I think this happens to everyone. A trick I had learned, depending on how big your duncan is or piece your trying to feed...
Take a water bottle or gatorade and cut the bottom off. Put it over the coral and feed it from the hole on the top. Fish won't be able to get in through the hole on the top and you won't even need to worry about current etc. etc.
