Feeds on plankton, including unicellular algae, diatoms and especially copepods, but also hydracarians and aquatic insects (Ref. 188, 41580). It breeds in Lake Tumba, ripe fishes being caught in late August and ripe and some spent fishes occurring in about mid-September (Ref. 188, 41580). Whitehead, P.J.P. 1985 FAO Species Catalogue.

It differs from Nannothrissa stewarti in having more gillrakers, 24-31 vs. 20-23, more anal fin rays, 20-23 vs. 17-19, and more scales in lateral series, 35-40 vs. 34-35 (Ref. 188, 2263, 94752).Description: Depth of body 4 to 5 times in its length; caudal peduncle longer than deep (Ref. 2263). Snout a little shorter than diameter of eye, which is rather more than 1/3 the length of head; lower jaw a little projecting, toothless; no teeth on pre-maxillary and maxillary; maxillary extending to vertical from anterior edge of eye; posterior supra-maxilla half as long as maxilla (Ref. 188, 2263, 93833). Lower gillrakers 24-31 (Ref. 188, 93833). Dorsal fin with 12-15 rays; anal fin with 20-23 rays; pectoral fin with 11-12 rays; pelvic fin with 1 unbranched and 6-7 branched rays, its insertion about half eye diameter before dorsal fin origin; caudal fin with 18-19 rays (Ref. 188, 2263, 93833, 94751). Scales: 35-42 in a longitudinal series (Ref. 188, 2263, 93833, 94751). Scutes very strongly keeled, beginning at isthmus or just behind; 12-15 pre-pelvic and 6-8 post-pelvic scutes (Ref. 188, 2263). Number of vertebrae 39-40 (Ref. 94751).Colouration: More or less transparent, entirely silvery with pearly blue-green and pink reflections; dorsal region slightly darker; top of head, tip of snout and chin black; eye black; ventral scutes and base of impaired fins blackish; ventral and anal fins transparent, pectoral and dorsal fins slightly darkened, lobes of caudal fin blackish; a weak black band on the caudal peduncle, widening towards the base of the latter, and clearly visible in preserved specimens (Ref. 41580).
