Author: (Pellegrin, 1903)
FBname: Curve-bar cichlid
Remark: See Miller 1956:15 for information on type locality.
Comments: This species inhabits a karstic warm spring, Media Luna, which exists because of a tectonic ridge forming a hill southwest (SW) of El Jabalí.  This spring formerly emptied into Rio Viejo, which has been blocked and diverted for agricultural purposes. It is sympatric with <i>H. bartoni</i> and <i>H. 
  cf carpintis</i> which was translocated into the Media Luna system (Ref. 94458).  Aquarium conditions:  pH=7, H=3, 25°C water temperature, omnivore, egg layer, needs plant and rock cover, not easy to raise in captivity.
