Origin and habitat

Native to the Mekong and Chao Phraya basins of mainland Southeast Asia, across Laos, Thailand, Cambodia and Vietnam, in marshes, swamps, floodplains and slow rivers. A labyrinth fish of the family Osphronemidae, formerly placed in Trichogaster, it breathes air through a labyrinth organ and so endures water with very little oxygen. The common name comes from the snake-like banding on its flanks. It is the largest of the Trichopodus gouramis, reaching about 25 cm, with most fish around 15 cm, and it carries a high meat yield for its size, with firm, mild, relatively boneless flesh. Snakeskin gourami ranks among Thailand's top five farmed freshwater fishes and is a rural protein staple in Cambodia, often sold dried. It has been moved into aquaculture beyond its native range, including tropical Africa, South Asia and Indonesia.

Care notes

A warm-water food fish for tropical aquaponics where it is established and valued. It grows best in the high 20s Celsius within a band of about 2232°C, reaching roughly 200400 g in 8 to 12 months on pellet of 25 to 32 percent protein, or more cheaply in fertilised ponds where it grazes algae, plants, zooplankton and detritus. Feed conversion on pellet runs about 1.5 to 2.5, and the broad, mostly herbivorous diet keeps feed costs down in integrated systems. The labyrinth organ lets it tolerate dissolved oxygen down around 1 mg/L, a useful buffer against pump or power failure, so it can be stocked fairly densely, near {density:15}-{density:25}. Water-quality tolerance is wide across pH, temperature and hardness. Breeding is easy: the male builds a surface bubble nest, gathers the fertilised eggs into it and guards them, with both parents tending the fry, so hatcheries across Thailand, Cambodia and Vietnam supply cheap fingerlings. It is rarely farmed outside tropical Asia. For Southeast Asian growers it is a practical, affordable and culturally fitting choice.
