Etymology: Rasbora: Rasbora, an Indian word for a fish, also used in Malay peninsula; api: Name refers to fire in Bahasa Indonesia, in reference to the vermilion coloration of the dorsal and caudal fins and the orange-yellowish parts of the species in life, a pigmentation pattern appearing like fire.

Short description
ຕົວທີ່ໃຊ້ໃນການຈຳແນກຊະນິດ | ສະລີລະວິທະຍາ | ການວັດແທກຮູບຮ່າງລັກສະນະພາຍນອກຂອງດິນ,ສັດ,ປາ…
ຄີຫຼັງຂອງປາ (ຄີອ່ອນ) (ທັງໝົດ) : 9; ຄີກົ້ນຂອງປາ: 7; ສັດທີ່ມີກະດູກສັນຫຼັງ: 31 - 32. Can be distinguished from all members of the Rasbora trifasciata-group by the following characters: anteriorly tapering black midlateral stripe extending along the flank from the post-opercular region to the base of the caudal fin and terminating posteriorly at the black basicaudal spot on the base of the caudal fin; cephalic tubercles of males are relatively stout and tall, with the base of the tubercle at the skin surface, and with epithelial cells on the basal surface bearing microgranules.; and a vermilion coloration on the dorsal and caudal fins in life. Differs further from other members in northwestern Sumatra by the following combination of characters: Type I cranial superficial neuromasts (basal plate confluent with the skin surface with no peripheral structure surrounding it); the symphyseal knob of the dentary strongly developed; the conspicuous depression on the lateroventral margin of the upper jaw which is notched by a deep lachrymal groove; the first infraorbital (lachrymal) with a posterodorsal process and a concave dorsal margin; the lachrymal region that is peripherally pigmented with an unpigmented central area; the dorsomedial branch of the supraorbital canal toward the posterior margin of frontal; the sphenotic that is exposed dorsal to the supraorbital canal; ten gill rakers on first arch; an axial streak reaching anteriorly to the pectoral girdle; the presence of cephalic tubercles on the ventral surface of lower jaw of both sexes; a transverse scale count anterior to the dorsal-fin origin and pelvic-fin insertion of K4/1/3K; 10 scales around caudal peduncle; a basal reticulation pattern comprised of networks of well-developed chevron-shaped bars on the midlateral surface of the body; the maximum vertical coverage of the basal reticulation of four longitudinal scale rows; and pelvic-fin rays i,7-8 (Ref. 85846).
Inhabits gravel-bottomed mountain streams, moderate flowing turbid rivers, and acidic blackwater peatswamps. Occurs sympatrically with Rasbora jacobsoni, R. truncata, and R. cf. sumatrana in the Kluet and Alas river basins (Ref. 85846).
