Freshwater Rainbowfish • Nano Community Species • Display Fish • Delicate Finned Swimmer
 
📋 The Threadfin Rainbowfish (Iriatherina werneri) is a delicate and elegant nano rainbowfish prized for its long flowing fins, shimmering body, and graceful movement. Males develop dramatic filament-like extensions on their dorsal, anal, and caudal fins, performing elaborate displays to attract females.
This species thrives in peaceful, planted aquariums with gentle water flow. Because of its tiny mouth and delicate fins, the Threadfin Rainbowfish requires micro-sized foods and should not be mixed with boisterous tank mates. When kept in groups, males exhibit impressive displays, making them one of the most captivating nano fish available.
