Snakeskin Gourami Care
Trichopodus pectoralis
The Snakeskin Gourami is a peaceful but large labyrinth fish from Southeast Asia. It needs a long aquarium with swimming space, planted shelter and unobstructed access to the surface. This guide covers care, water, feeding, tankmates and breeding. Published ranges sometimes differ, so uncertainties and measurement differences are identified rather than hidden. The species grows larger than many common community fish and may eat smaller fish. Consider the final aquarium footprint and tankmate choices before buying one. The guidance below is drawn from specialist aquarium and biological references, but it does not replace stable water quality or gradual acclimation.

About this species
Trichopodus pectoralis is a large member of the gourami family Osphronemidae. The older combination Trichogaster pectoralis is still common in aquarium references and trade. Its elongated body has dark oblique markings. FishBase gives 25 cm total length as a published maximum and 15 cm as a common length; an aquarium profile also reports 30 cm standard length. These are different measurements and cannot be directly compared. Plan for a large fish that does not belong in a small community aquarium.
Natural habitat
The species is native to drainages including the Mekong and Chao Phraya. It is reported from shallow, still or slow-moving waters with abundant aquatic vegetation, including seasonally flooded habitats. As a labyrinth fish it can breathe atmospheric air. This does not remove the need for clean water, filtration and routine maintenance.
Aquarium and layout
Seriously Fish lists a 120 × 30 cm base and calculates about 108 litres at a 30 cm water depth. The my-fish care profile recommends at least 240 litres and prefers a 150 cm long aquarium for long-term housing. This guide uses 240 litres as the more cautious starting point, not a guarantee that every aquarium of that volume is suitable. A long footprint offers more usable swimming room than a tall, narrow tank. Plant the margins densely and add floating cover, while keeping open swimming space and a clear route to the surface. Consider adult size and tankmates before choosing a setup.
Water conditions
Sources differ in their temperature and pH ranges. Seriously Fish lists 22–30 °C and pH 5.8–8.5; FishBase gives 23–28 °C and pH 6.0–8.3 as environmental data. This guide uses the narrower 23–28 °C and pH 6.0–8.3 as cautious guidance, not hard survival limits. Seriously Fish and my-fish give 2–30 °dGH for aquarium care, while FishBase separately reports 2–3 dH as environmental data. The aquarium recommendation is retained and the distinction is made clear. Acclimate gradually and keep water stable.
Behaviour and group size
The aquarium profile describes this species as very peaceful with calm tankmates that will not be intimidated by its eventual size. It may eat smaller fish. Compatibility therefore depends on adult size, swimming behaviour, feeding competition and available space, not just overlapping water values. The my-fish profile describes keeping it alone, as a pair or in a group; group size depends on aquarium space and territorial behaviour during breeding. There is no universal number for every setup. Keep the surface accessible for air breathing.
Feeding
The Snakeskin Gourami is omnivorous. Its natural diet includes plant matter and small invertebrates. Offer varied complete food, with suitable plant/algae-based foods and small animal foods as additions. Match particle size to the individual and remove leftovers. A fixed daily ration is not supported and will depend on size, temperature and feeding response.
Breeding
The male builds a surface bubble nest and guards the eggs. Breeding requires a quiet, prepared aquarium with floating cover. Seriously Fish warns that the female may be injured after spawning if she cannot leave, so plan how to separate her safely. Spawning and development vary and are not presented here as fixed promises.
