I got a 12 inch florida gar from a friend who fed him tilapia, shrimp, and hikari sticks...Ive had him for about 5 days now and he still has not eaten. Ive tried earthworms, beefheart, shrimp, and massivore but he still wont eat..Ive even dropped the worm over his mouth and he does nothing...should I be worried yet or will he come around? Hes in with 2 oscars and 2 bichirs that dont bother him at all
