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.


🐟 Demasoni Cichlid Overview

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)

📏 Size & Lifespan

Trait Details
Adult Size 2.5–3 inches (6–7.5 cm) — small for mbunas
Lifespan 5–10 years with proper care

🎨 Appearance

  • 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 & Behavior

  • 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.


🐠 Tank Requirements

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.


🍽️ Diet

  • 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.


✅ Care Tips

  • 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


🐣 Breeding

  • 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.


🤝 Tankmate Compatibility

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.


⚠️ Common Health Issues

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

🧠 Fun Facts

  • 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.


🏁 Summary

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.
