  1. Water Parameters:

Congo Tetras originate from the Congo River Basin in Africa, and they have specific water parameter requirements to thrive in captivity. Here are the ideal water parameters for Congo Tetras:

  • Temperature: 72°F to 82°F (22°C to 28°C)
  • pH Level: 6.0 to 7.5
  • Water Hardness (GH): 5 to 15 dGH
  • Ammonia and Nitrite Levels: 0 ppm (as these are toxic to fish)
  • Nitrate Levels: Below 20 ppm
  1. Tank Size and Setup:

Congo Tetras are active swimmers and should be kept in a spacious aquarium. A minimum tank size of 20 to 30 gallons is recommended for a small school of Congo Tetras. Providing plenty of swimming space and some hiding spots with live plants, rocks, and driftwood will help replicate their natural habitat.

  1. Best Tank Mates:

Congo Tetras are generally peaceful fish and can be kept with a variety of compatible species. However, it's essential to choose tank mates that won't harass or outcompete them. Suitable tank mates for Congo Tetras include:

  • Other Peaceful Community Fish: Rasboras, other Tetras (e.g., Neon Tetras), Corydoras catfish, and smaller peaceful Gouramis can be good companions.
  • Peaceful Bottom Dwellers: Kuhli Loaches and Otocinclus catfish are good choices as they occupy the lower regions of the aquarium.
  • Peaceful Dwarf Cichlids: Small and peaceful cichlids like Apistogramma species can coexist with Congo Tetras.
  • Avoid Aggressive Fish: Avoid aggressive or territorial fish, as they may stress or harm the Congo Tetras.

Remember, when introducing new fish to the tank, it's essential to monitor their behavior to ensure there is no aggression or compatibility issues.

Keep in mind that individual fish have unique personalities, and while Congo Tetras are generally peaceful, there may be exceptions. Providing ample space, hiding spots, and a well-maintained environment will help reduce stress and promote harmony among the tank inhabitants.

Overall, the Congo Tetra is a beautiful and captivating fish species, and with the right care and tank setup, they can thrive and become a stunning centerpiece in your aquarium.
