Longest mine went was about 4 or 5 days, and that was a good long while back. Just today during feeding my armatus picked up a large piece off the tile, he'll do it from time to time - not a daily thing. Just keep trying, not many animals will willingly starve themselves to death unless there is some underlying problem.
You could try re-arranging the tank decor, break up each fishes territory and let them readjust on their own. Give them a day or two then try feeding again.
Hope everything works out for you man. I know these fish can be a pita sometimes.
