Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 3; Dorsal soft rays (total): 7 - 8; Anal spines: 3; Anal soft rays: 9 - 10; Vertebrae: 30. Can be diagnosed from all its congeners by the following characters: pre-dorsal scales 15-16; predorsal length 60.68% of SL; preanal length 65-71% of SL; eye diameter 27-38% of HL and 70-93% of inter-orbital width; and dorsal fin origin posterior to pelvic fin insertion (Ref. 75599).
Body shape (shape guide): elongated; Cross section: compressed.
Occurs in small hill stream with sandy bottom and numerous cobblestones. Food items found in the intestines include zooplankton and phytoplankton (Ref. 75599).
