Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Dorsal spines (total): 6 - 7; Dorsal soft rays (total): 10; Analspines: 1; Analsoft rays: 8 - 9

Inhabits mud and rock bottoms near shore in 0-4 m (Ref. 90102). Found in coastal waters, estuaries (Ref. 4833), tidal rivers, canals and creeks (Ref. 12693). Feeds on small fishes, crustaceans and insects. Not seen in markets (Ref. 12693).
