Maturity: Lm ?  range ? - ? cm
Max length : 4.5 cm SL male/unsexed; (Ref. 26041)
Facultative air-breathing (Ref. 126274); So far, only about ten specimens have been collected of this rare species. Two were from a creek with moderate current, 0.5 to 3 m wide, shallow (20-50 cm depth) with sandy to sandy-muddy bottom and not so brightly illuminated (Ref. 35381).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00286 - 0.01921), b=3.14 (2.92 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (10 of 100).
