Collected from a small creek, quite sunny, with amber-colored water, slow current, muddy substrate and approximately 1 m in depth. Solitary. Feeds on shrimps, insect larvae of Odonata, Coleoptera and Hemiptera, as well as on fishes like cyprinodonts, characids. Males are bigger than females. Reproduction occurs during the rainy season. Found together with Pterophyllum scalare, Heros efasciatus, Hypselecara temporalis, and Mesonauta guyanae (Ref. 35237). Maximum length 25 cm TL (Ref. 2060).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02042 (0.00927 - 0.04498), b=3.11 (2.92 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.7 ±0.57 se; based on food items.

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

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

Price category (Ref. 80766): Unknown.
