Comments: Occurs in artificial wells with transparent water, depth range 6 to 12 m and diameter of approximately 1 m (Ref. 59347).  The water in the wells is used locally for human consumption.  This fish is often mistaken for parasitic leeches  " sanguijuelas" due to its bright, blood-red color  and vermiform shape. For this reason, this is killed upon incidental capture when extracting drinking water from wells.
