Compressiceps Cichlid Care Guide - Habitat, Diet & Breeding

The Compressiceps Cichlid is a distinctive Lake Tanganyika predator with a laterally compressed body, a steep forehead and a large, powerful mouth. Its narrow profile allows it to slip into crevices while hunting, and its colouring varies from silver, grey and brown to darker barred or mottled forms depending on locality and mood.

Despite their unusual shape, these cichlids are active and purposeful swimmers. They often hover near rocks, inspect crevices and make sudden, accurate strikes at small fish or invertebrates. Adults can be territorial, particularly around a chosen cave or spawning site, although their behaviour is often more measured away from breeding areas.

In the wild, they inhabit the clear, highly alkaline waters of Lake Tanganyika. Rocky slopes, boulder fields and accumulations of empty snail shells provide shelter, hunting positions and breeding sites. Their elongated body and manoeuvrability are well suited to this complex environment.

Altolamprologus compressiceps is closely related to the similarly shaped Calvus Cichlid, but Compressiceps Cichlids generally develop a deeper, more robust head and body profile. Local colour forms can differ noticeably, making their geographic origin an important part of their appeal to Tanganyikan cichlid enthusiasts.

Compressiceps Cichlids are native to Lake Tanganyika in East Africa, where they occur along rocky shorelines and shell beds. Their range includes parts of Tanzania, Zambia, the Democratic Republic of the Congo and Burundi.

A single adult or carefully chosen pair should have at least 150 litres, with a larger aquarium of around 250 litres or more preferable for multiple fish or a community. Aim for a tank at least 120 cm long to provide meaningful territory and swimming space. Use a sandy substrate with piles of limestone rock, caves and empty escargot or similar shells, ensuring every structure is stable and cannot collapse. Open areas, strong filtration and good oxygenation suit their clear, mineral-rich lake habitat, while shell clusters provide essential refuge and spawning sites.

Males reach up to about 15 cm (6 in), while females are usually smaller at around 10–12 cm (4–4.7 in).

Compressiceps Cichlids are carnivorous predators. Offer a varied diet of high-quality carnivore pellets and granules supplemented with frozen or live foods such as mysis shrimp, krill, prawns and bloodworms. Feed modest portions, as their natural hunting style involves taking small prey rather than constantly grazing. Avoid relying on mammal-based foods, which are not appropriate for their digestive system.

Suitable companions include robust Lake Tanganyika species occupying different areas of the aquarium, such as Julidochromis, Neolamprologus leleupi, larger shell-dwelling Neolamprologus and peaceful Cyprichromis in a sufficiently spacious setup. Avoid small, timid fish that may be eaten, as well as boisterous African cichlids from incompatible water conditions. Keeping several unrelated adults together can lead to serious territorial conflict, so groups should be carefully planned and introduced into a well-structured aquarium.

Compressiceps Cichlids breed in narrow caves or suitably sized snail shells. The female enters the cavity and deposits a small number of eggs inside, while the male fertilises them from outside or by passing sperm into the opening. Provide several potential spawning sites and stable, mature water. The female guards the eggs and fry, which become free-swimming after roughly a week; newly hatched brine shrimp and other tiny foods are suitable for the young.

Males are typically larger and more heavily built, with a broader head and longer fin extensions as they mature. Females remain noticeably smaller and often have a more compact body, especially when compared with a fully grown male.
