Aquamax or Game fish chow are both good feeds. It all depends on what you are wanting to spend. I feed aquamax 500 in all my feeders and even the small 3-4" Bluegill will eat it. Have you thought about buying a feeder to make sure that they get feed a couple of times a day in the same spot. Im sure there are days when you just can't find the time to feed them or forget. This might help spur there feeding habits.
