Wolves are really very easy to get onto dead foods, the problems is that your wolf has been eating live foods for a while so he needs to recognize prepared foods as food. Just simply stop feeding him feeders and start feeding him night crawlers. It is still alive so it squirming around will attract his attention but he will get used to things not looking like fish being food.
After he starts sucking those down readily, don't feed for 3 days and try a thawed shrimp or silverside. If he accepts it great; if not, skip a day and try again. It shouldn't take long.
edit: good luck
