Malay Combtail Gourami Tank Setup
Give them at least 170 litres (45 US gallons) with gentle flow, water at 70-79°F, and a pH around 6-7.8. Gouramis breathe air at the surface, so keep it clear of thick film. They reach about 20 cm as adults, so don't be misled by the small juveniles sold in stores.
What Do Malay Combtail Gouramis Eat?
They're not fussy eaters - feed a varied diet, rotating good-quality dry, frozen, and gel foods rather than the same thing every day, and match the food size to their mouths.
Malay Combtail Gourami Tank Mates
The Malay Combtail Gourami is semi-aggressive, which is the first thing to weigh up when you choose tank mates. At around 20 cm fully grown, it needs tank mates that can hold their own against its size and appetite. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are Malay Combtail Gouramis Good for Beginners?
Doable once you test water regularly and catch problems before fish look sick. If this is your first tank, pick something more forgiving and come back later.
