If you don't have any forceps or long plastic tweezers one thing you can try is getting some wooden skewers and reptomin.

If you wet the reptomin a little it will stick to the flat end of the skewer (dont use the pointy side) and then you can just put the food right in front of your frogs mouth. I feed my ACF like this since some of my frogs are more skilled at finding food than others and wind up hogging it.
