Here's a complete care guide for the Demasoni Cichlid (Pseudotropheus demasoni) — a striking, vividly colored dwarf mbuna from Lake Malawi that captivates aquarists with its vibrant stripes and intense energy.
Trait | Details |
---|---|
Scientific Name | Pseudotropheus demasoni |
Common Names | Demasoni Cichlid, Dwarf Mbuna |
Origin | Lake Malawi, Africa — Pombo Rocks region |
Family | Cichlidae |
Group | Mbuna (rock-dwelling cichlids) |
Trait | Details |
---|---|
Adult Size | 2.5–3 inches (6–7.5 cm) — small for mbunas |
Lifespan | 5–10 years with proper care |
Color: Deep blue to purple body with bold black vertical stripes
Sexual Dimorphism: Males and females look very similar
Slightly more vibrant males
Males may develop slightly longer dorsal fins
Eyes: Dark with contrasting coloration for intense expression
Body: Compact, torpedo-shaped, muscular
🎯 Considered one of the most visually striking African cichlids despite its small size.
Temperament: Highly aggressive and territorial (especially toward similar-looking fish)
Behavior:
Very active and always on the move
Establishes and defends territory within rockwork
May harass less aggressive or similarly colored fish
Aggression increases during breeding or in tight spaces
⚠️ Aggressive but manageable with the right tank strategy.
Requirement | Recommended Setup |
---|---|
Tank Size | Minimum 30 gallons for a species-only tank, 55+ gallons for mixed mbuna tanks |
Temperature | 75–82°F (24–28°C) |
pH | 7.8–8.6 (alkaline) |
Hardness | 10–20 dGH |
Substrate | Sand or crushed coral |
Décor | Lots of rocks, caves, and hiding places |
Filtration | Strong biological + mechanical |
Lighting | Moderate — enhances color but doesn’t stress fish |
🧱 Rocks and crevices are essential to reduce aggression and mimic natural habitat.
Feeding Type: Herbivorous to omnivorous
Best Foods:
Spirulina flakes
Vegetable-based cichlid pellets
Blanched veggies (zucchini, spinach, peas)
Occasional protein: daphnia, brine shrimp
❌ Avoid meaty or high-fat foods like bloodworms — can cause Malawi Bloat.
Keep in groups of 10+ to spread aggression
Maintain 1 male to 4–5 females (if sex can be determined)
Rearrange rocks periodically to reset territorial lines
Perform weekly 30–40% water changes
Use buffering substrates (crushed coral, aragonite) to stabilize pH
Reproductive Strategy: Maternal mouthbrooder
Breeding Behavior:
Male courts female and leads to a flat rock
Female lays eggs and collects them in her mouth
Eggs incubate for 18–21 days
Fry are released and can be fed crushed flakes or baby brine shrimp
🐣 Demasoni breed readily in well-maintained setups, but separating fry may be needed to avoid predation.
Best Kept With:
Other Mbuna species (similar size and temperament)
Yellow Labs (Labidochromis caeruleus)
Rusty Cichlids (Iodotropheus sprengerae)
Acei Cichlids (Pseudotropheus acei)
Synodontis catfish
Avoid:
Peacocks and Haps (less aggressive and may be bullied)
Fish with similar color patterns (to reduce territorial attacks)
Delicate or slow-moving fish
Other Pseudotropheus demasoni males in small numbers (will fight)
🔁 Overstocking (with proper filtration) can diffuse aggression effectively.
Issue | Prevention/Treatment |
---|---|
Malawi Bloat | Avoid protein-heavy diet, keep stress low |
Fin Nipping | Provide plenty of hiding places |
Ich | Quarantine new fish, keep temp stable |
Color Fading | Improve diet, reduce stress and aggression |
Named after Ad Konings’ friend Laurence Demason, who helped in collecting specimens.
Despite being only 2.5–3", Demasoni cichlids often act as tank bosses in community setups.
Their color pattern resembles marine fish, making them popular with reef tank fans.
The Demasoni Cichlid is a compact powerhouse — brilliantly colored, highly active, and full of personality. Ideal for experienced cichlid keepers, they thrive in rocky Lake Malawi-style aquariums with high pH, clean water, and well-thought-out tankmate choices.
