Comments: Usually found in floating meadow habitats, composed mostly of the grass <i>Paspalum repens</i>, Poaceae.  Occurs mainly in white water, but also in areas near the confluence of black water rivers with the Amazonas/Solimões ranging from low to medium conductivity.  Syntopic with the species of <i>Eigenmannia</i>, <i>Gymnotus</i>, the apteronotid <i>Parapteronotus hasemani</i> and the electric eel <i>Electrophorus electricus</i> in the floating meadow habitats (Ref. 94132).
