Because Thailand is one of the locations, in the world where you will have the opportunity to catch, a variety of different Snakehead fish species. The most often caught Snakehead in Thailand are the Striped Snakehead, Great Snakehead and the Giant Snakehead. It likes to stay behind snags from where it can ambush its prey.

When it’s one year old and spawns in a nest a little offshore. It is a surprisingly good parent and the male as well as the female protects the nest and eggs. The Giant Snakehead is considered gregarious; they will follow their young closely. Parents will attack everything disturbing the snakehead’s school of juveniles. This behavior wears off as the fry grow. The young are red in color, with orange and black lateral stripes appearing after about two months. As it matures, they lose their stripes and instead develop a bluish black and white pattern on their upper body. It generally feeds on other fish, frogs and birds.

They take surface lures, diving lures, popper flies and large streamers. Giant Snakehead take the lure hard and will dive to the nearest snag or cover with constant head shaking. Snakehead fishing in water with weedy and growing vegetation, with top water lures; can produce some spectacular visual surface strikes and is adrenaline fishing at its best! When fishing in deeper water with diving lures, you spot the Snakehead as it is coming up to the surface to breathe and then slowly dive down cast; as soon as possible the lure to the fish.
They are very territorial and when Giant Snakehead are taking care of their fry the first months they will attack everything that comes to close. If you spot a school of small fry coming to the surface for air, casting the lure close to the school of the fry is a good fishing technique that can be very productive, and give some of the biggest Snakehead.
Sexing: There are no apparent sexual differences, when they are sexually mature and pair up the female is the largest.
