that's not true.
many of us here do not feed them feeders (lfs do because that's easier for them). I feed all mine smelts, fish fillet, shrimp, squid, etc none of them had problem eating those food.
piranhas feed off the wounded, sick or dead in the wild so there's no reason they won't eat a piece of fillet or smelt. some might be a bit hard to go from hunting moving prey to a dead meat but they won't starve themselves and all will eventually eat what you give them.
