| The type locality, a black water creek was located in primary forest under a thick canopy and where water depth was only a few cms, likely due to the flat terrain. The creek is divided into several smaller streams and covered a wide stretch of the forest floor. Rivulus flammaecauda was more abundant in deeper, open areas (Ref. 130065). |
