Comments: Occurs in limestone caves.  Found concentrated in places with the bottom formed by clay and small blocks of limestone, usually hiding under these blocks and inside crevices in the walls, thereby allowing a strong cryptobiotic habit. When not hidden, this species prefers to stay on the bottom and on walls (rcky and silt substrate) with occasional incursions into the midwater and surface.  Inhabits water bodies formed by infiltration in the rock, and, because of this, it must be considered fragile and as a priority in conservation programs of Brazilian karstic areas (Ref. 91769).
