Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 21.0 cm TL male/unsexed; (Ref. 2850); common length : 13.0 cm TL male/unsexed; (Ref. 12193); max. reported age: 2.00 years (Ref. 56049)

Facultative air-breathing (Ref. 126274); Inhabits tidal flats, bays and coastal sloughs. Prefers mud bottom in shallow water. Non-emerging air-breather (Ref. 31184). Oviparous (Ref. 56079). Males guard the eggs which are found attached to the walls of brood chamber (Ref. 56079).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Female lays several thousand club-shaped eggs in nest built by male. Male guards eggs during 10-12 day incubation.

Estimates based on models

Preferred temperature (Ref. 123201): 14.5 - 25.9, mean 22.3 °C (based on 138 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00506 - 0.01977), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.35 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (tmax=2;).

Fishing Vulnerability (Ref. 59153): Low vulnerability (11 of 100).
