Ah ok. Yeah I'd check your local lakes and rivers there should be snakeheads living there. If not check the local fish markets usually they have them there as well.
The Assam region in India is where you will find a rich assortment of Snakeheads. Species such as Channa bleheri, Channa barca, Channa marulius, Channa orientalis, Channa punctata, Channa striatus and Channa stewartii.
