Captured in creeks with rocky bottoms and in areas where the water changes level (Ref. 27188). Lies hidden under rocks and Podostemaceae. Its color pattern, like that of the other Heptapterus, provides perfect camouflage. The species which occur more frequently with it are: Imparfinis minutus, Moenkhausia oligolepis, Pyrrhulina filamentosa, Characidium fasciadorsale [= Characidium zebra] and Crenicichla albopunctata (Ref. 35381).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00851 (0.00473 - 0.01530), b=3.00 (2.85 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.6 ±0.4 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (11 of 100).
