Max length : 6.4 cm TL male/unsexed; (Ref. 5723); common length : 4.1 cm TL male/unsexed; (Ref. 12193); max. reported age: 3.00 years (Ref. 12193)

Biology     Glossary (e.g. epibenthic)

Adults occur mainly along weedy bays and backwaters, entering brackish water and to a limited extent, fresh water (Ref. 3814). Feed along the bottom, primarily on diatoms, worms and crustaceans by sucking in the prey with a pipetting action (Ref. 27549). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 4.2 - 12.7, mean 6.4 °C (based on 228 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00408 - 0.02689), b=3.07 (2.85 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.38 se; based on food items.
Generation time: 1.3 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (K=0.84; tmax=3).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (16 of 100).
Price category (Ref. 80766):   Unknown.
