Keeping Australian Rainbowfish in an aquarium requires the right conditions.

Aquarium Information

  • Care level: intermediate
  • Temperament: peaceful
  • Diet: omnivore
  • Minimum tank size: 30 gallons (for smaller species, larger for others)
  • Compatibility: Excellent with other peaceful community fish of similar size, such as tetras, rasboras, corydoras, and other rainbowfish species. Avoid housing with aggressive or fin-nipping species.
  • Special requirements: Rainbowfish thrive in well-planted aquariums with open swimming spaces. They prefer subdued lighting and benefit from a varied diet including high-quality flakes, pellets, and live or frozen foods. Maintaining a school of at least 6-8 individuals is crucial for their well-being and to observe their natural schooling behavior and vibrant colors.
