📖 Overview

A short-lived species reported to live in fast-flowing rivers with a gravel substrate . Occurs in main course of rivers and large streams and in riffles. Found on stone bottom . Lurks on the bottom during the day and comes out for crepuscular feeding . Feeds on aquatic invertebrates. Larvae feed on plankton under surface, then at about 2.5 cm SL, they move to benthic habitats. Attains first sexual maturity at 2-4 years of age. Spawns in deeper parts of riffles. Deposits on gravel strongly adhesive eggs, 2.2 mm in diameter, which hatch in about 14 days at 13° C . Threatened due to habitat destruction and pollution .

🐟 Physical Description

Dorsal spines (total): 8 - 13; Dorsal soft rays (total): 10 - 14; Anal spines: 1 - 3; Anal soft rays: 8 - 12; Vertebrae: 43 - 45. The presence of 57-65 + 3-6 scales along lateral line distinguishes uniquely this species from its congeners. Can be further separated from other species by the combination of the following characters: first dorsal fin with 8-9 spines; second dorsal fin with 1-2 simple and 9-12½ branched rays; scaleless cheeks . Caudal fin with 17 soft rays .: elongated.
