Demasoni

Demasoni (Chindongo demasoni, formerly Pseudotropheus demasoni) is a compact Lake Malawi mbuna known for alternating dark and bright blue bars. Adults generally reach around 8 cm, but their small bodies conceal a forceful temperament. This is a rewarding choice for a planned rock-dwelling cichlid aquarium with an owner ready to manage aggression.

Aquarium & care

Use a tank at least 120 cm long, approximately 55 US gallons or larger, with extra space for a substantial group. Provide sand and securely supported rockwork containing many escape routes and broken sightlines. Maintain hard, alkaline freshwater at 24–26°C and pH 7.5–8.5. Strong filtration, oxygenation and frequent partial water changes are essential. Increasing stocking density to disperse aggression requires additional filtration and monitoring; it is not a substitute for adequate space.

Feeding

Choose a high-quality mbuna food containing algae or spirulina and offer small portions. Supplement appropriately with vegetable foods. Avoid making rich meaty treats the main diet, and remove uneaten food before it degrades water quality.

Temperament & tankmates

Demasoni can seriously injure one another, particularly in a poorly planned pair or small group. Both sexes share similar coloration, so appearance alone does not provide reliable sex selection. Experienced keepers may maintain them with robust, compatible mbuna, avoiding similar blue-barred rivals and delicate peacocks. Watch for hiding, torn fins or missed meals and separate a bullied fish promptly.
