Actually....there are states in which it is legal to keep snakeheads. The Federal government banned the importation of live snakeheads and their eggs across state lines or into the United States. In states where they are still legal you can have as many snakeheads as you want but you can't transport them out of the state. New York is one of the states where ALL species of the snakeheads (Channidae) are illegal. Here is the list of restricted/prohibited fish for New York:
