Comments: <i>E. chevalieri chevalieri</i> occurs in small rivers, creeks and swamps in the rainforest and forested savannah, while <i>E. chevalieri nigricans</i> is most probably restricted to forested areas and is not expected to inhabit the adjacent savannah (Ref. 47774).  Not a seasonal killifish.  Is very difficult to maintain in aquarium (Ref. 27139).
