well i have been keeping gar, large mouth bass, northern pike, walleye, and gamefish like that for a while now and have only encountered parasites due to feeding them live fish (goldfish,fatheads,etc.) only maybe 3 times. so anyway one of my spotted gar who is now about 12 inches long has a parasite due to some fatheads i fed him about a week or so ago. so I am now trying to feed him other things that aren't live fish because i want to rid him of his parasite. I have tried worms, blood worm cubes, krill, and fillets of perch he doesn't except none of them. what else should i try crickets? silversides?
