Water depth is less important but should not be less than 30 cm.
Like most smaller Channa species it prefers a dimly-lit aquarium with plenty of cover in the form of live plants, driftwood branches, terracotta pipes, plant pots, etc., arranged to form a network of nooks, crannies, and shaded spots.
Surface vegetation such as Ceratopteris spp. is also appreciated and makes the fish less inclined to conceal themselves.
It’s essential to use a tightly-fitting cover since Channa spp. are notorious for their ability to escape, and a gap should be left between this and the water surface as they require access to a layer of humid air.
