FBname: Hispaniolan rivulus
Remark: Incertae sedis:  presently not possible to assign to any genus until a complete set of morphological and molecular data can be analysed (Ref. 89845).
Comments: Inhabits headwater streams.  Associates with <i>Poecilia</i> and <i>Limia</i> species in small, sand-bottomed creeks with fast currents (Ref. 13498).  Not a seasonal killifish.  Is difficult to maintain in aquarium (Ref. 27139).
