Short description Identification keys | Morphology | Morphometrics

This species is distinguished by the following characters in males: anal and caudal fins light blue with a proximal brown spots, with brown median band, followed by a light blue subdistal and black distal bands; dorsal fin golden with brown spots and brown irregular stripes, with narrow black distal band. Colouration: body coloration light blue with seven to ten red-brown irregular vertical stripes. Differs from N. taeniopygus by having a greater head length of 35.0-38.6% SL (vs. 30.2-34.6); smaller head width of 50-57% HL (vs. 59-63); smaller head depth of 71-80% HL (vs. 89-98); smaller interorbital width of 31-40% HL (vs. 45-47); and smaller postorbital length of 44-51 % HL (vs. 55-63) (Ref. 128031).

Inhabits ephemeral pool and swamps of Apapi River system. This species is a micropredator, feeding on small aquatic crustaceans, worms, insect larvae and other zooplankton (Ref. 128031).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00472 - 0.02669), b=2.94 (2.74 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
