Etymology: schwanefeldii: Named for military surgeon H. W. Schwanefeld, who collected the type series.
Eponymy: Lieutenant Colonel H W Schwanefeld was a Dutch military surgeon. He collected both of the types in West Sumatra. Bleeker misspelled his name in the binomials; a mistake he subsequently corrected but the original spelling must, by convention, be retained. (Ref. 128868), visit book page.

पृष्ठीय रीढ़ (सम्पूर्ण) : 3; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 8; गुदा कांटा: 3; ऐनल सौफट रेज़: 5. Distinguished from other species of the genus in having a red dorsal fin with a black blotch at the tip, red pectoral, pelvic and anal fins, red caudal fin with white margin and a black submarginal stripe along each lobe, and 8 scale rows between dorsal-fin origin and lateral line (Ref. 27732). Large individuals silvery or golden yellow in life with its dorsal fin red and caudal fin orange or blood-red (Ref. 2091).
Found in rivers, streams, canals and ditches (Ref. 12693). Occurs in medium to large-sized rivers and enters flooded fields (Ref. 12975). In east Kalimantan, Indonesia a temperature range of 20.4-33.7°C was recorded for this species (Ref. 6129). Largely herbivorous, consuming aquatic macrophytes and submerged land plants, as well as filamentous algae and occasionally insects (Ref. 12693). Also feeds on small fishes (Ref. 12693), worms and crustaceans (Ref. 7020). Usually marketed fresh (Ref. 12693).
