Altolamprologus compressiceps

A Little More Information...

Altolamprologus compressiceps, also called Chaitika Orange Calvus, is an elegant cichlid from Lake Tanganyika in East Africa. Its strongly laterally compressed body allows it to slip between rock crevices, where it hunts small prey and finds shelter. The Chaitika form is recognized by its copper-orange coloration, especially visible on the head, fins, and caudal peduncle. Despite its moderate size, this fish has a distinct temperament, particularly during spawning. It is suited to a rocky aquarium with hard, alkaline, stable water and clearly separated territories.

General species description

Altolamprologus compressiceps is a shell-dwelling and rock-associated cichlid in the genus Altolamprologus. Its tall, strongly compressed body gives it a distinctive shape, perfectly suited to life among the rocky screes of Lake Tanganyika. It often remains motionless beside a crevice before making a rapid dash to capture prey. Its behavior is generally calm toward fish using different areas, but it becomes territorial around its shelter or spawning site. Chaitika Orange Calvus is a commonly used aquarium and trade name in the specialized hobby. It remains a popular choice for a Tanganyikan biotope aquarium, provided the water is hard, alkaline, and very stable.

Geographic origin and biotope

The species comes from Lake Tanganyika, especially rocky shoreline areas in Tanzania and nearby regions of the lake basin. It inhabits mineral-rich shorelines, stone piles, and crevices that serve as both shelter and territory. The water is clear, highly mineralized, and alkaline, with a relatively stable tropical temperature. Aquatic vegetation is generally sparse in exposed rocky areas; the habitat is dominated by boulders, slabs, and narrow openings. In an aquarium, this environment should be recreated with firmly placed rocks that have no sharp edges, while excellent water quality is maintained. Moderate to strong circulation and efficient filtration are well suited to this habitat, which contains little decomposing organic material.

Precise locality and local name

The name Chaitika refers to a locality along Lake Tanganyika used in the aquarium trade to identify this geographic form. Chaitika Orange Calvus is primarily a vernacular or commercial name rather than a documented traditional name in a local language. This locality reference matters because populations of Altolamprologus compressiceps may show differences in coloration according to their area of origin. To preserve their geographic identity, it is best not to mix this form with other populations when breeding. In stores, the name may also be shortened to Orange Calvus.

Appearance and physical characteristics

The body of Altolamprologus compressiceps is notably tall, laterally compressed, and covered with large scales. Its heavy head, sloping forehead, and protrusible mouth create a distinctive profile. The Chaitika Orange Calvus form displays orange to copper highlights, sometimes with brownish or golden tones, while the body often retains a dark, metallic coloration. The dorsal and anal fins are elongated, and their spiny rays provide protection against predators. The eyes are relatively large and suited to hunting in rocky areas with limited light. Adult males generally grow larger than females, which remain smaller and often more compact.

General diet

In the wild, Altolamprologus compressiceps is an opportunistic predator that captures small fish, fry, and various aquatic invertebrates. Its protrusible mouth allows it to seize prey quickly from a crevice or as it passes nearby. In an aquarium, its diet should remain protein-rich but not excessive. High-quality sinking pellets for carnivorous cichlids can form the staple, supplemented with frozen foods such as mysis shrimp, brine shrimp, and small crustaceans. It is better to offer small regular portions rather than one large meal. Live foods can encourage hunting behavior and breeding condition, but they should come from a safe source. A varied diet helps maintain coloration and growth without unnecessarily polluting the water.

In your aquarium

Success with Altolamprologus compressiceps depends on hard, alkaline water, powerful filtration, and a stable rocky layout with several shelters. Each fish should be able to retreat from the others visually, especially during spawning. Avoid tankmates that are overly aggressive or small enough to be swallowed. A varied carnivorous diet, small portions, and regular water changes support good condition. Since the Chaitika Orange Calvus form is commonly available through the specialized aquarium trade, select well-identified, acclimated fish whenever possible, and preserve their locality information when breeding.
