Short description Morphology | Morphometrics

Dorsal soft rays (total): 14-17; Anal soft rays: 15 - 18. This species is distinguished from its congeners in having the following characters: in males, the red caudal fin has narrow black margins at the upper and lower corners, narrow white margin to dorsal and anal fins, and silver iris; in females, flanks with irregularly dispersed black spots and on the basal half of the unpaired fins. This species differs from N. lucius in having a plain red caudal fin with narrow margin at the upper and lower corners in male (Ref. 83514).

Biology     Glossary (e.g. epibenthic)

Occurs in temporary pools in floodplains, rice fields, swamps, ditches and small streams (Ref. 3788). Found in water-filled depressions in floodplains of rivers; with vegetation often near edges, usually grasses; occasionally grasses cover the entire pool; if aquatic vegetation is present, it may comprise of Nymphea, Ottelia, Lagarosiphon, and Utricularia species; annual species; eggs deposited in substrate where they survive dry season; hatching at onset of wet season; rapid growth of fry; sexual maturity may be attained in six weeks; may be associated with other annual or non-annual fish species (Ref. 83514). Bottom spawner; 4 months incubation; difficult to maintain in aquarium (Ref. 27139).
