The Blue Dolphin Cichlid (Cyrtocara moorii) is a large, semi-aggressive African cichlid from Lake Malawi, prized for its powder-blue coloration and distinctive forehead hump. To thrive, it requires a spacious tank (minimum 100 gallons for a group), alkaline water (pH 7.8–8.6), and a carefully managed diet to avoid health issues like Malawi bloat.

🐟 Species Overview

  • Scientific Name: Cyrtocara moorii
  • Common Name: Blue Dolphin Cichlid
  • Origin: Lake Malawi, East Africa
  • Adult Size: 8–10 inches (20–25 cm)
  • Lifespan: 10–15 years
  • Temperament: Semi-aggressive, peaceful compared to Mbuna
  • Diet: Carnivorous sand-sifter (protein-rich foods)
  • Difficulty: Intermediate care level

🌊 Tank & Water Requirements

  • Minimum Tank Size: 100 gallons for a harem (1 male, 3+ females)
  • Water Parameters:
    • pH: 7.8–8.6
    • Hardness: 10–25 dGH
    • Temperature: 70–81°F (21–27°C)
  • Substrate: Aragonite sand (supports natural sifting behavior)
  • Filtration: Strong canister filters (high bio-load management)

🍽️ Diet & Feeding

  • Primary Foods: High-protein pellets, frozen foods (krill, mysis shrimp)
  • Supplement: Spirulina or fiber-rich foods to prevent Malawi bloat
  • Feeding Behavior: “Follower” strategy in the wild — sifts sand for small organisms

👫 Tankmates

  • Best Matches: Other peaceful Haps and Peacocks, Frontosa, Sailfin Pleco, certain catfish
  • Avoid: Aggressive Mbuna species (rock-dwellers)

⚠️ Risks & Challenges

  • Malawi Bloat: Caused by poor diet (too much protein, lack of fiber).
  • Aggression: Males can be territorial; maintain proper ratios.
  • Tank Size: Small tanks lead to stress and suppressed hump development.
  • Disease: Susceptible to Ich in high-alkalinity environments.
