Prefers a dimly-lit aquarium with a layer of surface vegetation such as Ceratopteris spp. plus some submerged cover.
It is essential to use a tightly-fitting hood 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.
More importantly still C. bleheri must not be maintained at a constant temperature but provided with natural seasonal variation in the form of defined winter and summer periods. During the colder period the fish do not require much food and the water level can be allowed to fall without additional top-ups.
Young fish can be offered chironomid larvae (bloodworm), small earthworms, chopped prawn and suchlike, while adults will accept strips of fish flesh, whole prawns, mussels, live river shrimp, larger earthworms, etc.
