وصف مختصر
مفاتيح التعريف | الوصف الخارجي | قياسات المظهر الخارجي
This species has the following characters: pigmented body; functional eyes; dorsal fin base 14.4-19.4% of SL; origin of adipose fin anterior to the anus; maxillary barbels extend beyond pelvic fin origin; adipose fin insertion closer to the dorsal fin than to the caudal fin; brown body with a distinct lateral longitudinal dark band (Ref. 108688).
This species occupies main channel of rivers and streams, either with turbid waters and high sediment loads or with transparent waters and few nutrients. It prefers pools and slow-flowing waters of different depths and has plant material deposits and heavy substrates such as rocks and stones which serve as shelter for this fish during the day (Ref. 108688).
