duri punggung lunak (Keseluruhan (total)) : 11 - 12; vertebrata, bertulang belakang: 33 - 34. The unique color pattern of the body consisting of a black midlateral stripe which extends from the posterior margin of the eye to the median caudal-fin rays distinguishes Hemigrammus ataktos from all congeners which possess dark stripe or thin line extending approximately from the humeral blotch or from the vertical through dorsal-fin origin to the caudal fin. It differs also from all congeners, except H. filamentosus Zarske, by having elongated anteriormost portions of the dorsal, pelvic, and anal fins in mature males (Ref. 96858).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.4 se; based on size and trophs of closest relatives

Daya lenting (Ref. 120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).

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