Toothed predator fish?

Actually you can own a Snakehead.Just not legally.Ive seen over 20 of them just this past summer in a James River estuary.Then again i killed the ones i could catch.They are killing off the habitat where i live and do nothing but eat "everything" in existance .I dont like these fish because they eat the baby game fish,that i fish for.Like b,brim,and blue catfish.
