Red Cheek Tropheops - Pseudotropheus Tropheops

Red Cheek Tropheops | A Bold and Colourful Lake Malawi Mbuna

The Red Cheek Tropheops (Pseudotropheus tropheops) is a striking and characterful mbuna cichlid from the rocky shorelines of Lake Malawi in East Africa. Males display a vivid combination of deep blue-purple body colouration with distinctive reddish-orange cheek markings that give this species its common name — a bold contrast that makes them stand out immediately in a mixed mbuna setup. Females are typically yellow-orange, adding their own warm splash of colour to the tank and making sexing relatively straightforward compared to many other mbuna species.

Robust, active, and full of personality, the Red Cheek Tropheops is a rewarding species for aquarists with experience in African cichlid keeping who want something beyond the most commonly available mbuna varieties.

Red Cheek Tropheops Care Guide

Care at a Glance

• Scientific name: Pseudotropheus tropheops
• Also known as: Red Cheek Tropheops, Tropheops Red Cheek
• Origin: Lake Malawi, East Africa — rocky shoreline zones
• Adult size: up to 5 inches (13 cm) — males larger and more colourful than females
• Minimum tank size: 55 gallons — 75 gallons or more recommended for a community mbuna setup
• Temperature: 76–82°F (24–28°C)
• pH: 7.8–8.6 — hard, alkaline water essential
• Hardness: 10–20 dGH
• Best kept as one male with multiple females — aggression between males is significant
• Lifespan: 7–10 years with good care

Red Cheek Tropheops Tank Setup

A rocky aquarium replicating the natural shoreline habitat of Lake Malawi is essential. Stack rocks to create caves, crevices, and defined territories with open sandy areas between rock formations — reflecting the mix of rocky and sandy habitat this species occupies in the wild. Crushed coral or aragonite substrate naturally buffers water to the high pH and hardness Lake Malawi cichlids require and is strongly recommended.

Strong, efficient filtration and excellent water quality are non-negotiable — Lake Malawi is one of the clearest and most oxygen-rich bodies of water in the world, and mbuna kept in poor water quality deteriorate quickly. Regular bi-weekly water changes of 25–30% are essential.

Feeding Your Red Cheek Tropheops

Primarily herbivorous — in the wild, Tropheops species scrape algae and organic material from rocks using their specialised teeth. In the aquarium, offer high quality spirulina-based cichlid flake or pellet as the primary staple, supplemented with blanched vegetables such as spinach and zucchini. Frozen foods such as brine shrimp can be offered sparingly as an occasional treat. Avoid high-protein mammal-based foods such as beef heart, which can cause a potentially fatal digestive condition known as Malawi Bloat in herbivorous mbuna.

A Note on Aggression

Like all mbuna, Red Cheek Tropheops are assertive, territorial fish — particularly males toward other males of the same or similar species. Keep one male per species and provide sufficient rockwork to break sightlines and allow subordinate fish to escape visual contact. Overstocking is a widely used and effective strategy in mbuna keeping — a densely stocked tank with many individuals spreads aggression across multiple fish rather than allowing one dominant individual to fixate on a single target.

Red Cheek Tropheops Tank Mates

• Other mbuna cichlids of similar size and aggression level — Pseudotropheus, Labidochromis, Melanochromis, and Iodotropheus species
• Synodontis catfish — classic and natural Lake Malawi companions
• Avoid Aulonocara Peacock cichlids — typically too peaceful for a mbuna-dominated setup and will be bullied
• Avoid fish requiring soft, acidic water — water chemistry compatibility is essential
• Never keep two males of the same species together in anything but a very large, heavily structured aquarium
