Food and Feeding

The Trewavas Mbuna (Labeotropheus trewavasae) is primarily herbivorous, thriving on a diet rich in plant matter. A high-quality spirulina-based flake or pellet should serve as the staple diet. Additionally, they will accept dried, frozen, or fresh vegetables such as spinach, lettuce, and zucchini. Avoid high-protein foods like bloodworms, as these can lead to digestive issues. Feeding should be done in small portions multiple times a day to prevent overconsumption and maintain water quality.

Sexing

Sexing Labeotropheus trewavasae is relatively straightforward. Males typically display a deep blue coloration with dark vertical bars, complemented by orange to red fin highlights. Females, on the other hand, exhibit more variable coloration, ranging from duller blue to brownish tones, often with a less pronounced pattern.

Breeding

This species is a maternal mouthbrooder, a characteristic common among mbuna cichlids. After spawning, the female collects the fertilized eggs in her mouth, where they are incubated for approximately 21 days. During this period, she may eat less or not at all. Once the fry hatch, she releases them into the tank, where they can be fed finely crushed flake food and baby brine shrimp. Providing rock structures for shelter will increase fry survival rates.

Lifespan

With proper care, Labeotropheus trewavasae can live up to 10 years. Maintaining stable water parameters, offering a balanced diet, and providing a spacious environment will promote longevity and overall health.

Origin and Natural Habitat

Native to Lake Malawi in Africa, the Trewavas Mbuna inhabits rocky shorelines where they graze on algae and biofilm. Their natural habitat consists of clear, hard water with moderate to strong water currents, which should be replicated in a home aquarium.

Tank Requirements and Behavior

These fish are highly territorial and aggressive, particularly towards their own kind and other mbuna species. It is best to keep them in a well-structured aquarium of at least 150 liters (40 gallons) with plenty of rocks and caves to break lines of sight and reduce aggression. A ratio of one male to at least four females helps minimize stress and territorial disputes.

Suitable Tankmates

Due to their territorial nature, Trewavas Mbunas should be housed with similarly aggressive cichlids that share their Lake Malawi origin. Suitable tankmates include:

• Yellow Lab Cichlid (Labidochromis caeruleus)
• Zebra Cichlid (Maylandia zebra)
• Demasoni Cichlid (Pseudotropheus demasoni)
• Auratus Cichlid (Melanochromis auratus)

Suitable Plants

Although mbuna cichlids are not heavily reliant on plants, hardy species can be included to provide cover and improve water quality. Some recommended plants include:

• Anubias (Anubias spp.)
• Java Fern (Microsorum pteropus)
• Vallisneria (Vallisneria spp.)

Short Description

The Trewavas Mbuna (Labeotropheus trewavasae) is a striking and aggressive cichlid from Lake Malawi, best suited for experienced aquarists familiar with mbuna care. Due to their territorial behavior, they require a carefully structured tank with plenty of hiding spots and a controlled male-to-female ratio. Their diet should primarily consist of plant matter to prevent digestive issues. With proper care, they make a vibrant and active addition to an African cichlid setup.
