Stiphodon pulchellus (Herre 1927)

Distinguished by the having the following characters: usually VI-I, 9 dorsal fins, larger male with pointed first dorsal fin with elongate spines 4 and 5, posterior tip of the fin usually extending to base of soft-rays 2-5 of second dorsal fin; 14-16 (mode 15) pectoral-fin rays; 32-56 premaxillary teeth, 29-61 horizontal dentary teeth; males with nine blackish obscure transverse bars laterally on tail and clear black spots distributed over almost entire rays of pectoral fin, number of spots on the longest ray 5-10; females with two black, straight and simple longitudinal bands laterally on body, often with 1-4 black spots on second dorsal-fin rays, 2-5 black transverse bars on central part of caudal fin, and 1-7 black spots on pectoral-fin rays (Ref. 90214).

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): 8 - 10; Analspines: 1; Analsoft rays: 9 - 10; Vertebrae: 18

Inhabits relatively swift streams over boulder and gravel bottoms (Ref. 26366).
