Kurzbeschreibung
Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt): 0; Rückenflossenweichstrahlen (insgesamt): 12; Afterflossenstacheln 0; Afterflossenweichstrahlen: 21 - 27. Distinguished from all Astyanax congeners by the possession of a shallow body (body depth 34.9-39.4% SL); 3-4 maxillary teeth; the insertion of the fifth tooth of the inner premaxillary series posterior to main series; presence of two humeral spots, second humeral spot distinctly vertically elongated and sometimes wider than the first; the presence of 34-36 perforated scales in the lateral series, and iv-v, 20-22 anal fin rays (Ref. 46822). Olive green, iridescent gold in color; red pigmentation on last 4 or 5 procurrent rays, unbranched principal rays and on 3 branched principal rays in each caudal fin lobe, except on distal portion of those rays; yellowish area bounding this red caudal portion; adipose fin and base of anal fins yellowish (Ref. 46822).
Inhabits streams with depths ranging from less than 1 m to over 2 m (Ref. 46822).

50 = 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): 3.1 ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
