Size / Peso / Age
Maturity: Lm ?  range ? - ? cm
Max length : 5.0 cm TL maschio/sesso non determinato; (Ref. 27139)
Inhabits the banks of streams with little current, shallow and not so sunny, such as forest brooks. Occurs with other Rivulus (except R. geayi and R. ocellatus) as well as with some of Copella, Pyrrhulina, and Lithoxus (Ref. 35237). Not a seasonal killifish. Is very difficult to maintain in aquarium (Ref. 27139). Eggs measure 1.8 mm in diameter. Sexual differentiation is clearly set at two months although the recognition of the sexes is difficult before the age of 4 months when the first reproduction occurs. Proportion of males is far higher than females. Growth is slow (Ref. 35237).

Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref.
