Pseudotropheus Greberi (Pseudotropheus greberi) — 4-5cm

Overview

The malawi cichlid Pseudotropheus greberi is a striking Lake Malawi mbuna cichlid with bold color, lively personality, and classic rock-dwelling behavior. Available for sale UK through Tropical Fish Co, this small, aggressive mbuna thrives in hard, alkaline water and brings vibrant color, energy, and activity to well-maintained Malawi biotope tanks.

Appearance

Pseudotropheus greberi reaches just 4–5 cm in length and displays a compact, laterally compressed body with vibrant coloration that varies depending on mood and maturity. Males typically show bright blue, yellow, or multicolored patterns, while females are often paler. The fins are short and rounded, and the overall appearance is bold and eye-catching.

Natural Habitat

This species is native to Lake Malawi, East Africa, where it inhabits rocky shorelines and intermediate zones with rubble, boulders, and crevices. In the wild, P. greberi feeds on aufwuchs (biofilm and algae) scraped from rocks, along with small invertebrates and organic matter. These environments are characterized by hard, alkaline water, high oxygen saturation, and intense competition for territory and resources.

Aquarium Setup

Provide a well-filtered aquarium of at least 100 litres with plenty of rockwork to create territories, caves, and hiding places. Use a sand or fine gravel substrate and arrange rocks to form vertical structures with multiple sight breaks. Strong filtration and excellent water quality are essential. Avoid overcrowding, and stock carefully to minimize aggression. Bright lighting suits this species well.

Water Parameters

Maintain hard, alkaline water between 24–26°C with a pH of 7.5–8.5. Regular partial water changes (30–50% weekly) and excellent filtration are essential to keep water pristine and stable. This species is sensitive to poor water quality and parameter fluctuations, requiring consistent maintenance. Use cichlid salts or buffer to maintain appropriate hardness and pH if necessary.

Feeding

Pseudotropheus greberi is an omnivore/algivore. Offer a primarily algae/aufwuchs-based mbuna diet with spirulina, algae wafers, and vegetable matter, plus small amounts of protein foods in moderation (brine shrimp, mysis). Avoid high-protein diets, as these can lead to digestive issues in mbuna. Feed once or twice daily, and remove uneaten food promptly.

Behaviour

This mbuna is aggressive, territorial, and highly active, especially males defending territories. Males establish territories among rocks and may display intense aggression toward conspecifics, similar-looking species, and other mbuna. Females are generally less aggressive but may become defensive when brooding. P. greberi is a maternal mouthbrooder, with females carrying eggs and fry in their mouths after spawning.

Tank Mates

Ideal companions include other robust Lake Malawi mbuna, similar-sized African cichlids with comparable temperament, and Synodontis catfish. Avoid peaceful community fish, small fish, shrimp and other small invertebrates, slow-moving or long-finned fish, and overly aggressive species that may provoke constant fighting. Choose tankmates that appreciate similar hard, alkaline conditions.

Breeding

Maternal mouthbrooder; males establish territories and court females. Provide rockwork and multiple hiding places, and remove fry or use a separate breeding setup if needed. Females carry eggs and fry in their mouths for 3–4 weeks. Fry are released when free-swimming and can be fed baby brine shrimp and finely crushed foods.
