Stenogobius fehlmanni Watson 1991

Spines of 1st dorsal fins in males usually filamentous, may reach seventh or eight ray of 2nd dorsal fin; scale count in lateral series 46-51, usually 48-50; scales in predorsal midline almost always naked; opercle may or may not be scaled; cheek almost always naked; breast always scales.

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): 7; Dorsal soft rays (total): 11; Analspines: 1; Analsoft rays: 11 - 12

Reported from fresh and brackish water streams over sand and mud (Ref. 34009).
