I remember in one of viperkeeper videos (he is a hot keeper whose been breeding, selling and caring for numerous different venomous and dangerous species of snakes, including vipers), he stated that he would never sell his stock to anyone who he doesn't know, and if you have to ask how to care for a venomous snake, you shouldn't be keeping one. Hence, maybe there is a good reason you can't find care information online like you would for a corn snake.
