Hardness: 10 – 20 dGH

🐟 Characteristics

Body: Stout, oval-shaped cichlid with a slightly protruding mouth adapted for algae scraping.
Coloration:
• Juveniles — black or dark blue body covered in bright white spots.
• Adults — lose their spots and develop a solid dark blue-black body with a vivid yellow or golden band around the midsection (Maswa or Yellow Band variant).
Behavior: Territorial and hierarchical, especially among males; best kept in groups to distribute aggression.
Unique Feature: Distinct color transformation from spotted juvenile to banded adult — one of the most striking in African cichlids.
Nature: Active, social herbivore requiring constant grazing opportunities.

🍽️ Food

Type: Primarily herbivorous (aufwuchs grazer)
Diet: Spirulina flakes, algae wafers, blanched spinach, and vegetable-based pellets. Occasionally offer frozen mysis or brine shrimp.
Feeding Frequency: 2–3 times daily in small amounts.
Tip: Avoid protein-rich foods (like bloodworms) — can cause bloating.

🛠️ Maintenance

Tank Size: Minimum 75 gallons (280 L) for a group of 10 or more.
Filtration: Strong filtration with high oxygenation and steady water movement.
Decor: Rocky aquascape with caves, crevices, and flat stones; open sand areas for swimming.
Lighting: Moderate to bright; supports natural algae growth.
Water Change: 25–30% weekly to maintain pristine, alkaline conditions.

👥 Social Behavior

Group Size: Keep in groups of at least 10–12 individuals to manage aggression.
Tank Mates: Other Tanganyikan cichlids with similar temperament — such as Tropheus moorii, Julidochromis, or Eretmodus species.
Avoid: Small, timid, or soft-water species; also avoid mixing with aggressive Mbuna from Lake Malawi.

✅ Do’s

• Keep in large groups to reduce territorial fighting.
• Maintain hard, alkaline water typical of Lake Tanganyika.
• Feed mostly vegetable-based foods.
• Provide plenty of rockwork and hiding areas.

❌ Don’ts

• Don’t feed high-protein or meaty diets.
• Don’t mix with soft-water or small tropical fish.
• Don’t keep in pairs or trios — leads to extreme aggression.

⭐ Quick Tips

The Yellow Band Duboisi (Tropheus duboisi) is a stunning African cichlid famous for its color transformation and social colony behavior. Its yellow mid-body band and deep blue-black coloration make it a standout showpiece in Tanganyikan biotope aquariums. Best for experienced aquarists who can maintain large, stable, alkaline setups with a strong focus on group dynamics and herbivorous feeding.
