Running River Rainbow (No Online Purchases)

The term "Running River Rainbow" likely refers to a specific population or color variant of the Eastern Rainbowfish (Melanotaenia splendida splendida). Eastern Rainbowfish are widespread throughout eastern Australia, and various populations exhibit regional differences in coloration and finnage.

• Appearance:
  • Body Shape: Elongated and laterally compressed, typical of rainbowfish.
  • Coloration: The base color is usually silvery to bluish-green. Males are typically much more colorful than females, especially during breeding displays. The specific colors of the Running River population might be particularly vibrant or have unique patterns. Expect to see combinations of:
    • Reds: Along the fins and sometimes the body.
    • Yellows: Often present on the fins and flanks.
    • Blues and Greens: Forming iridescent stripes or highlights.
    • Dark stripes: Running horizontally along the body.
  • Fin Shape: Males often have more extended and colorful fins. The dorsal fin is typically in two parts.
• Size: Eastern Rainbowfish generally grow to around 8-12 cm (3-5 inches), with males often being larger. 
• Habitat (in the wild): The Running River is located in Queensland, so these rainbowfish would be adapted to the freshwater conditions of that specific river system, likely including clear, flowing water with vegetation.
• Temperament: Eastern Rainbowfish are generally peaceful and active schooling fish.

Aquarium Care :

• Tank Size: A tank of at least 75 liters (20 gallons) is recommended for a small school, with larger tanks being better to accommodate their active swimming. A longer tank is preferable.
• Water Parameters:
  • Temperature: 22-28°C (72-82°F).
  • pH: 6.5-7.5.
  • Hardness: Soft to moderately hard (50-150 ppm or 3-15 dGH).
• Substrate: A dark substrate can help to enhance their colors.
• Plants and Decorations: They appreciate a well-planted tank with open swimming areas. Live plants are beneficial.
• Lighting: Moderate lighting is suitable.
• Filtration: Good filtration is essential to maintain water quality.
• Social Behavior: Keep them in schools of at least six or more to observe their natural behaviors and reduce shyness.
• Tank Mates: They are compatible with other peaceful community fish of similar size and temperament.
• Diet: They are omnivores and will accept a varied diet of high-quality flake food, pellets, and small live or frozen foods.
