Diagnosis: Distinguished by the following combination of characters: three prominent stripes consisting of dark spots along the sides of the abdomen, 2 postlachrymal infraorbital pores, 5 dentary pores, low dorsal fin in adult males, and presence of a caudal spot (Ref. 56722).
Occurs in association with rapids, with very fast running water; lots of aquatic plants (Podostemonaceae) which grow on the rocks. During the dry season most of the rocks are exposed, and many pools are formed where the fishes are trapped and easily collected with rotenone. Stomach analyses of five specimens (19-24 mm) from rapids showed that aquatic invertebrates were the most important food items consumed by this species; rhizopods were the dominant item, followed by sponges and cladocerans. Both males and females dissected have well developed gonads (Ref. 56722).
