Callochromis macrops 4 - (Callochromis macrops) — 4-5cm

Overview

The Callochromis macrops is a striking Lake Tanganyika sand-dwelling cichlid with elegant behavior and specialized care needs, best suited to experienced aquarists. Endemic to the sandy bottoms of Lake Tanganyika, this species (adult size around 13.5 cm) thrives in hard, alkaline water and rewards dedicated keepers with fascinating mouthbrooding displays and graceful, sand-sifting behaviour. With its slender body and subtle beauty, C. macrops is a prized choice for advanced Tanganyikan biotope aquariums.

Appearance

Callochromis macrops displays a slender, streamlined body with subtle coloration ranging from pale silver-grey to golden-beige, often with iridescent highlights on the scales and gill covers. Males develop more intense colours, especially during breeding, with hints of blue or violet on the head and fins. The body is laterally compressed and elegantly proportioned, with large eyes adapted for detecting prey in sandy substrates. The overall appearance is both graceful and functional, typical of Tanganyikan sand-dwellers.

Natural Habitat

This species is endemic to Lake Tanganyika, where it inhabits sandy bottoms near rocky areas at moderate depths. The lake's ancient, stable chemistry—characterised by high mineral content, exceptional clarity, and warm temperatures—has shaped the evolution of hundreds of endemic cichlid species. In nature, Callochromis macrops forage on sandy substrates, using specialized sensory pits to detect small invertebrates and crustaceans buried in the sand.

Aquarium Setup

Recreate a Tanganyikan sand-dwelling biotope with a fine sandy substrate (5–10 cm deep), open bottom space, and some rock cover to provide visual barriers and shelters. Use minimal decor to allow ample swimming and foraging area. Ensure stable water chemistry: pH 8.0–9.0, hard water (GH 12–20°), and a temperature of 24–28°C. A minimum of 300 litres is essential to accommodate the species' size and sand-sifting behaviour. Provide strong filtration, regular water changes, and moderate lighting to bring out natural colours.

Water Parameters

Like all Tanganyikan cichlids, Callochromis macrops demands pristine, stable conditions. Aim for 24–28°C, pH 8.0–9.0, and high hardness. Conduct weekly partial water changes (20–30%) to maintain low nitrate levels and replenish essential minerals. Use a high-quality filter rated well above the tank volume, and consider adding crushed coral or Tanganyikan salts to buffer water chemistry. Stability is critical—avoid sudden fluctuations in temperature or pH.

Feeding

In the wild, Callochromis macrops feeds primarily on small invertebrates, crustaceans, and insect larvae buried in sandy substrates. In captivity, offer a varied carnivorous diet: quality cichlid pellets, frozen or live foods such as brine shrimp, mysis, daphnia, and small crustaceans, with occasional protein-rich supplements. Feed small portions once or twice daily. A balanced, protein-rich diet supports vibrant coloration, healthy growth, and successful breeding.

Behaviour

This species is semi-aggressive, with males becoming territorial especially when defending spawning territories or courting females. Outside breeding periods, Callochromis macrops are relatively peaceful and spend much of their time sifting through sand in search of food. Watching their graceful foraging behaviour is one of the highlights of keeping this species. Provide ample space and visual barriers to reduce aggression.

Tank Mates

Suitable companions include other Tanganyikan cichlids of similar size and temperament, such as sand-dwelling species from Lake Tanganyika, or robust, non-aggressive Tanganyikan species in a suitably large tank. Avoid small fish that may be bullied or eaten, highly aggressive cichlids, fin-nipping species, soft-water community fish, or overly boisterous tankmates. Careful planning and adequate space ensure a harmonious Tanganyikan sand-dwelling community.

Breeding

Callochromis macrops is a maternal mouthbrooder. Best bred in a species tank or carefully planned Tanganyika setup with a ratio of one male to several females. Provide fine sand and open bottom space; females incubate eggs and fry in the mouth for about 3–4 weeks. Fry can be fed newly hatched brine shrimp or specialist fry foods once released. Maintain excellent water quality and stable Tanganyikan conditions to support successful breeding.
