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