosi
• Other similarly tempered Metriaclima species

Avoid:

• Small community fish
• Peaceful South American cichlids
• Delicate species
• Fish requiring soft, acidic water

Feeding

This species is primarily herbivorous and should receive a diet rich in vegetable matter.

Suitable foods include:

• Spirulina flakes
• Spirulina pellets
• Algae-based foods
• Blanched spinach
• Blanched zucchini
• High-quality herbivore cichlid foods

Protein-rich foods should be fed sparingly.

Excessive animal protein may contribute to digestive disorders, including Malawi bloat.

Breeding

Like most mbuna cichlids, the Red Top Black Bar Zebra Nakatenga is a maternal mouthbrooder.

Breeding typically proceeds as follows:

1. The male establishes a spawning territory.
2. The female lays eggs.
3. The female collects the eggs in her mouth.
4. Fertilisation occurs during spawning.
5. The female incubates the eggs for approximately 18–28 days.
6. Free-swimming fry are released.

The fry can be fed:

• Newly hatched brine shrimp
• Finely crushed spirulina flakes
• Commercial fry foods

Common Health Issues

Malawi Bloat

A serious condition often associated with:

• Excessive protein in the diet
• Poor water quality
• Stress

Aggression-Related Injuries

Common signs include:

• Torn fins
• Missing scales
• Stress-related colour loss

Proper aquarium design greatly reduces these issues.

Colour Fading

Can result from:

• Poor nutrition
• Subordinate social status
• Stress
• Inadequate water quality
