I guess like people, snakes each have their preference. Mine have all seemed to take the fish, pinky, worm, etc thing pretty much without incident. They will, however, at times stick up their little snakey noses at the offered dinner of the day. At that point, it's wait a few days and try again or try something else. I know they like & eat it, so the question is not "if" but "when" and then "what". To each his own...
