Frequently found in shallow waters and is sympatric with other <i>Rivulus</i> of French Guiana except <i>R. ocellatus</i> (Ref. 27188).  Not a seasonal killifish.  Juveniles are released from eggs measuring 1.2 mm (Ref. 35237).  Sexual differentiation is possible at 4 months; sexual maturity is reached at 5 months of age (Ref. 27188).  Calm and passive; is easy to maintain in the aquarium (Ref. 27139).
