Ok so ive had my florida gar for about a month now and in that whole time ive only seen him eat ONE small piece of shrimp...the guy I got him from said he fed him tilapia and market shrimp...every day i put one or the other in the tank for him and he always seems interested but never eats...Unless hes eating the leftovers when I turn the lights out?? Would he have lasted this long without eating and are there any other methods I can try to get him to eat?
