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).
Occurs in small hill stream with sandy bottom and numerous cobblestones. Food items found in the intestines include zooplankton and phytoplankton (Ref. 75599).
