Just about anything they want! There were baitfish and reef fish of different species in them Jay. Those we caught last week had mostly squid in them. Red snapper are amazingly fast for short spurts and very aggressive. We did lose a few to jewfish and sharks. A jewfish (goliath grouper) ate probably my biggest fish of the day. I've come to really dislike them. They eat 20 pound snapper and grouper like an hors d’oeuvres.Ray, what are those snappers feeding on with those fat bellies?
