Краткое описание
определительные ключи | морфология | морфометрия
членистые (мягкие) лучи спинного плавника (общее число) : 11; членистые (мягкие) лучи анального плавника: 30 - 31; позвонки: 34 - 35. Diagnosed from other species of the genus Hyphessobrycon by the following characters: dorsal fin with 3 simple and 8 branched rays (vs. 2 simple and 9 branched rays, except Hyphessobrycon notidanos with iii, 8); anal fin with 4 simple and 26-27 branched rays (vs. 3 simple and 17-24 branched rays); dentary teeth 19 (vs. 6-12); scales on lateral line 35 (vs. 31-34, except for Hyphessobrycon heterorhabdus with 37); pored lateral line scales 10-11 (vs. 8-9); longitudinal scale rows from the lateral line to the dorsal fin 7 (vs. 5, except in Hyphessobrycon heterorhabdus with 7) and predorsal scales 14 (vs. 10-11). Differs from a very similar species Hyphessobrycon notidanos by the possession of the following characters: lateral line scales 35 (vs. 32-34); pored scales 12-14 (vs. 9-11);
scale rows between dorsal-fin origin and lateral line 7 (vs. 6); predorsal median scales 12-14 (vs. 9-11); teeth in the dentary 19 (vs. 7); teeth in the maxillary 5-6 (vs. 2-4); dorsal-fin rays iv, 26-27 (vs. iii, 17-20); body depth 37.84-45.59% SL (vs. 36.84-37.79% SL); and snout-anal fin distance 56.71-65.05% SL (vs. 62.52-80.39% SL) (Ref. 76880).
Occurs in clear water over substrate of sand and stone (Ref. 76880). Feeds on insects and plant matter (Ref. 76880).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00683 - 0.03057), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.6 ±0.26 se; based on food items.
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
