Banded Gourami

The banded gourami is a small, colorful labyrinth fish native to slow-moving freshwater habitats across the Indian subcontinent, from the Indus basin east through Bangladesh and Myanmar. Like other anabantoids, it possesses a specialized labyrinth organ that lets it breathe atmospheric air, allowing it to survive in stagnant, oxygen-depleted ponds, ditches, and flooded rice paddies where many other fish cannot. Adults display an attractive pattern of diagonal orange-red bands over a blue-green body, with males coloring up more intensely during the breeding season. It is a popular aquarium species valued for its hardiness, moderate size, and relatively peaceful temperament compared to some other gourami relatives. Wild populations remain widespread and are not considered threatened.

• Laterally compressed, elongated body typical of gouramis
• Base color blue-green to olive, overlaid with 6-8 diagonal orange-red stripes
• Long, thin, thread-like pelvic fins used as tactile feelers
• Pointed, slightly extended snout and upturned mouth
• Males show brighter colors and longer dorsal/anal fin points than females
• Distinguished from the similar dwarf gourami by larger size and coarser, less iridescent striping
• Rounded caudal fin, unlike the forked tails of many open-water fish

Banded gouramis inhabit slow or still freshwater across South Asia, including India, Bangladesh, Nepal, and parts of Myanmar. They favor densely vegetated ponds, ditches, swamps, oxbow lakes, and flooded agricultural fields such as rice paddies, where water is warm, shallow, and often low in dissolved oxygen. Their labyrinth organ, an accessory breathing structure above the gills, lets them gulp air at the surface, so they thrive in stagnant or seasonally drying habitats unsuitable for most fish. During monsoon flooding they disperse into newly inundated fields and ditches, retreating to permanent water bodies as the dry season progresses. They tolerate a wide temperature range and murky, tannin-stained water typical of the region's lowland wetlands.

Banded gouramis are omnivorous, picking at small invertebrates, insect larvae, zooplankton, and algae from vegetation and the water's surface. They are generally peaceful but males become territorial when breeding, building floating bubble nests among plants or debris at the surface. After a courtship display, the male wraps around the female to induce spawning, then gathers the eggs into the nest and guards them fiercely, fanning water to keep them oxygenated until they hatch. Outside the breeding season they are loosely social, often sheltering among plant stems in small, non-aggressive groups. Their labyrinth organ requires regular access to the surface, so individuals make frequent trips to gulp air even in well-oxygenated water.
