Etymology: Rasbora: Rasbora, an Indian word for a fish, also used in Malay peninsula.
Environment: milieu / climate zone / depth range / distribution range
पारिस्थितिकी
; स्वच्छ जल, अलवण जल बेनथोपिलाजिक. Tropical

पृष्ठीय सौफट रेज़ (सम्पूर्ण): 9; ऐनल सौफट रेज़: 7; जानवरों की रीड़ का जोड़: 31 - 32. Distinguished from all members Rasbora trifasciata-group by having male cephalic tubercles conical, distinctly pointed, with shallow, wide depression basally, and an axial streak
bordering the dorsal margin of the black midlateral stripe along its posterior portion, barely traversing the stripe (vs. traversing the medioposterior portion of the black midlateral stripe). Can be further diagnosed from other members in northwestern Sumatra by the following combination of characters: presence of cranial superficial neuromasts (each basal plate of the neuromast is confluent with the skin surface and surrounded by a peripheral groove); first infraorbital (lachrymal) with a posterodorsal process and a concave dorsal margin; the uniformly pigmented lachrymal region; a dorsomedial branch of the supraorbital canal extending toward the posterior margin of the frontal; the cephalic tubercles, which are present only in males; a pigmented opercular flap; a transverse scale count anterior to the dorsal-fin origin and pelvic-fin insertion of K4/1/2K; 12 scales around caudal peduncle; a basal reticulation pattern consisting of a network of well-developed parenthesis-shaped bars on the midlateral surface of the body; the maximum vertical coverage of the basal reticulation by four and a half longitudinal scale rows; all scales of the lateral line series that are pigmented as a continuation of the basal reticulation; and pelvic-fin rays i,7 (Ref. 85846).
