The Threadfin Rainbow Fish is one of the most elegant and peaceful freshwater aquarium fish, admired for its slender body, iridescent colors, and long thread-like fins. When light hits its body, it displays shimmering shades of blue, yellow, and silver, making it a true showpiece in planted aquariums.

This species is highly active and social by nature, swimming gracefully in the mid-water level. Though sold as a single fish, Threadfin Rainbow Fish thrive best when kept in small groups, where their colors and fin extensions are displayed at their finest.
