Description
The Threadfin Rainbowfish is a small, elegant freshwater fish admired for the elaborate, thread-like extensions on its dorsal and anal fins, particularly in males. These peaceful schooling fish display iridescent colors and thrive in well-planted aquariums with gentle water flow. They are best kept in groups to showcase their natural behaviors and vibrant displays.
