Congo Tetra (Male)

The Congo tetra (Phenacogrammus interruptus) is a popular freshwater fish among aquarium enthusiasts. It is native to the Congo River Basin in Central Africa and is well-known for its vibrant, shimmering colors and peaceful temperament.

Key Characteristics:

• Size: Adults typically grow to about 810 cm (34 inches) in length.
• Coloration: They exhibit iridescent colors, often shimmering in shades of blue, green, orange, and violet. Males are more colorful and have longer, flowing fins compared to females.
• Body Shape: Congo tetras have an elongated body with a slightly compressed shape and distinctively large, fan-like dorsal and caudal fins.

Habitat and Behavior:

• Natural Habitat: They inhabit slow-moving streams and rivers in the Congo Basin, preferring soft, slightly acidic to neutral waters with plenty of vegetation.
• Behavior: They are schooling fish, meaning they thrive in groups of at least 68 individuals. Their behavior is peaceful, making them suitable for community aquariums.

Aquarium Care:

• Tank Size: A minimum of 30 gallons is recommended for a small school, with larger tanks being ideal.
• Water Parameters:
  • Temperature: 2327C (7381F)
  • pH: 6.07.5
  • Hardness: Soft to moderate
• Diet: They are omnivorous and will eat a varied diet of high-quality flake food, frozen or live foods (e.g., brine shrimp, daphnia), and vegetable-based foods.
• Tank Setup: Provide plants, open swimming space, and subdued lighting to mimic their natural habitat.

Breeding:

Congo tetras are egg scatterers, and breeding them requires a separate tank with fine-leaved plants or a spawning mop to collect eggs. They require specific water conditions and minimal disturbance for successful reproduction.
