• Activity Level: They are active swimmers and enjoy exploring their environment, often displaying their vibrant colors when interacting with other fish or during territorial displays.
• Community Behavior: While they can coexist with other fish, careful selection of tankmates is essential to avoid aggression and stress.

Aquarium Care:

• Tank Size: A minimum tank size of 150 liters (40 gallons) is recommended for a small group of Blue Johanni Cichlids to provide adequate swimming space and territories.
• Water Parameters:
  • Temperature: They thrive in warmer water, with an ideal temperature range of 24°C to 26°C (75°F to 79°F).
  • pH: Slightly alkaline water is preferred, with a pH range of 7.5 to 8.5.
  • Hardness: They prefer hard water, with a general hardness (GH) of 10-20 dGH.
• Tank Setup:
  • Substrate and Decorations: A substrate of sand or fine gravel is recommended. Blue Johanni Cichlids enjoy a well-decorated tank with plenty of hiding spots created by rocks, caves, and decorations that mimic their natural environment.
  • Lighting: Moderate lighting is ideal for showcasing their vibrant colors without causing stress.
  • Filtration: A strong filtration system is essential to maintain water quality. Regular water changes (about 25% weekly) are important to keep the tank clean.

Diet:

• Blue Johanni Cichlids are omnivorous and require a varied diet to maintain their health and coloration. Their diet should include:
  • Pellets: High-quality cichlid pellets should form the staple of their diet.
  • Live or Frozen Foods: Offer live or frozen foods such as brine shrimp, Mysis, and daphnia to provide essential protein and variety.
  • Vegetable Matter: Incorporate some plant-based foods, such as spirulina flakes or blanched vegetables, to ensure a balanced diet.

Tankmates:

• Blue Johanni Cichlids can be housed with a variety of compatible species, provided they are not overly aggressive. Suitable tankmates include:
  • Less Aggressive Cichlids: Such as Lemon cichlid, Saulosi cichlid that thrive in similar water conditions.
  • Bottom Feeders: Such as Synodontis and Pleco's that can handle the presence of more dominant fish.
• Avoid housing them with aggressive species or fish that may provoke their territorial nature.
