Dorsale zachte stralen (totaal) : 10 - 11; Anale zachte stralen: 20 - 25; Wervels: 31 - 33. Astyanax tamiahua is distinguished from other congeners in Veracruz and northern Mexico by the following characters: body deeper, mean 35.9% SL (vs. mean 33.9% SL in A. argentatus); head length, more than 26% SL (vs. 26% or less in A. acatlanensis, A. argentatus and A. rioverde); in lateral view, supraoccipital slightly concave (vs. angled in A. finitimus); infraorbital II, triangular with an angled base (vs. with a long convex base in A. argentatus and A. mexicanus); first dorsal pterygiophore, rostral edge angled (vs. curved in A. argentatus and A. mexicanus) (Ref. 118583).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01148 (0.00526 - 0.02507), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 2.9 ±0.4 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

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