Comments: Occurs in pools in a set of rimstone dams (wall-shaped barriers of calcite, aragonite or other chemical deposits that impound water pools), 10-30 cm deep and with rocky bottom (Ref. 55401).  A solitary species, swimming on the bottom, along the walls and sometimes at the surface of the pools (Ref. 55401).
