Moonlight Gourami
Trichopodus microlepis · also called moonlight gouramis
A pale, silvery-green body catches the light with a subtle glow as a moonlight gourami drifts calmly through still water, one of the more peaceful and understated members of the gourami family kept in home aquariums.
Overview
The moonlight gourami, Trichopodus microlepis, is native to still and slow-moving fresh water across Southeast Asia. Its gently glowing pale colouring, calm temperament, and air-breathing labyrinth organ make it one of the more subtly elegant and community-friendly gouramis available to aquarium keepers.
Elegance in understatement
Rather than relying on bold colour or pattern, the moonlight gourami’s appeal comes from a quiet, pale glow across its body, a subtler kind of beauty that has made it a favourite among keepers who prefer a calmer aesthetic in a community tank.
Status
Not Evaluated for conservation status, widespread across suitable freshwater habitat throughout Southeast Asia.
