Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
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).
Body shape (shape guide): elongated; Cross section: oval.
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).
