Threadfin Rainbowfish
Delicate, elegant, and incredibly eye-catching, the Threadfin Rainbowfish is one of the most unique Australian native fish available in the hobby. Known for their flowing, thread-like fins and peaceful schooling nature, these fish bring a touch of grace and movement to any planted or nano aquarium. Their shimmering bodies reflect hues of silver, gold, and subtle blue, especially when kept in well-lit environments.
As a true standout among rare rainbowfish, Threadfins are perfect for aquarists looking to keep something visually stunning yet gentle. Males develop elongated dorsal, anal, and caudal fins, making them a showpiece in any community setup.
Care Overview:
Threadfin Rainbowfish thrive in well-maintained, peaceful aquariums with soft lighting and fine-leaved plants. They are best kept in groups of 6 or more to encourage natural shoaling and display behaviour. These micro-predators enjoy small, frequent meals of baby brine shrimp, micro worms, crushed flakes, and other fine foods.
Ideal for nano tanks or aquascaped displays, they are a must-have for fans of Australian bred rainbowfish and small community fish setups.
Size: 3–5cm
