Occurs in swamps, heavily vegetated sloughs and small sluggish streams, usually over mud. Feeds on worms and crustaceans (Ref. 7020). Oviparous, eggs are deposited in aquatic vegetation, preferably on strands of Ceratophyllum sp. when available (Ref. 58020).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00205 - 0.01470), b=3.14 (2.90 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.40 se; based on food items.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Fec=25).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
