Etymology: Pseudomugil: Greek, pseudes = false + Latin, mugil, -is = grey mullet (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; pelagic-neritic. Tropical; 22°C - 31°C
Western Pacific: northern Australia, near Broome and between Darwin and Wyndham, Northern Territory.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 3.5 cm TL male/unsexed; (Ref. 9786)
(total): 3 - 5;
soft rays: 9 - 13. Premaxilla wide, its ascending process short and lateral process absent. Vomer wide and slightly curved. Mesethmoid absent. Second dorsal fin with no spines and 4-7 soft rays. Pectoral fins with no spines. Midlateral scales 22-26. Elongated rays and base of second dorsal fin black.
Inhabits mangrove swamps and highly saline creeks flowing into estuaries, usually swimming over muddy bottom. Often congregate in large numbers. May be found in hypersaline waters (28-40 ppt) and in relatively high temperatures (22-31°C). Breeding has been achieved in aquaria; the eggs take about two weeks to hatch and young fish reach adulthood in only three months (Ref. 44894). A small but attractive species.
