Do I have to feed it live food. ? What else can I feed it beside live food ? Thanks
What species are you going for?
As different species will definitely have different requirements and needs.
Some snakeheads are from riverine habitats, some are from hill streams, some from swamps.
Similarly some are predominantly piscivore, some are predominantly insectivore, some are topwater hunters, that means anything and everything is good.
So unless we know what species it's gonna be difficult to ascertain what all is a good choice of food.
