Vertebrae: 26. This relatively elongated species which reaches more than 12 cm TL, is distinguished from all species except A. kaaygua in having a modal count of 12 pectoral fin rays; differs from A. facetus, cf. facetus, and guarani, by having modally 6 C1 gill rakers; differs facetus in not having an upwards directed mouth and a longer dorsal fin scale cover, covering bases of 7-8 last spines (vs. only 2-3). The same as A. kaaygua, it has yellowish ground color, but without the red corners of caudal fin (present in kaaygua, and also differs by being much less deep-bodied. Distinguished from all its congeners by pink to red dominant males (Ref. 74689).

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=0.01000 (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
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec<1000).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
