The Powder Blue Dwarf Gourami originates from a species naturally found in slow-moving rivers, ponds, and wetlands across South Asia. These habitats are typically densely vegetated and often contain lower oxygen levels than fast-flowing waterways.

Like all gouramis, this species possesses a labyrinth organ, allowing it to breathe atmospheric air. It is common to observe Powder Blue Dwarf Gouramis occasionally swimming to the surface to take a gulp of air. Their calm nature makes them excellent additions to peaceful community aquariums.
