Adults inhabit salt and brackish waters of bays and estuaries, penetrating into fresh water (Ref. 1601). Juveniles are sometimes found in streams within 5-10 km of the sea (Ref. 2847). Eggs are guarded and fanned by the male parent (Ref. 205).

Bayesian length-weight: a=0.01288 (0.00598 - 0.02775), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.37 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (18 of 100).
