Lives in schools of about several dozen individuals, in muddy creeks or along the sandy-muddy edge of shallow estuarine zones. Sometimes stays motionless at the surface and prefers to seek shelter beneath floating plants. Fertilization is internal (Ref. 35237). Several days after fertilization, females lay eggs individually on aquatic plants. 7 cm male 8 cm female max TL (Ref. 026130, needs confirmation). Not a seasonal killifish (Ref. 27139).
Life cycle and mating behavior
Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
1 - 2 eggs are visible through the transparent body of the female. Viviparity is facultative, as the eggs can be laid prematurely and be attached to plants (Ref. 35237).

50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
