will beat me to the punch! lol i have known people to feed feeder fish to various drymarchon, water snakes, and garter snakes in order to get picky hatchlings to start feeding. personally, i would not like to clean cages behind a room full of hogs that have been fed fish :-p would probably still be better than drymarchon poo though. lol

about the parasites, i'm not sure there. i read a care sheet article by a garter snake breeder that recommended against feeder fish just because of that reason. you might poke around on those forums. bet they would have some good info to share
