Threadfin Rainbowfish is an excellent choice for any planted aquarium. Because of the lengthy feather-like extensions displayed on the males of the species, this rainbow is easily distinguished from other rainbowfish.
 In the correct lighting, males will show green, red, and blue body colors, which can extend into their lengthy fins. Colors become even more brilliant as the fish gets larger.Â
This species breeds best in groups of six or more, but it can also be bred in groups of three in some situations.
Threadfin Rainbowfish prefer clean, slow-moving streams, grassy marshes, and lagoons with lush flora. Young fish and females will cluster in big groups in the shoreline plants and fallen branches.Â
Mature males will congregate in these groups, exhibiting their colors to the females in the hopes of attracting a mate. The appearance of these fish’s fins is determined by the environment in which they live.
