Most females spawn for the first time at 1 year, males at 2 years, in April-May, rarely until July. Adhesive eggs are deposited on stones, shells and aquatic plants and the males guard the eggs after hatching. Feeds mostly on small fish, as well as a wide variety of invertebrates (Ref.59043).

This species is different from N. kessleri in the area in having a distinctive karyotype, some osteological characters and cycloid scales on opercle and anterior part of the nape (vs. ctenoid) (Ref. 59043).
