This snakehead, often traded under the name Channa cf. barca, originates from the northern Indian province of Assam. C. stewartii can reach a length of up to 30 cm (usually around 20 cm) and as a predatory fish should only be kept along with fish that are at least 2/3 of its body length. Besides living and dead fish they accept as food insects, worms, coarse frozen food and after habituation also food sticks.
Since their area of occurrence is not in the tropical area, they can be kept well in the unheated aquarium. They tolerate temperatures between 15 – 30°C, also to the water parameters only small requirements are made. Since they can breathe atmospheric air in addition to gill breathing, the oxygen content of the water is of secondary importance.
