Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 34.0 cm SL male/unsexed; (Ref. 44894); common length : 15.0 cm SL male/unsexed; (Ref. 44894)
Found in freshwater, estuaries, inshore and mangrove (Ref. 86252). Adults occur on soft mud bottoms of rainforest creeks to elevations of at least 150 m. (Ref. 2847, 44894). They favor undercut banks for retreat. Probably has a pelagic marine larval stage (Ref. 44894).

Estimates based on models
Preferred temperature (Ref.
123201): 27.4 - 29.4, mean 28.8 °C (based on 981 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00420 - 0.02379), b=3.08 (2.88 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (31 of 100).
