Protomelas taeniolatus Likoma

A Little More Information...

Protomelas taeniolatus Likoma, also known as Tangerine Tiger, is a highly sought-after geographic form of the Lake Malawi cichlid Protomelas taeniolatus. The Likoma Island population is noted for a particularly warm colour pattern, with orange and copper tones contrasting against the adult male’s blue hues. This large hap requires a spacious aquarium, alkaline water, and carefully selected tank mates. Its territorial behaviour is usually manageable when the layout provides enough shelter and broken lines of sight. Its availability is moderate, making this form less commonly encountered than several other Malawi cichlids.

General species description

Protomelas taeniolatus Likoma belongs to the large haplochromine cichlids of Lake Malawi. It is valued for its size, sturdy body shape, and strong contrast in mature breeding males. The Likoma form is a geographic population associated with Likoma Island, rather than a separate species. Like several Protomelas, it requires substantial bottom space and a structured layout. Mature males defend breeding territories, while females and juveniles display more subdued colours. A Malawi community aquarium can work well, but overly aggressive species and other fish likely to encourage hybridization should be avoided. This population is moderately uncommon in the aquarium trade.

Geographic origin and biotope

The species comes from Lake Malawi in East Africa. The form described here is associated with Likoma Island, located in the eastern part of the lake and administered by Malawi. Its natural environment includes clear rocky or sandy shores, with transition areas where rocks become less dominant. The water is hard, alkaline, and well oxygenated. Submerged vegetation is generally not the main feature of the shoreline, although it may occur in some calm, shallow areas. In an aquarium, strong circulation, efficient filtration, and a stable substrate reproduce these conditions more effectively than a densely planted layout.

Precise location and local name

The reference locality is Likoma Island in Lake Malawi. The island lies near the Mozambican shore, but it is part of Malawi. In the aquarium trade, this population is mainly identified by the locality name Likoma and the English vernacular name Tangerine Tiger. The latter refers to the orange to mandarin shades seen in adult males. It is a trade name used to distinguish this geographic form from other Protomelas taeniolatus populations, including fish sold as Namalenje or Ndiwe. The locality should be retained in breeding records to help prevent mixing between populations.

Appearance and physical characteristics

Protomelas taeniolatus Likoma has a deep, elongated, muscular body, a relatively broad head, and a terminal mouth suited to grazing and taking small prey. Mature males usually develop a blue or blue-green base colour, enhanced by orange-copper tones on the flanks and fins. The dorsal fin may show a dark edge or metallic highlights, depending on age, social rank, and lighting. Females remain more subdued, often grey-brown or silvery, with only lightly contrasting vertical markings. Size and colouration vary with rearing conditions. Sexual dimorphism becomes especially clear in mature males during the breeding period.

General diet

In nature, Protomelas taeniolatus Likoma mainly feeds on plant and animal matter collected from substrate surfaces, including biofilm, algae, and small invertebrates. In the aquarium, its diet should remain varied, with quality Malawi cichlid pellets as the staple and foods containing a meaningful vegetable component as regular supplements. Spirulina-based preparations can be offered routinely, while frozen foods such as brine shrimp or mysis should remain occasional additions. Avoid foods excessively rich in mammal meat and avoid overfeeding. Small portions offered once or twice daily help maintain good condition and reduce aquarium waste.

In your aquarium

To successfully keep Protomelas taeniolatus Likoma, provide an aquarium of at least 400 litres, powerful filtration, and a rock layout that creates shelters without restricting swimming space. Maintain hard, alkaline water with excellent stability and oxygenation. A ratio of one male to several females helps reduce territorial pressure. Select similarly sized tank mates without overly similar colours or body shapes, and watch for persistent harassment. A vegetable-oriented diet, regular water changes, and avoiding the mixing of geographic populations are essential for maintaining the health and quality of this form. Its moderate availability also makes careful breeder selection worthwhile.
