Snakeskin Gourami

The Snakeskin Gourami is native to the lowland floodplains, canals, and rice-growing wetlands of Thailand, Cambodia, Vietnam, and Laos, and has been introduced to other parts of Southeast Asia. It is named for the pattern of diagonal dark striping across its olive-brown to greenish-grey flanks, which resembles the scale pattern of a snake. Larger and more elongated than most ornamental gouramis, it can reach lengths of around 25 cm, making it one of the bigger species in the family aside from the Giant Gourami. Like its relatives, it possesses a labyrinth organ that allows it to breathe atmospheric air, an important adaptation to the seasonally oxygen-poor floodplain and paddy habitats it occupies throughout much of its range.

• Elongated, moderately deep body, olive-brown to greenish-grey overall
• Prominent diagonal dark stripe running from the eye back toward the tail, with additional fainter diagonal lines creating a snakeskin-like texture
• Long, thin, thread-like pelvic fins typical of gouramis
• Pointed dorsal and anal fins, more elongated in males
• Larger overall size than most other Trichopodus species, second only to the Giant Gourami among common gouramis
• Distinguished from the Three Spot Gourami by its diagonal striped pattern rather than discrete round spots

Snakeskin Gouramis are native to the floodplains, canals, ditches, and rice paddies of Thailand, Cambodia, Vietnam, and Laos, thriving in the seasonally flooded wetlands typical of the lower Mekong and Chao Phraya basins. They favor warm, still to slow-moving freshwater with abundant vegetation and tolerate low-oxygen conditions well, using a labyrinth organ to breathe air at the surface. The species is closely associated with agricultural wetlands, expanding into flooded rice fields during the monsoon season and retreating to permanent canals, ponds, and river channels during the dry season, a seasonal habitat shift shared with several other Southeast Asian floodplain fish.

Snakeskin Gouramis are active, hardy fish that forage widely through the water column for insects, crustaceans, worms, algae, and plant material, reflecting a broadly omnivorous diet. As labyrinth breathers, they regularly surface to gulp air, an adaptation that helps them survive in the low-oxygen, seasonally flooded wetlands of their native range. During the breeding season, males build bubble nests among floating vegetation and defend a territory, performing courtship displays to attract females. After an embrace-style spawning, the male gathers the floating eggs into the nest and guards both eggs and fry, chasing off intruders until the fry disperse and become independent swimmers.
