Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt) : 11; Mjukstrålar i analfenan: 24 - 28; Ryggkotor: 35. Distinguished from its congeners by the presence of an unpigmented, horizontally-oriented, roughly oval area on the proximal portion of the caudal-fin lobes, bordered posteriorly by dark pigmentation (Ref. 54762).
Body shape (shape guide): short and / or deep.
Collected exclusively by seining beaches in pools immediately downstream of waterfalls or rapids, but not in the rapids themselves (Ref. 54762). Apparently avoids small forest streams (Ref. 54762). Feeds on filamentous algae, fragments of Podostemaceae, terrestrial and aquatic Hemipterans, adults and larvae of Trichopterans and odonate nymphs (Ref. 54762).
