A stenotypic inhabitant of peat swamp forests and associated blackwater streams, in some of which it occurs sympatrically with the congener P. opalios.
In unaltered habitats the dense canopy of branches above means very little light penetrates the surface of such environments, and riparian vegetation also tends to grow thickly.
The water is typically stained darkly with humic acids and other chemicals released by decaying organic materials, the dissolved mineral content generally negligible and pH as low as 3.0 or 4.0.
Unfortunately in many cases it now survives only in remnants of heavily-modified peat swamps such as irrigation ditches and roadside canals and appears in danger of extinction.
Can be maintained in a fully-decorated aquarium although many breeders prefer not to use a substrate for ease of maintenance.
Driftwood roots and branches can be used and placed such a way that a few shady spots are formed, and clay plant pots, lengths of piping or even plastic camera-film containers can be included to provide further shelter and potential spawning sites.
