Care Guide: Threadfin Rainbowfish are relatively undemanding but thrive in a well-maintained environment. Follow this care guide to ensure the optimal health and vibrant colors of your Threadfin Rainbowfish:

Tank Size:

  • Provide a tank of at least 20 gallons for a small group of Threadfin Rainbowfish. A longer tank with ample swimming space is preferable.

Water Parameters:

  • Temperature: Maintain a water temperature between 73-79°F (23-26°C).
  • pH: Keep the pH level in the range of 6.0-7.5.
  • Hardness: A moderate water hardness is suitable, ranging from 5-15 dGH.

Filtration:

  • Use a gentle filtration system to maintain water quality. Threadfin Rainbowfish prefer slow to moderate water flow.

Decor and Plants:

  • Include fine-leaved plants and floating vegetation to provide hiding spots and simulate their natural habitat.
  • Driftwood and rocks can be added, but leave open swimming spaces for their active behavior.

Diet:

  • Threadfin Rainbowfish are omnivores. Offer a balanced diet of high-quality flake or pellet food.
  • Supplement their diet with live or frozen foods such as brine shrimp, daphnia, and small insects.

Schooling Behavior:

  • Threadfin Rainbowfish are schooling fish that thrive in groups of six or more. Keeping them in a school reduces stress and encourages natural behaviors.

Compatibility:

  • Peaceful and compatible with other non-aggressive community fish of similar size.
  • Avoid housing them with fin-nipping or aggressive tankmates.

Water Changes:

  • Perform regular water changes of 20-30% weekly to maintain water quality.

Breeding:

  • Threadfin Rainbowfish are egg scatterers. Provide fine-leaved plants or a spawning mop for them to deposit their eggs.
  • Separate the adults from the eggs to prevent predation.

Note: The Threadfin Rainbowfish’s stunning appearance and peaceful demeanor make it an ideal choice for community aquariums. Their slender, thread-like fins and vibrant colors create a captivating display that enhances any aquatic setting.
